AD7294 Datasheet Dac/adc Temperature Sensor And Current Sense

Manufacturer: Analog Devices

Overview: .. 12-Bit, Multichannel, DAC/ADC Temperature Sensor and Current Sense for Monitor and Control Applications Preliminary Technical.

General Description

The AD7294 contains all the functions required for generalpurpose monitoring and control of current, voltage, and temperature integrated into a single-chip solution.

The part includes low voltage (±200 mV) analog-input sense amplifiers for current monitoring across shunt resistors, temperature-sense inputs, and four unmitted analog input channels multiplexed into a 200 kSPS SAR ADC.

An internal low ppm reference is provided to drive both the DAC and ADC.
