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 channel-count, additional features, or converter resolutions, Texas Instruments offers a complete family of analog monitor and control (AMC) products. For more information, go to www.ti.com/amc.
