LTC2263CUJ-14

Analog To Digital Converters (ADC) Overview

The LTC2263CUJ-14 is a dual-channel, simultaneous sampling analog-to-digital converter with 12-bit resolution and a maximum sampling rate of 25Msps. It operates on a single 1.8V supply, consuming 94mW of total power. The device features serial LVDS outputs configurable for 1 or 2 bits per channel, selectable input ranges from 1VP-P to 2VP-P, and an internal clock duty cycle stabilizer. Static performance includes ±0.3LSB typical integral nonlinearity (INL) and ±0.1LSB differential nonlinearity (DNL). Dynamic specifications provide 71dB SNR and 90dB SFDR at 5MHz input.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'C' suffix indicates a commercial temperature range of 0°C to 70°C. Confirm the '#PBF' designation corresponds to lead-free tube packaging. Ensure the specific speed grade matches the required 25Msps sampling frequency for the target application design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization is required at moderate speeds. Compare against the LTC2264-12 (40Msps) and LTC2265-12 (65Msps) if higher throughput is needed. Verify that the 1.8V supply voltage aligns with system power rails and that LVDS output drivers match the receiver interface requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2263-12 family of low-power dual ADCs. It shares pin compatibility with the 14-bit versions in the same series. The device utilizes a pipeline architecture optimized for high dynamic range signal digitization in bandwidth-constrained environments.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same package include the LTC2264-12 and LTC2265-12 for higher speed requirements. For lower speed needs, verify availability of legacy parts. Ensure replacement parts maintain the 1.8V supply and LVDS output interface compatibility.
