LTC2241CUP-12#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2241CUP-12#TRPBF is a single-channel, 12-bit, 210Msps pipelined analog-to-digital converter manufactured by Analog Devices Inc. It operates on a single 2.5V supply with typical power dissipation of 585mW in CMOS mode. The device features ultralow jitter of 95fs RMS and supports selectable input ranges of ±0.5V or ±1V via the SENSE pin. Digital outputs are configurable as differential LVDS or single-ended CMOS with full-rate or demultiplexed formats. Key performance metrics include 65.5dB SNR and 78dB SFDR at 10MHz input frequency.

Analog To Digital Converters (ADC) Feature Summary

• Configurable digital outputs: LVDS, Full-Rate CMOS, or Demuxed CMOS
• Ultralow aperture jitter of 95fs RMS for high-frequency undersampling

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 #TRPBF indicates lead-free finish and tape-and-reel packaging. Confirm the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure compatibility with the 64-lead QFN package dimensions and exposed pad soldering requirements specified in the datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-speed digitization with low power constraints. Choose LVDS output mode for noise immunity over long traces; use CMOS mode for lower power and direct interface with standard logic. Verify that the input signal amplitude fits within the ±0.5V or ±1V selectable range defined by the SENSE pin configuration.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2241-12 family, which includes variants with different sampling rates such as the LTC2242-12 (250Msps) and LTC2240-12 (170Msps). These parts share pin compatibility and architectural similarities, allowing for design flexibility across different bandwidth requirements within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the LTC2242-12 for higher speed or LTC2240-12 for lower power needs. For broader temperature ranges, consider the LTC2241IUP-12 variant (-40°C to 85°C). Ensure replacement parts match the specific output format and supply voltage requirements of the existing design.
