3 Description

The AMC7836 is a highly-integrated, low-power,

analog monitoring and control solution. The device

includes a 21-channel, 12-bit analog-to-digital

converter (ADC), sixteen 12-bit digital-to-analog

converters (DACs) with programmable output ranges,

eight GPIOs, an internal reference, and a local

temperature-sensor channel. The high level of

integration significantly reduces component count and

simplifies closed-loop system designs making it ideal

for multichannel applications where board space,

size, and low-power are critical.

The low-power, very high-integration and wide

operating-temperature range of the device make it

suitable as an all-in-one, low-cost, bias-control circuit

for the power amplifiers (PA) found in multichannel

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 AMC7836

feature set is similarly beneficial in general-purpose

monitor and control systems.

For applications that require a different channelcount,

additional features, or converter resolutions,

Texas Instruments offers a complete family of analog

monitor and control (AMC) products. For more
