FEATURES  
DESCRIPTION  
The ADS7945/6 are 14-bit, 2 MSPS analog-to-digital  
23  
•
Sample Rate: 2 MSPS  
converters (ADCs), with differential and single-ended  
inputs, respectively. The devices operate at a 2  
MSPS sample rate with a standard 16-clock data  
frame. The devices feature both outstanding dc  
precision and excellent dynamic performance; the  
ADS7946 is pin-compatible with the 8/10/12-bit

–
SNR: 84 dB (ADS7945)  
No Missing Codes  
ADS7947/8/9 devices. The devices include  
a
INL: 1.5 LSB (max) (ADS7945)  
two-channel input multiplexer and low-power  
a
successive approximation register (SAR) ADC with  
an inherent sample-and-hold (S/H) input stage.  
Low Power:  
–
–
11.6 mW at 2 MSPS Operation  
Auto Power-Down at Lower Speeds:  
The ADS7945/6 support a wide analog supply range  
that allows the full-scale input range to extend to ±5 V  
differential or 5 V single-ended. A simple SPI™, with  
a digital supply that can operate as low as 1.65 V,  
allows for easy interfacing to a wide variety of digital  
controllers. Automatic power-down can be enabled  
when operating at slower speeds to dramatically  
reduce power consumption.

–
Analog: 2.7 V to 5.25 V  
Digital: 1.65 V to AVDD  
Offered in a tiny 3 mm × 3 mm QFN package, the  
ADS7945/6 are fully specified over the extended  
temperature range of –40°C to +125°C and are

Simple Serial Interface (SPI)  
Fully Specified from –40°C to +125°C  
Tiny Footprint: 3 mm × 3 mm QFN  
suitable for  
a wide variety of data acquisition  
applications where high performance, low power, and  
small package size are key.
