ADS5102IPFBR

Analog To Digital Converters (ADC) Overview

The ADS5102IPFBR is a low-power, 10-bit analog-to-digital converter (ADC) operating at a sampling rate of 65 MSPS. It utilizes a switched-capacitor pipeline architecture and functions from a single 1.8-V supply. The device features differential analog inputs and an internal voltage reference that can be bypassed for external configurations. Digital outputs are compatible with 1.8 V or 3.3 V logic levels via the DRVDD pin. Key performance metrics include a signal-to-noise ratio of 57 dB at 20 MHz input frequency and a spurious-free dynamic range of 71 dB at 20 MHz. Power dissipation is typically 188 mW.

Analog To Digital Converters (ADC) Feature Summary

• 65 MSPS Sampling Rate: High-speed conversion using a 10-stage switched-capacitor pipeline architecture.
• Low Power Consumption: Operates on a single 1.8-V supply with typical power dissipation of 188 mW and a standby mode reducing consumption to 336 µW.
• Flexible Logic Interface: Digital outputs support both 1.8 V and 3.3 V CMOS logic levels controlled by the DRVDD supply.
• Integrated Reference: Includes an internal voltage reference; supports external reference configuration via PDREF pin.

Analog To Digital Converters (ADC) Applications

• Ultrasound imaging systems
• Digital cameras
• Baseband digitization in communications
• General-purpose imaging applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BR' against the manufacturer's ordering information to confirm tape-and-reel packaging. Confirm the 'I' designation indicates the industrial temperature range of -40°C to +85°C. Ensure compatibility with the 48-TQFP package dimensions for PCB layout. Check current production status as this component may be subject to obsolescence notices.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS5102IPFBR when a 65 MSPS sampling rate is required for high-frequency baseband or undersampling applications. Choose this part over the ADS5103 if higher speed is needed, noting the increased power dissipation. Ensure the system design accommodates the 1.8 V analog supply and allows for 3.3 V digital interfacing if DRVDD is set accordingly. Verify that the load capacitance on digital outputs remains below 15 pF to maintain specified performance.

Analog To Digital Converters (ADC) Part Context

The ADS5102IPFBR belongs to the ADS510x family of low-power, 10-bit ADCs manufactured by Texas Instruments. This family includes the ADS5102 (65 MSPS) and ADS5103 (40 MSPS). Both variants share the same 48-TQFP package and architectural features, differing primarily in maximum sampling speed and associated power consumption profiles.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5103IPFBR serves as a lower-speed alternative within the same package and family. No other direct cross-model replacements are documented in the provided datasheet.
