1 9-346; Rev 2; / 2kHz, 4µA, Rail-to-Rail General Description The single MAX99/MAX99 and dual MAX992/ MAX993 operational amplifiers (op amps) feature a maximized ratio of gain bandwidth (GBW) to supply current and are ideal for battery-powered applications such as portable instrumentation, portable medical equipment, and wireless handsets. These CMOS op amps feature an ultra-low input-bias current of pa, railto-rail inputs and outputs, low supply current of 4µA, and operate from a single.8v to 5.5V supply. For additional power conservation, the MAX99/MAX993 feature a low-power shutdown mode that reduces supply current to na, and puts the amplifiers outputs in a high-impedance state. These devices are unity-gain stable with a 2kHz GBW product. The MAX99 is available in a 5-pin SC7 package. The MAX99 is available in tiny 6-bump WLP and a 6-pin SC7 packages. The MAX992 is available in an 8-pin SOT23 package, and the MAX993 is available in a - pin µmax package. All devices are specified over the -4 C to +85 C extended operating temperature range.

These CMOS devices consume an ultralow 4µA (typ) supply current and a 2µV (typ) offset voltage. For additional power conservation, the MAX99/MAX993 feature a low-power shutdown mode that reduces supply current to na (typ), and puts the amplifiers output in a high-impedance state. These devices are unity-gain stable with a 2kHz GBW product, driving capacitive loads up to 3pF. The capacitive load can be increased to 25pF when the amplifier is configured for a V/V gain. Rail-to-Rail Inputs and Outputs All of the MAX99 MAX993 amplifiers have a parallelconnected n- and p-channel differential input stage that allows an input common-mode voltage range that extends mv beyond the positive and negative supply rails, with excellent common-mode rejection. The MAX99 MAX993 are capable of driving the output to within 5mV of both supply rails with a kω load. These devices can drive a 5kΩ load with swings to within 6mV of the rails. Figure shows the output voltage swing of the MAX99 MAX993 configured as a unity-gain buffer powered from a single 3V supply. Low Input Bias Current The MAX99 MAX993 feature ultra-low pa (typ) input bias current. The variation in the input bias current is minimal with changes in the input voltage due to very high input impedance (in the order of GΩ). Applications Information Driving Capacitive Loads The MAX99 MAX993 amplifiers are unity-gain stable for loads up to 3pF. However, the capacitive load can be increased to 25pF when the amplifier is configured for a minimum gain of V/V. Applications that require greater capacitive-drive capability should use an isolation resistor between the output and the capacitive load (Figure 2). Also, in unity-gain applications with relatively small R L (approximately 5kΩ), the capacitive load can be increased up to 2pF. Power-Supply Considerations The MAX99 MAX993 are optimized for single.8v to 5.5V supply operation. A high amplifier power-supply 9

10 2kHz, 4µA, Rail-to-Rail MAX99 MAX993 rejection ratio of 95dB (typ) allows the devices to be powered directly from a battery, simplifying design and extending battery life. Power-Up Settling Time The MAX99 MAX993 typically require 5µs after power-up. Supply settling time depends on the supply voltage, the value of the bypass capacitor, the output impedance of the incoming supply, and any lead resistance or inductance between components. Op-amp settling time depends primarily on the output voltage and is slew-rate limited. Figure 3 shows the MAX99_ in a noninverting voltage follower configuration with the input held at midsupply. The output settles in approximately 8µs for V DD = 3V (see the Typical Operating Characteristics for power-up settling time). Shutdown Mode The MAX99/MAX993 feature active-low shutdown inputs. The MAX99/MAX993 enter shutdown in 2µs (typ) and exit in 3µs (typ). The amplifiers outputs are in a high-impedance state in shutdown mode. Drive SHDN low to enter shutdown. Drive SHDN high to enable the amplifier. The MAX993 dual-amplifier features separate shutdown inputs. Shut down both amplifiers for the lowest quiescent current. Power-Supply Bypassing and Layout To minimize noise, bypass V DD with a.µf capacitor to ground, as close to the pin as possible. Good layout techniques optimize performance by decreasing the amount of stray capacitance and inductance to the op amps inputs and outputs. Minimize stray capacitance and inductance by placing external components close to the IC. 3V V 3V V RAIL-TO-RAIL OUTPUT VOLTAGE RANGE 2µs/div Figure.
