LTC2256IUJ-14#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2256IUJ-14#TRPBF is a 14-bit, 25Msps ultralow power analog-to-digital converter (ADC) from Analog Devices. It operates on a single 1.8V supply and features a pipeline architecture with differential or single-ended inputs. Key electrical parameters include a typical Signal-to-Noise Ratio (SNR) of 71.8dB at 25Msps, an 800MHz full-power bandwidth sample-and-hold, and ±1LSB integral nonlinearity. Power dissipation is typically 35mW. The device supports CMOS, DDR CMOS, or DDR LVDS digital outputs and includes an internal reference, shutdown modes, and an SPI configuration port.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the 'I' grade designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the source document explicitly lists this part number as available; distributor listings may vary by region.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2256 variant for applications requiring 25Msps throughput. Choose the IUJ package for the 40-lead QFN form factor. Consider the LTC2257 or LTC2258 if higher sampling rates of 40Msps or 65Msps are required, noting the corresponding increase in power dissipation.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2256-14/LTC2257-14/LTC2258-14 family of ultralow power 1.8V ADCs. The specific model LTC2256 represents the 25Msps speed grade within this series, sharing pin compatibility and architectural features with the faster variants while optimizing for lower power usage.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the LTC2257IUJ-14#TRPBF (40Msps) and LTC2258IUJ-14#TRPBF (65Msps). These offer higher sampling speeds but consume more power. Verify that the system clock and power budget accommodate the performance differences.
