7 Detailed Description

7.1 Overview

The AMC7836 device is a highly-integrated analog-monitoring and control solution capable of voltage and

temperature supervision. The AMC7836 device includes the following features:

•

Sixteen 12-bit digital-to-analog converters (DACs) with adjustable output ranges

–

Output ranges: –10 to 0 V, –5 to 0 V, 0 to 5 V, and 0 to 10 V

–

Auto-range detector on device power-up and reset events

–

The DACs power-on and clamp voltages can be pin-selected between AGND and a negative voltage

–

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

–

Sixteen bipolar inputs: –12.5 to 12.5 V input range

–

Five precision inputs with programmable threshold detectors: 0 to 5 V input range

–

Internal temperature sensor

•

Internal 2.5 V precision reference

•

Eight general purpose I/O (GPIO) ports

•

Communication with the device occurs through a 4-wire SPI-compatible interface supporting 1.8 to 5.5 V

operation

The AMC7836 device is characterized for operation over the temperature range of –40ºC to 125ºC which makes

the device suitable for harsh-condition applications. The device is available in a 10-mm × 10-mm 64-pin HTQFP

PowerPAD IC package.

The very high-integration of the AMC7836 device makes it an ideal all-in-one, low-cost, bias-control circuit for the

power amplifiers (PAs) 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 AMC7836 feature set is similarly beneficial in general-purpose monitor and control systems.
