3 Description
The AMC7832 is a highly integrated, low-power,
analog monitoring and control solution that includes a 17-channel, 12-bit analog-to-digital converter (ADC)
with programmable alarms, twelve 12-bit digital-to-
analog converters (DACs) with output ranges of either
0 to +5-V, 0 to +10-V or -10 to 0-V, eight GPIOs,
internal reference and a local temperature sensor channel. The AMC7832 high level of integration
significantly reduces component count and simplifies
closed-loop system designs.
The AMC7832 is ideal for multichannel applications
where board space, size, and low power are critical.
The AMC7832’s low power, high-integration and wide
operating temperature range make it an ideal all-in•
one, low-cost, bias control circuit for the power amplifiers (PA) found in multi-channel RF
communication systems. The flexible DAC output
ranges allow the device to be used as a biasing
solution for a large variety of transistor technologies
such as LDMOS, GaAs and GaN. The AMC7832
feature set is similarly beneficial in general purpose
monitor and control systems.
For applications that require a different channel
count, additional features, or converter resolutions,

Monitor and Control (AMC) products. Visit
