ADS7854IPW

Analog To Digital Converters (ADC) Overview

The ADS7854IPW is a dual-channel, 14-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 1 MSPS and supports differential input configurations. The device features an SPI-compatible digital interface and requires an analog supply voltage between 4.5 V and 5.5 V, alongside a digital supply ranging from 1.65 V to 5.5 V. Key performance metrics include a signal-to-noise ratio of 88 dB and a total power dissipation of approximately 45 mW to 50 mW. It functions within a temperature range of -40°C to +125°C and is housed in a TSSOP-16 surface-mount package.
