ADS5102CPFBRG4

Analog To Digital Converters (ADC) Overview

The ADS5102CPFBRG4 is a 10-bit, 65 MSPS analog-to-digital converter (ADC) from Texas Instruments. It operates on a single 1.8-V supply and features a differential input architecture with an internal voltage reference. The device utilizes a switched-capacitor pipeline design to achieve high conversion speeds while maintaining low power consumption of approximately 188 mW. 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 signal-to-noise ratio (SNR) of 57 dB at 20 MHz.

Analog To Digital Converters (ADC) Applications

• Ultrasound imaging systems
• Digital cameras
• Baseband digitization
• Communications equipment
• General-purpose imaging applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type PFB (48-TQFP) and tape-and-reel packaging indicated by the 'BR' suffix. Confirm the temperature grade corresponds to the standard commercial range (0°C to 70°C) as specified for the CPFBR variant. Ensure the G4 suffix indicates lead-free and RoHS compliance status per manufacturer standards.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution and 65 MSPS speed are required within a low-power constraint. The differential input architecture is suitable for applications demanding high common-mode noise rejection. Consider the internal reference for simplified designs or use the PDREF pin to accommodate external references for tighter DC accuracy requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS5102/ADS5103 family of low-power CMOS ADCs. The ADS5102 variant specifically supports up to 65 MSPS, whereas the ADS5103 is limited to 40 MSPS. Both share the same architectural features, including the 10-stage pipeline structure and single 1.8-V supply operation.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5103 serves as a lower-speed alternative within the same family. For direct functional replacement, verify that the system clock does not exceed 40 MSPS if substituting with the ADS5103. No other cross-model substitutes are documented in the provided datasheet.
