1 9-36; Rev ; 9/ SC7/SOT3-8, 5mA I, Rail-to-Rail I/O General Description The op amps deliver 4mW per channel into 3Ω from ultra-small SC7/SOT3 packages making them ideal for mono/stereo headphone drivers in portable applications. These amplifiers have a 5MHz gain-bandwidth product and are guaranteed to deliver 5mA of output current while operating from a single supply of.7v to 5.5V. The MAX4336 and the MAX4338 have a shutdown/mute mode that reduces the supply current to.4µa per amplifier and places the outputs in a high-impedance state. The have 9dB power-supply rejection ratio (PSRR), eliminating the need for costly pre-regulation in most audio applications. Both the input voltage range and the output voltage swing include both supply rails, maximizing dynamic range. The MAX4335/MAX4336 single amplifiers are available in ultra-small 6-pin SC7 packages. The MAX4337/ MAX4338 dual amplifiers are available in an 8-pin SOT3 and a -pin µmax package, respectively. All devices are specified from -4 C to +85 C.

10 Applications Information Package Power Dissipation Warning: Due to the high-output-current drive, this op amp can exceed the absolute maximum power-dissipation rating. As a general rule, as long as the peak current is less than or equal to 5mA, the maximum package power dissipation will not be exceeded for any of the package types offered. There are some exceptions to this rule, however. The absolute maximum power-dissipation rating of each package should always be verified using the following equations. The following equation gives an approximation of the package power dissipation: ( ) θ P IC DISS V RMS I RMS COS where: VRMS = the RMS voltage from VCC to V when sourcing current = the RMS voltage from V to V EE when sinking current IRMS = the RMS current flowing out of or into the op amp and the load θ = the phase difference between the voltage and the current. For resistive loads, COS θ =. For example, the circuit in Figure has a package power dissipation of mw. V IN = V P-P C R R 5.5V MAX4335 MAX4336 3Ω Figure. A Circuit Example where the MAX4335/MAX4336 is Dissipating High Power V IN = V P-P C IN R R 5.5V MAX4335 MAX4336 C C V RMS ( V CC VDC) VPEAK = 55. V V 75. V =. 43VRMS I RMS IDC + I PEAK 75. V V/ 3Ω = + 3Ω = 8mARMS Therefore, P IC(DISS) = V RMS I RMS COS θ = mw Adding a coupling capacitor improves the package power dissipation because there is no DC current to the load, as shown in Figure. V RMS ( V CC VDC) VPEAK = 55. V V 75. V =. 43VRMS I + I PEAK RMS IDC = A + V / 3Ω = marms C C > π R L f L WHERE f L IS THE LOW-FREQUENCY CUTOFF Figure. A Circuit Example where Adding a Coupling Capacitor Greatly Reduces the Power Dissipation of Its Package Therefore, P IC(DISS) = V RMS I RMS COS θ = 45mW The absolute maximum power-dissipation rating of the package may be exceeded if the configuration in Figure is used with the MAX4335/MAX4336 amplifiers at a high ambient temperature of 79 C (.6mW/ C plus a derating of 3.mW/ C x 9 C = 47.9mW). Note that the 47.9mW just exceeds the absolute maximum power dissipation of 45mW for the 6-pin SC7 package. 3Ω
11 Single-Supply Speaker Driver The MAX4335/MAX4336 can be used as a single-supply speaker driver, as shown in the Typical Operating Circuit. Capacitor C is used for blocking DC (a.µf ceramic capacitor can be used). When choosing resistors R3 and R4, take into consideration the input bias current as well as how much supply current can be tolerated. Choose resistors R and R according to the amount of gain and current desired. Capacitor C3 ensures unity gain for DC. A µf electrolytic capacitor is suitable for most applications. The coupling capacitor C sets a low-frequency pole and is fairly large in value. For a 3Ω load, a µf coupling capacitor gives a low-frequency pole at 5Hz. The low-frequency pole can be set according to the following equation: ƒ = / π (R L C) Rail-to-Rail Input Stage Devices in the family of highoutput-current amplifiers have rail-to-rail input and output stages designed for low-voltage, single-supply operation. The input stage consists of separate NPN and PNP differential stages that combine to provide an input common-mode range that extends.5v beyond the supply rails. The PNP stage is active for input voltages close to the negative rail, and the NPN stage is active for input voltages near the positive rail. The switchover transition region, which occurs near V CC /, has been extended to minimize the slight degradation in common-mode rejection ratio caused by mismatch of the input pairs. Since the input stage switches between the NPN and PNP pairs, the input bias current changes polarity as the input voltage passes through the transition region. Match the effective impedance seen by each input to reduce the offset error caused by input bias currents flowing through external source impedances (Figures 3 and 5). High source impedances, together with input capacitance, can create a parasitic pole that produces an underdamped signal response. Reducing the input impedance or placing a small (pf to pf) capacitor across the feedback resistor improves response. The s inputs are protected from large differential input voltages by kω series resistors and back-to-back double diodes across the inputs (Figure 5). For differential voltages less than.v, input resistance is typically 5kΩ. For differential input voltages greater than.v, input resistance is approximately 8.4kΩ. The input bias current is given by the following equation: I BIAS = (V DIFF -.V) / 8.4kΩ R3 = R R R3 R Figure 3. Reducing Offset Error Due to Bias Current (Noninverting) R3 = R R R3 R Rail-to-Rail Output Stage The minimum output is within millivolts of ground for single-supply operation, where the load is referenced to ground (GND). Figure 6 shows the input voltage range and the output voltage swing of a MAX4335 connected as a voltage follower. The maximum output voltage swing is load dependent; however, it is guaranteed to be within 4mV of the positive rail () even with maximum load (3Ω to V CC /). Driving Capacitive Loads The have a high tolerance for capacitive loads. They are stable with capacitive loads up to pf. Figure 7 is a graph of the stable operating region for various capacitive loads vs. resistive loads. R R Figure 4. Reducing Offset Error Due to Bias Current (Inverting)
12 4.kΩ 4.kΩ Figure 5. Input Protection Circuit Figures 8 and 9 show the transient response with excessive capacitive loads (33pF), with and without the addition of an isolation resistor in series with the output. Figure shows a typical noninverting capacitive-load-driving circuit in the unity-gain configuration. The resistor improves the circuit s phase margin by isolating the load capacitor from the op amp s output. Power-Up and Shutdown/Mute Modes The MAX4336/MAX4338 have a shutdown option. When the shutdown pin (SHDN) is pulled low, supply current drops to.4µa per amplifier (VCC = 5V), the amplifiers are disabled, and their outputs are placed in a high-impedance state. Pulling SHDN high enables the amplifier. In the dual MAX4338, the two amplifiers shut down independently. Figure shows the MAX4336 s output voltage response to a shutdown pulse. The typically settle within 5µs after power-up (Figure ). Power Supplies and Layout The can operate from a single.7v to 5.5V supply. Bypass the power supply with a.µf ceramic capacitor in parallel with at least µf. Good layout improves performance by decreasing the amount of stray capacitance at the op amps inputs and outputs. Decrease stray capacitance by placing external components close to the op amps input/output pins, minimizing trace and lead lengths. Thermal Overload Protection The includes thermal overload protection circuitry. When the junction temperature of the device exceeds +4 C, the supply current drops to µa per amplifier (V CC = 5V) and the outputs are placed in a high-impedance state. The device returns to normal operation when the junction temperature falls to below + C. Short-Circuit Current Protection The incorporate a smart short-circuit protection feature. Figure 7 shows the output voltage region where the protection circuitry is active. A fault condition occurs when I > ma and V > V (sinking current) or when I > ma and (V CC - V ) > V (sourcing current). When a fault is detected, the short-circuit protection circuitry is activated and the output current is limited to ma, protecting the device and the application circuitry. When the smart short circuit is not active, the output current can safely exceed ma (see the Output Current vs. Output Voltage Graph in the Typical Operating Characteristics).
