ADS8383IPFBT

Analog To Digital Converters (ADC) Overview

The ADS8383IPFBT is an 18-bit, 500-kSPS successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a unipolar input range and includes an onboard reference buffer. The device supports flexible data transfer via an 8-, 16-, or 18-bit parallel interface. Powered by a 5-V analog supply (+VA) and a 2.95-V to 5.25-V digital supply (+VBD), it dissipates approximately 110 mW at maximum throughput. The component is housed in a 48-lead TQFP package and operates within an industrial temperature range of −40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix against the manufacturer's Package Option Addendum to confirm the exact transport media and quantity. The IPFBT designation indicates a tape and reel configuration. Confirm that the ordering information matches current availability on the official Texas Instruments website, as manufacturing status can change without immediate notification.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS8383I variant if 17-bit performance is sufficient, or the ADS8383IB variant for full 18-bit integral linearity specifications. Ensure the application requires a unipolar input voltage range compatible with the reference voltage. Verify that the host system can accommodate the required 48-pin TQFP footprint and the necessary parallel control signals such as CONVST, CS, and RD.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS838x family of high-resolution, high-speed ADCs from Texas Instruments. It utilizes a charge redistribution SAR architecture with inherent sample-and-hold capabilities. The device is designed for applications requiring precise data acquisition with minimal processing delay, distinguishing it from lower-resolution or serial-interface alternatives in the broader portfolio.
