FEATURES  
DESCRIPTION  
The ADC122S625 is a dual 12-bit, 50 kSPS to 200  
kSPS simultaneous sampling Analog-to-Digital (A/D)  
converter. The analog inputs on both channels are  
sampled simultaneously to preserve their relative  
phase information to each other. The converter is

•
•
•
•
External Reference  
architecture where the differential nature of the  
analog inputs is maintained from the internal track-  
and-hold circuits throughout the A/D converter to  
provide excellent common-mode signal rejection. The  
ADC122S625 features an external reference that can  
be varied from 1.0V to VA.  
Wide Input Common-Mode Voltage Range  
Single High-Speed Serial Data Output  
Operating Temperature Range of −40°C to  
+105°C  
•
SPI™/ QSPI™/MICROWIRE/DSP Compatible  
Serial Interface  
The ADC122S625's serial data output is binary 2's  
complement and is compatible with several  
standards, such as SPI™, QSPI™, MICROWIRE™,  
and many common DSP serial interfaces. The serial  
clock (SCLK) and chip select bar (CS) are shared by  
both channels.

Data Acquisition Systems  
Medical Instruments  
Operating from a single 5V analog supply and a  
reference voltage of 2.5V, the total power  
consumption while operating at 200 kSPS is typically  
8.6 mW. With the ADC122S625 operating in power-  
down mode, the power consumption reduces to 2.6  
µW. The differential input, low power consumption,  
and small size make the ADC122S625 ideal for direct  
connection to sensors in motor control applications.
