ADS8401IPFBRG4

Analog To Digital Converters (ADC) Overview

The ADS8401IPFBRG4 is a 16-bit, 1.25 MSPS analog-to-digital converter (ADC) featuring a unipolar single-ended input range from 0 V to Vref. It integrates a 4.096-V internal reference and buffer within a 48-lead TQFP package. The device utilizes a capacitor-based successive approximation register (SAR) architecture with inherent sample-and-hold functionality. Key electrical parameters include a typical power dissipation of 155 mW at maximum throughput, a conversion time of 610 ns, and an acquisition time of 150 ns. It supports both full 16-bit and split 8-bit parallel data bus transfers.
