ADS5204IPFBR

Analog To Digital Converters (ADC) Overview

The ADS5204IPFBR is a dual-channel, 10-bit Analog-to-Digital Converter (ADC) from Texas Instruments. It operates at a maximum sampling rate of 40MSPS per channel with a 300MHz analog input bandwidth. The device features a single 3.3V supply and includes onboard Programmable Gain Amplifiers (PGAs) adjustable from 0dB to 18dB. Key electrical specifications include a Signal-to-Noise Ratio (SNR) of 60.5dB at an input frequency of 10.5MHz and a Spurious-Free Dynamic Range (SFDR) of 73dB under the same conditions. Power dissipation is typically 275mW. The component utilizes a parallel digital interface and is housed in a TQFP-48 package.

Analog To Digital Converters (ADC) Feature Summary

• Dual simultaneous sample-and-hold inputs with independent PGA control (0dB to 18dB gain range).
• Supports both differential and single-ended analog input configurations.
• Features internal or external voltage reference options with adjustable input ranges.
• Includes a separate serial control interface for register configuration.

Analog To Digital Converters (ADC) Applications

• Digital communications baseband sampling.
• Portable instrumentation systems.
• Video processing applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'IPFBR' against current manufacturer documentation to confirm tape and reel packaging and temperature grade. Confirm availability status as legacy components may have limited stock or end-of-life designations. Ensure compliance with RoHS directives by checking the latest datasheet revision for material declarations before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel high-speed conversion is required within a low-power constraint. The integrated PGA allows signal conditioning without external amplifiers. Verify that the system clock supports up to 80MHz for full 40MSPS operation per channel. Ensure the host processor can handle the parallel data bus timing and pipeline latency requirements specified in the timing diagrams.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS520x family of high-speed ADCs. It shares architectural similarities with the ADS5203 but offers distinct pinout and feature configurations suitable for specific dual-channel applications. The IPFBR designation indicates a TQFP-48 package variant intended for surface-mount assembly on printed circuit boards.

Analog To Digital Converters (ADC) Replacement Considerations

Consult official Texas Instruments cross-reference tools for verified substitutes. Generic replacements may not match the specific PGA gain steps or timing characteristics. Validate pin compatibility and power supply requirements before integrating alternative components into existing designs.
