8 Detailed Description

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.
