Texas Instruments AMC7820

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 spi 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 40c to +85c temperature range.
