LTC2263IUJ-14#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2263IUJ-14#TRPBF is a dual-channel, simultaneous sampling 14-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 25Msps. It features serial LVDS outputs and supports selectable input ranges from 1VP-P to 2VP-P. The device operates on a single 1.8V supply with total power dissipation of 94mW in standard mode. Key performance metrics include a signal-to-noise ratio (SNR) of 72.3dB at 5MHz input and a spurious-free dynamic range (SFDR) of 90dB. It utilizes an internal clock duty cycle stabilizer and includes shutdown and nap modes for power management.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging rather than tube packaging when sourcing components. Confirm the 'I' grade designation corresponds to the -40°C to +85°C industrial temperature range. Ensure the specific speed grade matches the 25Msps requirement, as other variants in the family operate at higher frequencies.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring low power consumption alongside moderate high-speed digitization. The 25Msps speed grade is suitable for undersampling IF frequencies where ultralow jitter of 0.15ps RMS is critical. Consider the 40-pin QFN package dimensions for PCB layout constraints and ensure compatibility with the serial LVDS interface requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2263-14/LTC2264-14/LTC2265-14 family of low-power dual ADCs. The LTC2263 variant specifically defines the 25Msps speed grade within this pin-compatible series. Other family members offer higher sampling rates such as 40Msps or 65Msps while maintaining similar architectural features and package options.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2264IUJ-14#TRPBF offers 40Msps performance. LTC2265IUJ-14#TRPBF provides 65Msps capability. Both share the same pinout and package but differ in maximum sampling frequency specifications.
