Package
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 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 AMC7836
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. For more
