ADS8401IPFBTG4

Analog To Digital Converters (ADC) Overview

The ADS8401IPFBTG4 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 maximum conversion time of 610 ns, an acquisition time of 150 ns, and a typical power dissipation of 155 mW at full throughput. It operates over an industrial temperature range of –40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS adherence per Texas Instruments standards. Confirm the PFBT transport media specifies tape and reel packaging containing 250 units. Ensure the ordering code matches the specific linearity grade required for the application.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a unipolar input range and integrated reference are required. The ADS8401I variant offers ±6 LSB integral linearity, while the ADS8401IB provides tighter ±3.5 LSB accuracy. Ensure the digital supply voltage (+VBD) meets the minimum differential requirement relative to the analog supply (+VA).

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8401 family of micro-power sampling ADCs. The IPFBT designation identifies the Industrial temperature grade (-40°C to 85°C), TQFP-48 package, and Tape & Reel shipping format.
