LTC2205CUK-14

Analog To Digital Converters (ADC) Overview

The LTC2205CUK-14 is a 14-bit, 65Msps pipeline analog-to-digital converter (ADC) from Analog Devices. It features an internal programmable gain amplifier (PGA) allowing selectable input ranges of 2.25Vp-p or 1.5Vp-p. The device operates on a single 3.3V supply with a typical power dissipation of 600mW. Key performance metrics include a signal-to-noise ratio (SNR) of 78.3dB and a spurious-free dynamic range (SFDR) of 98dB at a 2.25Vp-p input range. It utilizes a 48-lead 7mm x 7mm QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix for the commercial temperature grade (C) when ordering. Confirm lead-free finish availability as indicated by the #PBF designation in official documentation. Check current distribution status as supply conditions may vary.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring high linearity and low jitter at 65Msps. Ensure the system supports differential encode inputs and provides appropriate clock duty cycle stabilization if required. Verify that the 48-QFN package footprint matches the PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2205 family of high-speed ADCs. It shares pin compatibility with other variants in the series, including the 16-bit LTC2205 and higher-speed models like the LTC2206 and LTC2207. The -14 suffix specifically denotes the 14-bit resolution variant within this product line.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the LTC2205 (16-bit), LTC2206-14 (80Msps), and LTC2207-14 (105Msps). Selection depends on whether increased resolution or sampling speed is required while maintaining the same interface and package.
