Texas Instruments AMC7932 12-Bit Analog Monitor & Controller

Texas Instruments AMC7932 12-Bit Analog Monitor and Controller is a highly integrated analog monitor and control device designed for high-density, general-purpose monitor and control systems. The AMC7932 includes 32 12-bit digital-to-analog converters (DACs) with programmable output ranges. The device also incorporates a multiplexed, 12-bit analog-to-digital converter (ADC) with programmable threshold detectors, a temperature sensor, and an internal reference. The AMC7932 high level of integration significantly reduces component count and simplifies closed-loop system designs, thus making it an excellent choice for high-density applications where board space is critical.

The device includes flexible input/output (FlexIO) pins that can be configured as either analog inputs to the ADC or as GPIOs with two available options: AMC7932 (six FlexIO pins) and AMC7932F (five FlexIO pins). Communication to the device is performed through a 3-wire (AMC7932) or 4-wire (AMC7932F) SPI-compatible interface. The Texas Instruments AMC7932's high integration and wide operating temperature range make the device an excellent choice as an all-in-one, bias-control circuit for the power amplifiers (PA) found in multichannel RF communication systems. The flexible DAC output ranges and built-in sequencing features allow the device to be used as a biasing controller for various transistor technologies, such as LDMOS, GaAs, and GaN.
