AMC7834 Evaluation Module
1 Overview
This EVM features the AMC7834 device, a highly integrated, low-power, analog monitoring and control
solution for power amplifier biasing capable of current, temperature, and voltage supervision. The
AMC7834 integrates a multi-channel (12-bit) ADC, 8 (12-bit) DACs, and four high-side current sense
amplifiers supporting common mode voltages from +4-V up to +60-V into a single device. The DACs
include a flexible output range that allows the device to be fully compatible with a large array of biasing
technologies, such as LDMOS, GaAs, and GaN. The device also features 4 GPIO, out-of-range alarms,
an internal reference, and a low-power, SPI compatible interface.

The 24-V wall adapter is not included with the evaluation module (EVM). Optionally, a 24-V (750-mA)
center-positive wall adapter can be separately purchased to interface to the onboard 2.1 x 5.5-mm DC
jack. In the case that a wall adapter is not available, external terminal blocks are included, which can
interface with external supplies.
