ADS5203IPFB

Analog To Digital Converters (ADC) Overview

The ADS5203IPFBR is a dual 10-bit, 40MSPS Analog-to-Digital Converter (ADC) from Texas Instruments. It features simultaneous sampling on two channels with a 300MHz analog input bandwidth and 3.3V single-supply operation. The device delivers 60dB SNR at 10.5MHz input frequency and 73dB SFDR under the same conditions. Power consumption is 240mW during normal operation, reducing to 95µW in standby mode. It utilizes a dual-pipeline architecture and supports differential or single-ended analog inputs with TTL/CMOS-compatible digital I/O.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix for packaging requirements. The IPFB designation indicates a TQFP-48 package. Confirm temperature range specifications (-40°C to +85°C) match application needs. Check datasheet revision status as this component is marked 'Not Recommended For New Designs'. Ensure compatibility with existing board layouts regarding pin configuration and decoupling requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel simultaneous sampling at 40MSPS is required with 10-bit resolution. Consider the 3.3V supply constraint and TTL/CMOS logic levels for interface compatibility. Evaluate the internal reference capability versus external reference precision needs. Assess power budget constraints given the 240mW active power dissipation and available standby modes.
