LTC2265IUJ-12#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2265IUJ-12#TRPBF is a dual-channel, simultaneous sampling 12-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 65Msps. It features an ultralow jitter of 0.15ps RMS and delivers a signal-to-noise ratio (SNR) of 71dB with a spurious-free dynamic range (SFDR) of 90dB. The device operates on a single 1.8V supply, consuming 167mW total power in standard modes. It utilizes serial LVDS outputs for data transmission and includes an internal clock duty cycle stabilizer. The component is housed in a 40-lead 6mm x 6mm QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging suitable for automated surface-mount assembly. Confirm the 'I' grade designation corresponds to the –40°C to 85°C industrial temperature range. Ensure the source documentation matches the specific lot marking and lead finish specifications provided by Analog Devices.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC2264-12 or LTC2263-12 when a 65Msps sampling rate is required. Verify that the 1.8V single-supply operation aligns with system power constraints. Consider the 40-pin QFN footprint for PCB layout compatibility. Evaluate the 167mW power dissipation against thermal management capabilities if operating at full speed.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC226x-12 family of low-power dual ADCs from Analog Devices. It shares pinout compatibility with the 14-bit versions and the lower-speed LTC2264-12 and LTC2263-12 variants. The series is designed for high-frequency signal digitization where power efficiency and dynamic range are critical.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2265IUJ-12#PBF offers identical electrical specifications but uses tube packaging instead of tape and reel.
