ADS7841  
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  
interface. The resolution is programmable to either 8  
or 12 bits. Typical power dissipation is 2mW at a  
200kHz throughput rate and a +5V supply. The refer-  
ence voltage (VREF) can be varied between 100mV and  
VCC, providing a corresponding input voltage range of  
0V to VREF. The device includes a shutdown mode  
which reduces power dissipation to under 15µW. The  
ADS7841 is guaranteed down to 2.7V operation.  
4-CHANNEL SINGLE-ENDED OR  
2-CHANNEL DIFFERENTIAL INPUT  
UP TO 200kHz CONVERSION RATE  
±1 LSB MAX INL AND DNL  
GUARANTEED NO MISSING CODES  
72dB SINAD  
SERIAL INTERFACE  
16-PIN PDIP OR 16-LEAD SSOP PACKAGE  
ALTERNATE SOURCE FOR MAX1247  
Low power, high speed, and on-board multiplexer  
make the ADS7841 ideal for battery operated systems  
such as personal digital assistants, portable multi-  
channel data loggers, and measurement equipment.  
The serial interface also provides low-cost isolation  
for remote data acquisition. The ADS7841 is available  
in a 16-pin PDIP or a 16-lead SSOP package and is  
guaranteed over the –40°C to +85°C temperature range.
