General Description

The MAX44265 evaluation kit (EV kit) provides a proven

design to evaluate the MAX44265 low-power, MOS-input

operational amplifier (op amp) in a 6-bump wafer-level

package (WLP). The EV kit circuit is preconfigured as a

noninverting amplifier, but can easily be adapted to other

topologies by changing a few components. Low power,

low-input V

, and rail-to-rail input/output stages make

this device ideal for a variety of measurement applica-

tions. The component pads accommodate 0805 pack-

ages, making them easy to solder and replace. The EV

kit comes with a MAX44265EWT+ installed.

MAX44265 Evaluation Kit Evaluates: MAX44265 Quick Start Required Equipment • MAX44265 EV kit • +5V, 10mA DC power supply (PS1) • Precision voltage source • Digital multimeter (DMM) Procedure The EV kit is fully assembled and tested. Follow the steps below to verify board operation: Op-Amp Configurations The device is a single-supply op amp that is ideal for differential sensing, noninverting amplification, buffering, and filtering.

MAX44265 Evaluation Kit Evaluates: MAX44265 Lowpass Sallen-Key Filter To configure the Sallen-Key as a lowpass filter, populate the R2 and R8 pads with resistors and the C3 and C4 pads with capacitors. The corner frequency and Q are then given by: fC = 1 2π R2 × C3 × R8 × C4 Q= R2 × C3 × R8 × C4 C4(R2 + R8) Highpass Sallen-Key Filter To configure the Sallen-Key as a highpass filter, populate the C3 and C4 pads with resistors and the R2 and R8 pads with capacitors.
