10位ADC控制系统数模转换器温度传感器和GPIOs数据表ad7292

　　The AD7292 contains all the functionality required for generalpurpose 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 singleended 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.
