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 V_A

Wide input common-mode voltage range of 0V to V_A

The SM73201 operates with a single analog supply (V_A) and

a separate digital input/output (V_IO) supply. V_Acan range from

+4.5V to +5.5V and V_IOcan 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 V_Aof +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.
