LTC2265IUJ-14#PBF

Analog To Digital Converters (ADC) Overview

The LTC2265IUJ-14#PBF is a dual-channel, simultaneous sampling 14-bit analog-to-digital converter (ADC) from Analog Devices. Operating at a maximum sampling rate of 65Msps with a single 1.8V supply, it delivers a typical Signal-to-Noise Ratio (SNR) of 73.7dB and a Spurious Free Dynamic Range (SFDR) of 90dB. The device features an ultralow jitter of 0.15ps RMS, ±1LSB Integral Nonlinearity (INL), and ±0.3LSB Differential Nonlinearity (DNL). It utilizes serial LVDS outputs for data transmission and includes internal reference and clock duty cycle stabilization.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific temperature grade suffix 'I' indicates operation within –40°C to 85°C. Confirm the '#PBF' designation corresponds to lead-free packaging in tube format. Ensure compatibility with the 40-pin QFN footprint during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this model when dual-channel simultaneous sampling is required at 14-bit resolution. Compare against LTC2264-14 (40Msps) or LTC2263-14 (25Msps) if lower power or reduced bandwidth suffices. Verify that the 1.8V single-supply requirement aligns with system power constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2265-14/LTC2264-14/LTC2263-14 family of low-power dual ADCs. It shares pin compatibility with 12-bit versions in the same series. The 'I' suffix denotes industrial temperature range, while 'UJ' specifies the 40-lead plastic QFN package.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the LTC2264IUJ-14#PBF (40Msps) and LTC2263IUJ-14#PBF (25Msps). These variants offer lower power consumption but operate at reduced sampling frequencies.
