DESCRIPTIONThe ADS7842 is a complete, 4-channel, 12-bit Analog-to-
Digital Converter (ADC). It contains a 12-bit, capacitor-
based, 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 equip-
ment. The ADS7842 is available in an SSOP-28 package
and is tested over the –40°C to +85°C temperature range.
