The AD7292 is a single-chip solution that combines all the features needed for general-purpose analog signal monitoring and control of external devices. The AD7292 features an 8-channel 10-bit SAR DAC, four 10-bit DACs, an internal temperature sensor with an accuracy of ±1°C, and 12 GPIOs to assist with system monitoring and control.
Among them, the 10-bit, high-speed, low-power successive approximation register (SAR) ADC is designed to monitor a wide range of single-ended input signals. It also supports differential operation, which can be configured as differential pairs by configuring VIN0 and VIN1.
The AD7292 offers a register-programmable ADC sequencer with a choice of programmable channel sequences for conversion.
Four 10-bit digital-to-analog converters (DACs) provide outputs from 0 V to 5 V; An internal high-precision 1.25 V reference provides an independently buffered reference for the ADC and DAC.
It has a built-in high-precision bandgap temperature sensor that is monitored and digitized by a 10-bit ADC to provide a resolution of 0.03125°C. The AD7292 also has built-in limits and alarms.
The AD7292 is a highly integrated solution in a 36-pin LFCSP package with an operating temperature range of −40°C to +125°C.
