ADS8371IBPFBR

Analog To Digital Converters (ADC) Overview

The ADS8371IBPFBR is a 16-bit, 750-kSPS successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a unipolar input range of 0 V to 4.096 V and operates with an analog supply voltage (+VA) of 4.75 V to 5.25 V and a buffer supply (+VBD) of 2.7 V to 5.25 V. The device achieves a signal-to-noise ratio (SNR) of 88 dB and a spurious-free dynamic range (SFDR) of 110 dB. It integrates an onboard reference buffer and conversion clock, dissipating approximately 130 mW at full throughput. The component utilizes a flexible 8- or 16-bit parallel interface and is housed in a 48-pin TQFP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'PFB' corresponds to the 48-pin TQFP package and 'R' indicates tape and reel packaging. Confirm the 'I' suffix denotes the industrial temperature range (-40°C to +85°C). Ensure the specific lot matches the datasheet revision SLAS390A for accurate electrical parameter validation.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a high-speed, 16-bit SAR ADC with a parallel interface is required. It is directly pin-compatible with the ADS8381 and ADS8383 series. Consider the 8-bit bus option using two read cycles if system bandwidth allows. Verify that the external reference voltage falls within the 2.5 V to 4.2 V range for optimal performance.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS8371 family of high-speed, low-power analog-to-digital converters. It is characterized for operation over the industrial temperature range of -40°C to +85°C. The device architecture relies on charge redistribution with inherent sample-and-hold functionality, distinguishing it from pipeline or sigma-delta architectures.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8371 is explicitly documented as being directly pin-compatible with the ADS8381 and ADS8383 models. These devices share the same 48-pin TQFP footprint and interface logic, facilitating direct substitution in existing designs without PCB layout modifications.
