1 Introduction
1.1 Using the ALM2402Q1EVM
The ALM2402Q1EVM is intended to be very simple. Test points throughout the board allow a connection
to every pin of the device. The board is full of empty resistor footprints in order to allow the customer full
customization of their ALM2402Q1 test circuit. For most paths, non-populated resistor footprints are in
parallel to allow for any variation in resistor sizes the customer may use. There are many more options for
load resistor footprint sizes, as the ALM2402Q1 is able to output hundreds of mA. For small resistive
loads, use the larger available footprints and populate with resistors with higher power dissipation ratings.
By default, the ALM2402Q1EVM is configured as a unity gain amplifier for both of the amplifiers inside the
ALM2402Q1.
See Figure 1 for the full schematic, and Figure 2 for the board schematic explaining which resistors are
not populated.
