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.
