3 Description
The AMC7932 is a highly integrated analog monitor
and control device designed for high-density, generalpurpose
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-todigital
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 a great
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 AMC7932 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.
