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  
±1 LSB INL AND DNL  
The ADS7842 is a complete, 4-channel, 12-bit analog-  
to-digital converter (ADC). It contains a 12-bit, ca-  
pacitor-based, SAR A/D with a sample-and-hold am-  
plifier, 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 reso-  
lution from 24µV to 1.22mV. The ADS7842 is guar-  
anteed down to 2.7V operation.  
GUARANTEED NO MISSING CODES  
72dB SINAD  
LOW POWER: 2mW  
SSOP-28 PACKAGE  
Low power, high speed and an on-board multiplexer  
make the ADS7842 ideal for battery-operated sys-  
tems 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.
