AD7292:  10-Bit Monitor & Control System with ADC, DACs, Temperature Sensor and GPIOs

Product Details

Product Status:Recommended for New Designs

The AD7292 contains all the functionality required for general-purpose monitoring of analog signals and control of external devices, integrated into a single-chip solution. The AD7292 features an 8-channel, 10-bit SAR ADC, four 10-bit DACs, a ±1°C accurate internal temperature sensor, and 12 GPIOs to aid system monitoring and control.

The 10-bit, high speed, low power successive approximation register (SAR) ADC is designed to monitor a variety of single-ended input signals. Differential operation is also available by configuring VIN0 and VIN1 to operate as a differential pair.

The AD7292 offers a register programmable ADC sequencer, which enables the selection of a programmable sequence of channels for conversion.

Four 10-bit digital-to-analog converters (DACs) provide outputs from 0 V to 5 V. An internal, high accuracy, 1.25 V reference provides a separately buffered reference source for both the ADC and the DACs.

A high accuracy band gap temperature sensor is monitored and digitized by the 10-bit ADC to give a resolution of 0.03125°C. The AD7292 also features built-in limit and alarm functions.

The AD7292 is a highly integrated solution offered in a 36-lead LFCSP package with an operating temperature range of −40°C to +125°C.
