ADS8344E/2K5G4

Analog To Digital Converters (ADC) Overview

The ADS8344E/2K5G4 is a low-power, high-precision analog-to-digital converter manufactured by Texas Instruments. It features an 8-channel input architecture with a 16-bit resolution and a sampling rate of 100 kS/s. The device utilizes a successive approximation register (SAR) structure and supports both pseudo-differential and single-ended input types. It operates on dual power supplies ranging from 2.7 V to 5.25 V for both analog and digital domains. Key performance metrics include a signal-to-noise and distortion ratio (SINAD) of 86 dB, differential nonlinearity (DNL) of ±2 LSB, and integral nonlinearity (INL) of 12 LSB. The component is housed in a QSOP-20 package and functions within a temperature range of -40°C to +85°C.
