LTC2165IUK#PBF

Analog To Digital Converters (ADC) Overview

The LTC2165IUK#PBF is a 16-bit, 125Msps low-power analog-to-digital converter (ADC) from Analog Devices. It features a single 1.8V supply and delivers 76.8dB SNR and 90dB SFDR with ultralow jitter of 0.07ps RMS. The device supports selectable input ranges from 1VP-P to 2VP-P and offers full-rate CMOS, double data rate CMOS, or double data rate LVDS digital outputs. It includes an internal reference, optional clock duty cycle stabilizer, and serial SPI configuration port. Packaged in a 48-lead 7mm × 7mm QFN, it operates within the industrial temperature range of –40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free finish and tube packaging when sourcing. Confirm the 'I' grade designation matches the required –40°C to 85°C operating temperature range for the application environment. Ensure the 48-pin QFN footprint aligns with the PCB layout specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this model for high-speed applications requiring 16-bit precision at 125Msps. Compare against LTC2164 (105Msps) or LTC2163 (80Msps) if lower sampling rates suffice for reduced power consumption. Consider the output interface requirements; LVDS modes may be necessary for long-distance signal integrity compared to CMOS outputs.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2165/LTC2164/LTC2163 family of 16-bit low-power ADCs. The 'I' suffix denotes the industrial temperature grade, while 'UK' specifies the 48-lead plastic QFN package. The '#PBF' suffix confirms RoHS compliance and lead-free manufacturing process.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2164IUK#PBF offers identical pinout and functionality but operates at a maximum sampling rate of 105Msps. LTC2163IUK#PBF provides further power reduction with an 80Msps limit. These variants are electrically compatible regarding interfaces and resolutions.
