ADS8556IPM

Analog To Digital Converters (ADC) Overview

The ADS8556IPM is a six-channel, simultaneous-sampling analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 16-bit resolution and operates at a sampling rate of 630 kSPS. The device utilizes a successive approximation register (SAR) architecture with single-ended inputs. It supports both parallel and serial interfaces for data output. The analog supply voltage ranges from 4.5 V to 5.5 V, while the digital supply voltage ranges from 2.7 V to 5.5 V. Key performance metrics include a signal-to-noise ratio (SNR) of 91.5 dB, differential nonlinearity (DNL) of -1/2 LSB, and integral nonlinearity (INL) of +/- 4 LSB. It functions within a temperature range of -40°C to +125°C and is housed in an LQFP-64 package.

Analog To Digital Converters (ADC) Feature Summary
