AMC7832 Analog Monitor and Control Solution


TI's solution reduces component count and simplifies closed-loop system designs

Texas Instruments' 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's high level of integration significantly reduces component count and simplifies closed-loop system designs.

The AMC7832 is ideal for multi-channel 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.
