AMC7823

用于模拟监控和控制的集成多通道 ADC 和 DAC

The is a complete analog monitoring and control circuit that includes an 8-channel, 12-bit analog-to-digital converter ADC, eight 12-bit digital- to-analog converters DACs, four analog input out-of-range alarms, and six GPIOs to monitor analog signals and control external devices. Also, the AMC7823 has an internal sensor to monitor chip temperature, and a precision current source to drive remote thermistors, or RTDs, to monitor remote temperatures.
