ADS8320SHKJ

Analog To Digital Converters (ADC) Overview

The ADS8320SHKJ is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single differential input channel and supports sampling rates up to 100 kSPS. The device operates on dual power supplies ranging from 2.7 V to 5.25 V for both analog and digital domains, consuming approximately 4.5 mW of typical power. It utilizes an external reference architecture and communicates via a serial SPI interface. Key performance metrics include a signal-to-noise ratio of 92 dB, a differential nonlinearity of ±2 LSB, and an integral nonlinearity of ±0.012% FSR. The component is housed in a VSSOP-8 package and functions within a temperature range of -40°C to +85°C.
