The AMC7823 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. The AMC7823 has an internal programmable reference (+2.5V or +1.25V), and an SPI serial interface. An external reference can be used as well. Typical power dissipation is 100mW. The analog input range is 0V to +5V, and the analog output range is 0V to +2.5V or 0V to +5V. The AMC7823 is ideal for multichannel applications where low power and small size are critical. The AMC7823 is available in a 40-lead QFN package and is fully specified over the -40C to +85C temperature range.
