ADS5102CPFBR

Analog To Digital Converters (ADC) Overview

The ADS5102CPFBR 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 and digital 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 configurations. Digital outputs are compatible with both 1.8 V and 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 under the same conditions.

Analog To Digital Converters (ADC) Feature Summary

• 65 MSPS Sampling Rate: High-speed conversion using a 10-stage switched-capacitor pipeline architecture.
• Differential Input Architecture: Fully differential analog inputs provide excellent common-mode noise rejection.
• Flexible Power Supply: Operates on a single 1.8 V supply with a standby mode reducing power consumption to 336 µW.
• Logic Compatibility: Digital outputs support both 1.8 V and 3.3 V CMOS logic levels controlled by the DRVDD 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 package type matches the PFB (48-TQFP) specification when sourcing. Confirm the temperature grade corresponds to the 'C' suffix (0°C to 70°C). Ensure the ordering suffix 'B' indicates tape and reel packaging if required for automated assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS5102CPFBR over the ADS5103 variant when a sampling rate of 65 MSPS is required rather than 40 MSPS. Consider the internal reference limitations; use an external reference if stricter DC accuracy or lower temperature drift is needed. Ensure the driving amplifier has sufficient bandwidth and low output impedance to handle the dynamic input capacitance at 65 MSPS.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS5102/ADS5103 family of low-power CMOS ADCs. The ADS5102 variant specifically targets higher speed applications up to 65 MSPS compared to the 40 MSPS ADS5103. Both share the same 10-bit resolution and pipeline architecture but differ in maximum clock frequency and associated power dissipation characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate other Texas Instruments high-speed ADCs based on specific interface and performance requirements.
