The AMC7924 is a highly integrated analog monitor and control device designed for high-density, general-purpose monitor and control systems. The AMC7924 includes 24 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 AMC7924 high level of integration significantly reduces component count and simplifies closed-loop system designs, thus making the device a great choice for high-density applications where board space is critical.

The device includes 24 dedicated ADC inputs and six flexible input/output (FlexIO) pins that can be configured as either additional analog inputs to the ADC or as GPIOs. Communication to the device is performed through a 4-wire, SPI-compatible interface.

The AMC7924 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 a large variety of transistor technologies, such as LDMOS, GaAs, and GaN. The AMC7924 feature set is similarly beneficial in general-purpose monitor and control systems.
