AMC7820 说明

The AMC7820 is a complete analog monitoring and control circuit that 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 SPITM serial interface. External reference may be applied. Typical power dissipation is 40mW. For the ADC, the unbuffered analog input range is 0V to +5.0V, and the buffered analog common-mode input range is 0V to +3.8V. For the DACs, the analog output range is 0V to +2.5V or 0V to +5.0V.

The AMC7820 is ideal for multichannel applications where low power and small size are critical. The AMC7820 is available in a TQFP-48 package and is fully specified and tested over the –40°C to +85°C temperature range.
