ADS8320EB/250G4

Analog To Digital Converters (ADC) Overview

The ADS8320EB/250G4 is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.25 V for both analog and digital domains. The device supports sampling rates up to 100 kS/s with a serial interface compatible with standard SPI protocols. It features differential or single-ended input configurations and utilizes an external reference. Key performance metrics include a signal-to-noise ratio of 92 dB, a power consumption of 4.5 mW at typical operation, and a maximum power dissipation of 8.5 mW. The component is housed in an 8-pin VSSOP package and functions within a temperature range of -40°C to +85°C.
