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,

Texas Instruments offers a complete family of Analog

Monitor and Control (AMC) products. Visit
