ADS8343E/2K5

Analog To Digital Converters (ADC) Overview

The ADS8343E/2K5 is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features four differential or eight single-ended input channels with a maximum sampling rate of 100 kSPS. The device operates on a single supply voltage ranging from 2.7 V to 5.25 V for both analog and digital domains. It utilizes an external reference voltage and communicates via a standard SPI-compatible serial interface. Key performance metrics include a differential nonlinearity (DNL) of ±2 LSB, integral nonlinearity (INL) of ±8 LSB, and a signal-to-noise and distortion ratio (SINAD) of 85 dB. The component is housed in a 16-SSOP package and supports an operating temperature range from -40°C to +85°C.
