LTC2258CUJ-14#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2258CUJ-14#TRPBF is a 14-bit, 65Msps ultralow power analog-to-digital converter (ADC) from Analog Devices Inc. It operates on a single 1.8V supply and delivers 74dB SNR and 88dB SFDR with an ultralow jitter of 0.17psRMS. The device features selectable input ranges from 1VP-P to 2VP-P and an 800MHz full-power bandwidth sample-and-hold circuit. Digital outputs support full-rate CMOS, double data rate CMOS, or double data rate LVDS configurations. It includes an optional clock duty cycle stabilizer, shutdown/nap modes, and a serial SPI port for configuration.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging rather than tube packaging. Confirm the 'C' grade designation corresponds to the 0°C to 70°C operating temperature range. Ensure the order matches the specific 65Msps variant within the LTC2258-14 family.

Analog To Digital Converters (ADC) Selection Notes

Select this part for high-frequency signal digitization requiring low power and wide dynamic range. Compare against LTC2257-14 (40Msps) or LTC2256-14 (25Msps) if lower sampling rates suffice. Verify compatibility with CMOS or LVDS interface requirements and ensure the 1.8V supply rail aligns with system design constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2258-14 series, which includes pin-compatible 14-bit and 12-bit versions. It shares the same 40-lead QFN package and core architecture with the LTC2257-14 and LTC2256-14, differing primarily in maximum sampling speed and associated power dissipation characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the LTC2257CUJ-14#TRPBF (40Msps) and LTC2256CUJ-14#TRPBF (25Msps). These offer lower power consumption but reduced sampling speeds. No other direct functional substitutes are documented.
