MAX9617 Evaluation Kit Evaluates: MAX9617 General Description Features The MAX9617 evaluation kit (EV kit) provides a proven S Accommodates Multiple Op-Amp Configurations design to evaluate the MAX9617 low-power, zero-drift S Component Pads Allow for Sallen-Key Filter operational amplifier (op amp) in a 6-pin SC70 pack- S Rail-to-Rail Inputs/Outputs age. The EV kit circuit is preconfigured as a noninverting S Accomodates Easy-to-Use 0805 Components amplifier, but can easily be adapted to other topologies by changing a few components. Low power, zero drift, S Proven PCB Layout input offset voltage, and rail-to-rail input/output stages S Fully Assembled and Tested make this device ideal for a variety of low-frequen- cy measurement applications. The component pads accommodate 0805 packages, making them easy to solder and replace. The MAX9617 EV kit comes with a Ordering Information MAX9617AXT+ installed. PART TYPE MAX9617EVKIT+ EV Kit +Denotes lead(Pb)-free and RoHS compliant.

With the 10kI feedback resistor (R5) and 1kI Digital multimeter (DMM) series resistor (R1), the gain is +11 (noninverting con- figuration). Procedure 6) Turn on the +5V power supply. The MAX9617 EV kit is fully assembled and tested. 7) Apply 100mV from the precision voltage source. Follow the steps below to verify board operation: Observe the output at OUTA (TP7) on the DMM. 1) Verify that the jumpers are in their default position, as OUTA should read approximately +1.1V. shown in Table 1. 8) Apply 400mV from the precision voltage source. 2) Connect the positive terminal of the +5V supply to OUTA should read approximately +4.4V. VDD (TP1) and the negative terminal to GND (TP2) and VSS (TP3). Table 1. MAX9617 EV Kit Jumper Descriptions (JU1JU5) JUMPER SHUNT POSITION DESCRIPTION 1-2* Connects IN- to R1.
