SM73201  
16-Bit, 50 to 250 kSPS, Differential Input, MicroPower ADC  
General Description  
Features  
The SM73201 is a 16-bit successive-approximation register  
(SAR) Analog-to-Digital converter (ADC) with a maximum  
sampling rate of 250 kSPS. The converter features a differ-  
ential analog input with an excellent common-mode signal  
rejection ratio of 85 dB, making the SM73201 suitable for  
noisy environments.  
Renewable Energy Grade  
Guaranteed performance from 50 to 250 kSPS  
Separate Digital Input/Output Supply  
True differential input  
External voltage reference range of +0.5V to VA  
Wide input common-mode voltage range of 0V to VA  
The SM73201 operates with a single analog supply (VA) and  
a separate digital input/output (VIO) supply. VA can range from  
+4.5V to +5.5V and VIO can range from +2.7V to +5.5V. This  
allows a system designer to maximize performance and min-  
imize power consumption by operating the analog portion of  
the ADC at a VA of +5V while interfacing with a +3.3V con-  
troller. The serial data output is binary 2's complement and is  
SPI™ compatible.  
SPI™/QSPI™/MICROWIRE™ compatible Serial  
Interface  
Operating temperature range of −40°C to +85°C

The performance of the SM73201 is guaranteed over tem-  
perature at clock rates of 1 MHz to 5 MHz and reference  
voltages of +2.5V to +5.5V. The SM73201 is available in a  
small 10-lead MSOP package. The high accuracy, differential  
input, low power consumption, and small size make the  
SM73201 ideal for direct connection to bridge sensors and  
transducers in battery operated systems or remote data ac-  
quisition applications.
