Evaluates: MAX44290

MAX44290 Evaluation Kit

General Description

The MAX44290 evaluation kit (EV kit) provides a proven

design to evaluate the MAX44290 low-offset, low-power,

rail-to-rail I/O operational amplifier in a 6-pin wafer-level

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

noninverting amplifiers, but can be adapted to other

topologies by changing a few components.

The EV kit comes with a MAX44290ANT+ installed.

Features

● Accommodates Multiple Op Amp Configurations

● Component Pads Allow for Sallen-Key Filter

● Accommodates Easy-to-Use Components

● Proven PCB Layout

● Fully Assembled and Tested

Quick Start

Required Equipment

● MAX44290 EV kit

● +1.8V to +5.5V, 10mA DC power supply

● Precision voltage source

● Digital multimeter

Procedure

The EV kit is fully assembled and tested. Follow the steps

below to verify board operation:

1) Verify that all jumpers (JU1–JU3) are in their default

positions, as shown in Table 1.

2) Set the power supply to +5V. Connect the positive

terminal to GND.

3) Connect the positive terminal of the precision voltage

source to INP. Connect the negative terminal of the

precision voltage source to GND. INM is already

connected to GND through jumper JU1.

4) Connect the DMM to monitor the voltage on OUT.

With the 10kΩ feedback resistors and 1kΩ series

resistors, the gain of the noninverting amplifier is

+11V/V.

5) Turn on the power supply.

6) Apply 100mV from the precision voltage sources.

Observe the output at OUT on the DMM that reads

approximately +1.1V.
