LTC2165IUK#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2165IUK#TRPBF is a 16-bit, 125Msps low-power analog-to-digital converter (ADC) from Analog Devices. It features an ultralow jitter of 0.07ps RMS and supports selectable input ranges from 1VP-P to 2VP-P. The device operates on a single 1.8V supply with power dissipation of 194mW. Digital outputs are available in full-rate CMOS, double data rate CMOS, or double data rate LVDS formats. Key performance metrics include a typical SNR of 76.8dB and SFDR of 90dB at 70MHz input frequency.

Analog To Digital Converters (ADC) Procurement Notes

Verify the I suffix indicates the industrial temperature range (-40°C to 85°C). Confirm the UK package is a 48-lead 7mm x 7mm plastic QFN. Ensure the #TRPBF designation matches the required tape and reel packaging format for automated assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 125Msps throughput with 16-bit precision. Compare against LTC2164 (105Msps) and LTC2163 (80Msps) if lower speed or power consumption is acceptable. Verify that the chosen digital output mode (CMOS vs LVDS) aligns with the downstream receiver interface requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC216x family of 16-bit low-power ADCs. The 'I' grade specifies operation from -40°C to 85°C, while the 'C' grade covers 0°C to 70°C. The 'UK' suffix denotes the specific 48-lead QFN package geometry used for surface mount installation.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2164IUK#TRPBF offers identical specifications except for a reduced maximum sampling rate of 105Msps. LTC2163IUK#TRPBF provides further power reduction with an 80Msps limit. These variants share the same pinout and software configuration compatibility.
