ADS7816  
12-Bit High Speed Micro Power Sampling  
ANALOG-TO-DIGITAL CONVERTER  
FEATURES  
DESCRIPTION  
200kHz SAMPLING RATE  
The ADS7816 is a 12-bit, 200kHz sampling analog-  
to-digital converter. It features low power operation  
with automatic power down, a synchronous serial  
interface, and a differential input. The reference volt-  
age can be varied from 100mV to 5V, with a corre-  
sponding resolution from 24µV to 1.22mV.  
MICRO POWER:  
1.9mW at 200kHz  
150µW at 12.5kHz  
POWER DOWN: 3µA Max  
8-PIN MINI-DIP, SOIC, AND MSOP  
DIFFERENTIAL INPUT  
Low power, automatic power down, and small size  
make the ADS7816 ideal for battery operated systems  
or for systems where a large number of signals must be  
acquired simultaneously. It is also ideal for remote  
and/or isolated data acquisition. The ADS7816 is  
available in an 8-pin plastic mini-DIP, an 8-lead SOIC,  
or an 8-lead MSOP package.
