General Description
ADS7842 General Description
The ADS7842 is a complete, 4-channel, 12-bit analogto-digital converter (ADC). It contains a 12-bit, capacitor-based, SAR A/D with a sample-and-hold amplifier, interface for microprocessor use and parallel, three-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 guaranteed down to 2.7V operation.
Low power, high speed and an on-board multiplexer make the ADS7842 ideal for battery-operated systems such as portable, multi-channel dataloggers and measurement equipment. The ADS7842 is available in a SSOP-28 package and is guaranteed over the 40°C to +85°C temperature range.
