LTC2268CUJ-14#PBF

Analog To Digital Converters (ADC) Overview

The LTC2268CUJ-14#PBF is a dual-channel, simultaneous sampling 14-bit analog-to-digital converter (ADC) operating at 125Msps. It features an ultralow jitter of 0.15ps RMS and a full power bandwidth of 800MHz. The device delivers a typical Signal-to-Noise Ratio (SNR) of 73.1dB and a Spurious Free Dynamic Range (SFDR) of 88dB. Power consumption is 299mW total with a single 1.8V supply. Digital outputs utilize serial LVDS with selectable 1 or 2 bits per channel. Integral nonlinearity is ±1LSB typical, and differential nonlinearity is ±0.3LSB typical.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component grade suffix 'C' indicates a commercial temperature range of 0°C to 70°C. Confirm the '#PBF' designation corresponds to lead-free packaging in a 40-lead QFN format. Ensure compatibility with the required 1.8V analog and digital supply voltages for the specific application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring high dynamic range and low power consumption. Compare against the LTC2267-14 (105Msps) and LTC2266-14 (80Msps) if lower sampling rates suffice. Verify that the serial LVDS interface meets the receiver requirements. Check pin compatibility with existing 12-bit versions if migrating designs.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2268-14/LTC2267-14/LTC2266-14 family of low-power dual ADCs. The 'CUJ' identifier specifies the commercial temperature grade and the 40-lead QFN package. The '#PBF' suffix denotes a lead-free finish. It shares the same pinout as the 12-bit variants within the series.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2267CUJ-14#PBF and LTC2266CUJ-14#PBF are pin-compatible alternatives offering 105Msps and 80Msps speeds respectively. Other 14-bit or 12-bit parts in the LTC226x series may serve as substitutes if speed requirements allow.
