ADS5221PFBT

Analog To Digital Converters (ADC) Overview

The ADS5221PFBT is a 12-bit, 65MSPS pipeline analog-to-digital converter (ADC) from Texas Instruments. It operates on a single +3.3V supply and dissipates 285mW. The device features a high signal-to-noise ratio of 70dB and an spurious-free dynamic range of 88dBFS at 9.7MHz. It supports both single-ended and fully differential analog inputs with a selectable full-scale range of 1V to 2V peak-to-peak. The ADC includes digital error correction logic for improved linearity and offers flexible duty cycle adjustment circuitry. It is housed in a TQFP-48 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix PFBT corresponds to the tape and reel packaging quantity of 250 units as listed in the manufacturer's documentation. Confirm that the component meets RoHS standards and check for any availability constraints or end-of-life notices associated with this specific part number before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS5221PFBT when a 12-bit resolution and 65MSPS speed are required within a single +3.3V supply constraint. Ensure the application can accommodate the TQFP-48 package. Consider the internal reference capabilities if external reference components are to be minimized, and verify that the input clock jitter requirements align with the device's aperture jitter specifications for the target frequency.

Analog To Digital Converters (ADC) Part Context

The ADS5221PFBT belongs to the ADS5220/ADS5221 family of high-speed, low-power CMOS analog-to-digital converters. This family is designed for applications requiring excellent dynamic performance and low power dissipation. The ADS5221 variant specifically offers a higher sampling rate of 65MSPS compared to the 40MSPS ADS5220, while maintaining similar pinouts and architectural features.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5220PFBT is a compatible alternative within the same family, offering identical functionality but with a reduced maximum sampling rate of 40MSPS. Verify that the lower sampling rate meets the system requirements before substituting.
