Single- and 4-Channel, 9 us, 10-Bit ADCs with On-Chip Temperature Sensor

GENERAL DESCRIPTION The AD7818 and AD7817 are 10-bit, single- and 4-channel A/D converters with on-chip temperature sensor that can operate from a single 2.7 V to 5.5 V power supply. Each part contains a 9 µs successive-approximation converter based around a capacitor DAC, an on-chip temperature
