LTC2233CUK#PBF

Analog To Digital Converters (ADC) Overview

The LTC2233CUK#PBF is a 10-bit, 80Msps analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It utilizes a CMOS pipelined architecture and operates on a single 3.3V supply with a typical power dissipation of 366mW. The device features an ultralow jitter of 0.15ps RMS, enabling effective undersampling of intermediate frequencies. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 61.3dB at 30MHz input and a Spurious Free Dynamic Range (SFDR) of 75dB up to 200MHz input frequency. It supports selectable input ranges of ±0.5V or ±1V via the SENSE pin.

Analog To Digital Converters (ADC) Feature Summary

• 80Msps sampling rate with 10-bit resolution and no missing codes
• Ultralow aperture delay jitter of 0.15ps RMS for high-frequency signal integrity
• Selectable analog input ranges: ±0.5V or ±1V controlled by the SENSE pin
• Integrated clock duty cycle stabilizer and optional shutdown/nap modes

Analog To Digital Converters (ADC) Applications

• Wireless and wired broadband communication systems
• Cable head-end systems
• Power amplifier linearization
• Communications test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free status and #TRPBF indicates tape and reel packaging. Confirm the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the specific package variant matches the 48-lead QFN footprint requirements for the target PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2233CUK#PBF when an 80Msps sampling speed is sufficient for the application, as opposed to the 105Msps LTC2232. Consider the internal reference configuration via the SENSE pin to determine if ±0.5V or ±1V input range is required. Evaluate the need for the clock duty cycle stabilizer based on the input clock source characteristics.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2232/LTC2233 family of high-speed ADCs. It is pin-compatible with the 105Msps LTC2232 and the 135Msps LTC2234. The family shares a common 48-pin 7mm x 7mm QFN package and functional interface, allowing for design flexibility across different bandwidth requirements.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2232CUK#PBF serves as a higher-speed alternative within the same package. For 12-bit resolution requirements, consider the LTC2223CUK#PBF. Verify that any substitute maintains the 48-QFN footprint and compatible digital output logic levels.
