ADS5203IPFBR

Analog To Digital Converters (ADC) Overview

The ADS5203IPFBR is a dual-channel, 10-bit analog-to-digital converter (ADC) operating at sampling rates up to 40MSPS. It utilizes a dual-pipeline architecture and operates on a single 3.3V supply. The device features differential or single-ended analog inputs with a 300MHz analog input bandwidth. Digital I/Os are 3.3V TTL/CMOS compatible. Key electrical parameters include a typical 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 rated at 240mW to 290mW depending on reference configuration.

Analog To Digital Converters (ADC) Feature Summary

• Dual simultaneous sample-and-hold inputs with 10-bit resolution at 40MSPS per channel
• Supports both differential and single-ended analog input configurations
• Integrated internal voltage references or provision for external adjustable reference inputs
• Low power consumption of 240mW with standby mode capability

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distribution channels as this part is marked Not Recommended For New Designs. Confirm package integrity upon receipt, specifically checking for TQFP-48 pin alignment and absence of physical damage. Ensure handling precautions are observed due to ESD sensitivity. Review current availability status as manufacturing may be discontinued.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel 10-bit conversion at 40MSPS is required within a 3.3V system. Ensure the application supports parallel digital output interfaces. Verify that the analog input signal range aligns with the 1Vp-p differential input specification defined by the reference voltage difference. Consider thermal management for power dissipation levels up to 290mW in enclosed environments.

Analog To Digital Converters (ADC) Part Context

The ADS5203 belongs to the ADS5203 series of high-speed ADCs from Texas Instruments. It is housed in a TQFP-48 package. The 'I' suffix indicates an industrial temperature range of -40°C to +85°C. The 'BR' suffix denotes the Tape and Reel transport media containing 1000 units. This specific variant replaces older tray-packaged versions like the ADS5203IPFB.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate newer Texas Instruments ADC families for updated designs, as this component is marked Not Recommended For New Designs.
