The ADS7842 is a complete, 4-channel, 12-bit Analog-to-Digital Converter (ADC). It contains a 12-bit, capacitorbased, Successive Approximation Register (SAR) ADC with a sample-and-hold amplifier, interface for microprocessor use, and parallel, 3-state output drivers. The ADS7842 is specified at a 200kHz sampling rate while dissipating only 2mW of power. The reference voltage can be varied from 100mV to VCC with a corresponding LSB resolution from 24µV to 1.22mV. The ADS7842 is tested down to 2.7V operation.

Low power, high speed, and an onboard multiplexer make the ADS7842 ideal for battery-operated systems such as portable, multi-channel dataloggers and measurement equipment. The ADS7842 is available in an SSOP-28 package and is tested over the -40°C to +85°C temperature range.
