ADS7841  
SBAS084B – JULY 2001  
12-Bit, 4-Channel Serial Output Sampling  
ANALOG-TO-DIGITAL CONVERTER  
DESCRIPTION  
FEATURES  
ꢀ SINGLE SUPPLY: 2.7V to 5V  
The ADS7841 is a 4-channel, 12-bit sampling Analog-to-  
Digital Converter (ADC) with a synchronous serial inter-  
face. The resolution is programmable to either 8 bits or 12  
bits. Typical power dissipation is 2mW at a 200kHz through-  
put rate and a +5V supply. The reference voltage (VREF) can  
be varied between 100mV and VCC, providing a correspond-  
ing input voltage range of 0V to VREF. The device includes  
a shutdown mode which reduces power dissipation to under  
15µW. The ADS7841 is tested down to 2.7V operation.  
ꢀ 4-CHANNEL SINGLE-ENDED OR  
2-CHANNEL DIFFERENTIAL INPUT  
ꢀ UP TO 200kHz CONVERSION RATE  
ꢀ ±1LSB MAX INL AND DNL  
ꢀ NO MISSING CODES  
ꢀ 72dB SINAD  
ꢀ SERIAL INTERFACE  
Low power, high speed, and on-board multiplexer make the  
ADS7841 ideal for battery-operated systems such as per-  
sonal digital assistants, portable multi-channel data loggers,  
and measurement equipment. The serial interface also pro-  
vides low-cost isolation for remote data acquisition. The  
ADS7841 is available in a DIP-16 or a SSOP-16 package  
and is specified over the –40°C to +125°C(1) temperature  
range.
