ADS5102IPFB

Analog To Digital Converters (ADC) Overview

The ADS5102IPFB is a low-power, 10-bit analog-to-digital converter (ADC) from Texas Instruments operating at a maximum sampling rate of 65 MSPS. It utilizes a single 1.8-V supply and features a differential switched-capacitor pipeline architecture with an internal voltage reference. The device provides a 10-bit parallel output bus with 3-state buffers 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 and a spurious-free dynamic range of 71 dB at 20 MHz. Total power dissipation is 160 mW to 188 mW under standard conditions.

Analog To Digital Converters (ADC) Feature Summary

• Low standby power consumption of 336 µW in power-down mode

Analog To Digital Converters (ADC) Applications

• Ultrasound imaging systems
• Digital cameras
• Baseband digitization
• Communications equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the required 48-TQFP (PFB) configuration. Confirm that the temperature grade corresponds to the industrial range (-40°C to +85°C). Ensure the ordering suffix aligns with the desired packaging format, such as tray or tape and reel, before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 65 MSPS sampling rate is required for 10-bit conversion. Consider the ADS5103 if a lower 40 MSPS rate suffices, as it offers reduced power consumption. Ensure the system design accommodates the 1.8-V analog supply and supports either 1.8-V or 3.3-V digital driver supplies based on the DRVDD connection.

Analog To Digital Converters (ADC) Part Context

The ADS5102IPFB belongs to the ADS5102/ADS5103 family of low-power CMOS ADCs. This series is designed for applications requiring high speed and low power consumption. The IPFB variant specifically denotes the industrial temperature range and TQFP packaging, distinguishing it from commercial variants or other package options within the same functional family.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5103 serves as a slower alternative within the same family, offering 40 MSPS operation. Verify compatibility regarding sampling rate requirements and power budget constraints when considering substitution.
