FEATURES  
DESCRIPTION  
3-MHz Sample Rate, 12-Bit Resolution  
Zero Latency  
The ADS7882 is a 12-bit 3-MSPS A-to-D converter  
with 2.5-V internal reference. The device includes a  
capacitor based SAR A/D converter with inherent  
sample and hold. The device offers a 12-bit parallel  
interface with an additional byte mode that provides  
easy interface with 8-bit processors. The device has  
a pseudo-differential input stage.  
Unipolar, Pseudo Differential Input, Range:  
0 V to 2.5 V  
High-Speed Parallel Interface  
69.5 dB SNR at 100 kHz I/P  
Power Dissipation 85 mW at 3 MSPS  
Nap Mode (10 mW Power Dissipation)  
Power Down (10 µW)  
The –IN swing of ±200 mV is useful to compensate  
for ground voltage mismatch between the ADC and  
sensor and also to cancel common-mode noise. With  
nap mode enabled, the device operates at lower  
power when used at lower conversion rates. The  
device is available in 48-pin TQFP package.
