AMC7832
SLAS836 – MARCH 2014
8.1 Overview
The AMC7832 is a highly integrated analog monitoring and control solution capable of voltage and temperature
supervision. The AMC7832 includes the following:
• Twelve, 12-bit digital-to-analog converters (DACs) with adjustable output ranges
– Output ranges of 0 to +5-V, 0 to +10-V and -10 to 0-V
– The DAC power-on and clamp voltage can be terminal-selected between GND and AVSS
– The DACs can be configured to clamp automatically upon detection of an alarm event
• A multi-channel, 12-bit analog-to-digital converter (ADC) for voltage and temperature sensing
– 12 bipolar inputs: -12.5-V to +12.5-V input range
– 5 precision inputs with programmable threshold detectors: 0 to +5-V input range
– Internal temperature sensor
• Internal precision reference
• Eight General Purpose I/O (GPIO) ports
• Communication with the device is done through a 4-wire SPI compatible interface supporting +1.8-V to +5.5-V
operation
The AMC7832 is characterized for operation over the temperature range of -40ºC to 125ºC thus making it
suitable for harsh condition applications and is available in a 10mm x 10mm 64-terminal HTQFP PowerPAD
package.
The AMC7832’s high-integration 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.
