LTC2266IUJ-14

Analog To Digital Converters (ADC) Overview

The LTC2266IUJ-14 is a dual-channel, simultaneous sampling analog-to-digital converter (ADC) with 14-bit resolution and an 80Msps sampling rate. It operates on a single 1.8V supply and dissipates 200mW of total power. The device features serial LVDS outputs supporting 1 or 2 bits per channel, selectable input ranges from 1VP-P to 2VP-P, and an 800MHz full-power bandwidth sample-and-hold. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 70.6dB and a Spurious Free Dynamic Range (SFDR) of 88dB. It includes shutdown and nap modes for power management and utilizes an internal SPI port for configuration.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix when ordering. The datasheet provided covers the LTC2266-12 variant; confirm that the 'I' suffix denotes the industrial temperature range (-40°C to 85°C) and that the '#PBF' indicates lead-free packaging through official Analog Devices documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring synchronized dual-channel digitization at moderate high speeds. Ensure the system supports serial LVDS interfaces. Verify that the 80Msps sampling rate meets the Nyquist requirements for the target signal frequencies and that the 14-bit resolution provides sufficient dynamic range for the application noise floor.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC226x family of low-power high-speed ADCs. It shares pin compatibility with the 12-bit versions (LTC2266-12) and other speed grades like the LTC2267-12 (105Msps) and LTC2268-12 (125Msps). The 'IUJ' designation specifies the industrial temperature range and the 40-lead QFN package.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the LTC2266CUJ-14#PBF for commercial temperature range and the LTC2267IUJ-14#PBF for higher 105Msps performance. Verify thermal and electrical specifications match before substitution.
