LTC2267IUJ-14#PBF

Analog To Digital Converters (ADC) Overview

The LTC2267IUJ-14#PBF is a dual-channel, simultaneous sampling 14-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 105 Msps. It features an ultralow jitter of 0.15 ps RMS and a full power bandwidth of 800 MHz. The device delivers a typical Signal-to-Noise Ratio (SNR) of 73.1 dB and a Spurious Free Dynamic Range (SFDR) of 88 dB. Power dissipation is 243 mW with a single 1.8 V supply. Digital outputs are serialized LVDS, configurable for 1 or 2 bits per channel. Integral nonlinearity is ±1 LSB, and differential nonlinearity is ±0.3 LSB.

Analog To Digital Converters (ADC) Applications

• Communications systems
• Cellular base stations
• Software defined radios
• Portable medical imaging
• Multichannel data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix '14' corresponds to the 105 Msps performance tier. Confirm the 'I' designation indicates the industrial temperature range of –40°C to 85°C. Ensure the '#PBF' suffix matches the required lead-free and RoHS compliance specifications for the target assembly process.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel simultaneous sampling is required at 105 Msps. Compare against the LTC2268-14 if 125 Msps is needed, or the LTC2266-14 if 80 Msps suffices. Verify that the serial LVDS output interface aligns with the downstream FPGA or processor capabilities. Check power budget constraints against the 243 mW total dissipation.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC226x-14 family of low-power dual ADCs. It shares the same 40-lead QFN package and pinout with the LTC2268-14 and LTC2266-14. The primary distinction is the sampling frequency specification, which defines the performance envelope relative to the other members in the series.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2268IUJ-14#PBF offers higher speed (125 Msps). LTC2266IUJ-14#PBF offers lower speed (80 Msps). Both are pin-compatible alternatives within the same package.
