ALM2402F-Q1 Evaluation Module
1 Introduction
The ALM2402F-Q1 is an automotive-grade, dual high-voltage, high-current operational amplifier (op amp)
with protection features from Texas Instruments. For a full list of electrical characteristics for the
ALM2402F-Q1, see the
ALM2402F-Q1 Automotive, Dual Operational Ampilfier With High Current Output
data sheet .
2 EVM Circuit Description
This EVM is designed to provide access to the features, and measure the performance, of the ALM2402F-
Q1. By default, the ALM2402FQ1EVM has both amplifiers configured in the inverting configuration with a
gain of –2.5 V/V. A simplified schematic of the ALM2402FQ1EVM is displayed in
Figure 1 . For a full
schematic of the ALM2402FQ1EVM, see Section 7.1 .
