TI AMC7820 Analog Monitoring and Control Circuit

Texas Instruments AMC7820 Analog Monitoring and Control Circuit includes an 8-channel, 12-bit analog-to-digital converter (ADC), three 12-bit digital-to-analog converters (DACs), nine operational amplifiers, a thermistor current source, an internal +2.5V reference, and an SPI™ serial interface. External reference may be applied. Typical power dissipation for the TI AMC7820 is 40mW. The unbuffered analog input range for the ADC is 0V to +5.0V, and the buffered analog common-mode input range is 0V to +3.8V. The analog output range for the DACs is 0V to +2.5V or 0V to +5.0V. TI AMC7820 Analog Monitoring and Control Circuit is ideal for multichannel applications where low power and small size are critical. AMC7820 is fully specified and tested over the -40°C to +85°C temperature range.
