ADS5220PFBT

Analog To Digital Converters (ADC) Overview

The ADS5220PFBT is a 12-bit, 40MSPS pipeline analog-to-digital converter in a TQFP-48 package. It operates from a single +3.3V supply with 195mW power dissipation. Key electrical parameters include a typical SNR of 70dBFS and SFDR of 88dBFS at 2.4MHz input. The device features an internal reference or external reference option, programmable input range (1V to 2V differential), and low DNL of 0.3LSB. It supports single-ended or fully differential analog inputs and includes digital error correction logic.

• High dynamic performance: 70dB SNR and 88dB SFDR
• Low power consumption: 195mW at 3.3V supply
• Internal or external reference selection via RSEL pin

Analog To Digital Converters (ADC) Applications

• Wireless local loop systems
• Medical imaging equipment
• Portable instrumentation
• Communications infrastructure

Analog To Digital Converters (ADC) Procurement Notes

Verify the PFB suffix indicates the TQFP-48 package with -40°C to +85°C operating range. Confirm the 'T' suffix denotes tape and reel packaging quantity of 250 units. Ensure compatibility with single +3.3V supply requirements and check for specific revision levels if critical for legacy designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit ADC with moderate speed (40MSPS) and high linearity is required. Consider the internal reference for simplified design or external reference for multi-channel matching. Ensure the application can provide the necessary common-mode voltage bias (+1.25V single-ended, +1.5V differential) and low-jitter clock signal.

Analog To Digital Converters (ADC) Part Context

The ADS5220 is part of Texas Instruments' pipeline ADC family designed for general-purpose high-performance data conversion. The PFBT variant specifically refers to the plastic TQFP-48 package version supplied in tape and reel format, distinguishing it from the QFN-48 (RGZ) package options available in the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should consult Texas Instruments for current cross-reference recommendations or verify pinout and parameter compatibility before substituting with other 12-bit pipeline ADCs.
