12-Bit High Density Analog Monitor and Control (AMC) Solution - AMC7832


12-Bit High Density Analog Monitor and Control (AMC) Solution


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 http://www.ti.com/amc for more information.
