The LMH32401RGT evaluation module (EVM) is a development platform for the LMH32401 differential-output transimpedance ampifier in the RGT package. The EVM features a transformer to convert the output to a 50-Ω single-ended connection for easy measurement with standard test equipement, and the option to convert to fully differential DC-coupled signals. The input is 50-Ω matched and configured by default to receive a voltage input that is converted to a current through a 2-kΩ resistor, but can be reconfigured to receive a true current input with optional photodiode bias connections on the back of the board.
LMH32401RGTEVM also includes easy-to-use jumpers to control the device gain, input bias current cancellation and shutdown functions.
