产品描述

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 differential analog input with an excellent common-mode signal rejection ratio of 85 dB, making the SM73201 suitable for noisy environments.

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 minimize power consumption by operating the analog portion of the ADC at a VA of +5V while interfacing with a +3.3V controller. The serial data output is binary 2's complement and is SPI compatible.

The performance of the SM73201 is specified over temperature 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 VSSOP 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 acquisition applications.
