1 General Description The MAX40088 evaluation kit (EV kit) is a fully assembled and tested circuit board that contains all the components necessary to evaluate both MAX40075 and MAX40088 ICs. The MAX40088 EV kit printed circuit board (PCB) comes installed with MAX40088AUT+ in 6-SOT package. The device is a rail-to-rail output op amp offering 0MHz Gain Bandwidth product (MAX40075) and 4MHz Gain Bandwidth product (MAX40088). The EV kit operates from a single.7v to 5.5V DC power supply or from ±.5V to ±.75V split supply. Features +.7V to +5.5V Supply Voltage Range across V DD and V SS 4MHz Gain Bandwidth Product (MAX40088) 0MHz Gain Bandwidth Product (MAX40075) Ultra-Low Distortion (0.000% with kω load) Proven PCB Layout Fully Assembled and Tested Ordering Information appears at end of data sheet. Quick Start Required Equipment Before beginning, the following equipment is needed: MAX40088 EV kit.7v to 5.5V, 00mA DC power supply Precision voltage calibrator Digital multimeter Procedure The EV kit is fully assembled and tested. Follow the steps below to verify board operation. Caution: Do not turn on power supplies until all connections are completed and turn on V DD, V SS supplies before turning on voltage calibrator on the input pins. ) Make sure JU jumper is uninstalled and JU jumper is in - position before applying supply voltage. ) Connect positive terminal of the +5V supply to the test point and the GND terminal of supply to the GND test point. Make sure JU is in - position and JU4 is un-installed. JU4 is opened if split supply operation is desired. ) Connect the positive terminal of the precision voltage calibrator to the INP/TP test point. 4) Connect the DMM to monitor the voltage on the OUTA/TP test point. 5) Turn on the 5V power supply connected to test point, turn on the precision voltage calibrator on INP/TP test point and set 0.V. Observe the output at the OUTA/TP test point on the DMM. DMM should read approximately V. Also, vary IN+ voltage between 0V to 0.45V and see if DMM on OUTA test point is showing a gained up by voltage by 0V/V to the voltage applied on INP test point. Once above step is confirmed, EV kit is tested for functionality ; Rev 0; 8/7

2 Detailed Description of Hardware The MAX40088 EV kit contains the MAX40088 IC, which is rail-to-rail output op amps with low noise and wide bandwidth in 6-SOT package. The EV kit operates from a single.7v to 5.5V DC power supply. The EV kit is meant to work using split supplies as well where the voltage between V DD and V SS is +.7V to +5.5V. Default Application Circuit The EV kit comes preconfigured in a Non-Inverting amplifier configuration with Gain set as 0V/V. Op Amp Configurations The EV kit provides flexibility to easily reconfigure the op amp into any of the three common circuit topologies: inverting amplifier, non-inverting amplifier and Differential amplifier. These configurations are described in the next few sections. Noninverting Configuration The MAX40088 EV kit comes preconfigured as a noninverting amplifier. The gain is set by the ratio of R8 and R9. The MAX40088 EV kit comes preconfigured for a gain of 0. The output voltage for the non-inverting configuration is given by the equation below: R8 VOUTA = + VINP R9 Inverting Configuration To configure the EV kit as an inverting amplifier, remove the shunt - on JU and install a shunt on jumper JU on position - and feed an input signal on the INM pad. R8 VOUTA = VINM R9 Differential Amplifier To configure the MAX40088 EV kit as a differential amplifier, replace R, R, R8, and R9 with appropriate resistors. When R = R8 and R = R9, the CMRR of the differential amplifier is determined by the matching of the resistor ratios R/R and R8/R9. V OUTA = GAIN(V INP - V INM ) where R8 R GAIN = = R9 R Transimpedance Amplifier To configure the MAX40088 EV kit as a transimpedance amplifier (TIA), short jumper JU on -, replace R, R9 with a 0 ohm resistor and populate R8 pad with 00kΩ resistor. The output voltage of the TIA is the input current multiplied by the feedback resistor: V OUT = (I INM + I BIAS- ) x R8 + V OS where IINM is the input current source applied at the INM test point, IBIAS- is the input bias current into IN- pin, and V OS is the input offset voltage of the op amp. Use capacitor C to stabilize the op amp by rolling off high-frequency gain due to a large cable capacitance if desired. Capacitive Loads Some applications require driving large capacitive loads. To improve stability of the amplifier in such cases, replace R with a suitable resistor value to improve amplifier phase margin. Table. Default Jumper Settings JUMPER JU JU JU JU4 *Default position.
