SBAS103C SEPTEMBER 2000 REVISED OCTOBER 2006  
12-Bit, 4-Channel Parallel Output Sampling  
ANALOG-TO-DIGITAL CONVERTER  
DESCRIPTION  
FEATURES  
SINGLE SUPPLY: 2.7V to 5V  
4-CHANNEL INPUT MULTIPLEXER  
UP TO 200kHz SAMPLING RATE  
FULL 12-BIT PARALLEL INTERFACE  
±1LSB INL AND DNL  
The 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.  
NO MISSING CODES  
72dB SINAD  
LOW POWER: 2mW  
SSOP-28 PACKAGE  
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.
