ADS5102CPFB

Analog To Digital Converters (ADC) Overview

The ADS5102CPFB 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 provides a 10-bit parallel output bus with 3-state outputs 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. Power consumption is 160 mW to 188 mW under standard operating conditions, with a standby mode reducing dissipation to 336 µW.

Analog To Digital Converters (ADC) Feature Summary

• Differential analog inputs providing superior common-mode noise rejection
• Internal voltage reference with option for external reference configuration
• Digital outputs compatible with 1.8 V or 3.3 V logic levels

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 package type matches the PFB (48-TQFP) specification. Confirm the temperature grade corresponds to the CP suffix (0°C to 70°C). Ensure the datasheet revision SLAS351B is referenced for accurate electrical characteristics and timing diagrams during design validation.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS5102CPFB for applications requiring up to 65 MSPS sampling speed. Choose the ADS5103 variant if a lower 40 MSPS rate is sufficient, as it offers reduced power consumption. Ensure the system clock jitter is below 3.98 ps rms to maintain optimal SNR at Nyquist frequencies.

Analog To Digital Converters (ADC) Part Context

The ADS5102CPFB belongs to the ADS5102/ADS5103 family of low-power CMOS ADCs. It shares architectural similarities with the ADS5103 but supports a higher maximum sampling rate of 65 MSPS compared to the 40 MSPS limit of the ADS5103. Both devices utilize a 10-stage pipeline structure for high-speed conversion.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS5103CPFB is a functional alternative within the same family, offering identical pinouts and features but limited to a 40 MSPS sampling rate.
