ADS1626IPAPT

Analog To Digital Converters (ADC) Overview

The ADS1626IPAPT is a single-channel, 18-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a sigma-delta architecture and supports a sampling rate of 1.25 MSPS. The device features a parallel interface and accepts differential input signals. It operates with an analog supply voltage ranging from 4.75 V to 5.25 V and a digital supply voltage between 2.7 V and 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 93 dB and a power consumption of 520 mW. The component is housed in a 64-lead HTQFP package and functions within a temperature range of -40°C to +105°C.
