LTC2266IUJ-14#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2266IUJ-14#TRPBF is a dual-channel, simultaneous sampling 14-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 80Msps. It features an ultralow jitter of 0.15ps RMS and delivers a typical Signal-to-Noise Ratio (SNR) of 73.1dB with an 88dB Spurious Free Dynamic Range (SFDR). The device operates on a single 1.8V supply with total power dissipation of 203mW in 2-lane mode. Digital outputs utilize serial LVDS with selectable 1 or 2 bits per channel. Key DC specifications include ±1LSB Integral Nonlinearity (INL) and ±0.3LSB Differential Nonlinearity (DNL).

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel simultaneous sampling architecture with 14-bit resolution.
• 80Msps sampling rate with 0.15ps RMS jitter for high-frequency undersampling.
• Serial LVDS digital outputs supporting 1-lane or 2-lane modes.
• Internal reference with selectable input ranges via the SENSE pin.

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 that the #TRPBF suffix indicates tape and reel packaging, distinct from the tube-packaged #PBF variant. Confirm the 'I' grade designation corresponds to the –40°C to 85°C industrial temperature range. Ensure the specific speed grade matches the 80Msps requirement, as other variants in the family operate at higher frequencies.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel simultaneous sampling is required at 80Msps with low power consumption. The internal reference simplifies design if the SENSE pin configuration meets input range needs. Consider the 1-lane vs. 2-lane output mode based on available serial interface bandwidth and pin count constraints in the target system.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2266-14/LTC2267-14/LTC2268-14 family of low-power dual ADCs. The LTC2266-14 is the lowest speed variant at 80Msps, while the LTC2267-14 operates at 105Msps and the LTC2268-14 at 125Msps. All share identical pinouts and functional blocks, differing primarily in sampling speed and associated power dissipation.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2267IUJ-14#TRPBF and LTC2268IUJ-14#TRPBF are pin-compatible replacements offering higher sampling rates (105Msps and 125Msps respectively). Verify that the increased performance does not exceed power budget constraints and that the system timing accommodates the faster data rates.
