ADS5102CPFBG4

Analog To Digital Converters (ADC) Overview

The ADS5102CPFBG4 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 switched-capacitor pipeline architecture and functions on a single 1.8-V analog supply. The device features differential analog inputs for superior common-mode noise rejection and includes an internal voltage reference that can be bypassed for external references. Digital outputs are compatible with both 1.8 V and 3.3 V logic levels via the DRVDD pin. Key performance metrics include a spurious-free dynamic range (SFDR) of 71 dB at 20 MHz and a power dissipation of 160 mW under standard conditions.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the PFB (48-TQFP) specification. Confirm the suffix G4 indicates lead-free and RoHS compliance as per Texas Instruments standards. Ensure the ordering code corresponds to the Tape and Reel variant if bulk handling is required, distinct from the Tray packaging.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-speed 10-bit conversion with low power constraints. The ADS5102 supports up to 65 MSPS; ensure clock jitter remains below 3.98 ps rms for optimal SNR at Nyquist frequencies. Verify that the DRVDD supply aligns with the target digital logic voltage (1.8 V or 3.3 V). Consider the 5.5-clock pipeline latency when designing timing-critical interfaces.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS5102/ADS5103 family of low-power CMOS ADCs. The ADS5103 variant offers a lower sampling rate of 40 MSPS with reduced power consumption (105 mW). Both devices share the same architectural features, including the 10-stage pipeline structure and differential input capabilities, catering to different speed and power requirements within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5103 serves as a lower-speed alternative within the same family. No other direct cross-model replacements are documented in the provided datasheet.
