Product Summary

The ADS7842E 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 ADS7842E 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 ADS7842E is tested down to 2.7V operation. Low power, high speed, and an onboard multiplexer make the ADS7842E ideal for battery-operated systems such as portable, multi-channel dataloggers and measurement equipment.
