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  
14-Bit, Pin-Compatible with 8/10/12-bit  
ADS7947/8/9 Family (ADS7946)  
Outstanding Performance:  
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.  
7.2 mW at 500 kSPS  
1.4 mW at 100 kSPS  
0.3 mW at 20 kSPS  
Wide Supply Range:  
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.
