LTC2263CUJ-12#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2263CUJ-12#TRPBF is a dual-channel, simultaneous sampling 12-bit analog-to-digital converter (ADC) from Analog Devices Inc. Operating at a maximum sampling rate of 25Msps, it features serial LVDS outputs and requires a single 1.8V supply. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 70.5dB, a Spurious Free Dynamic Range (SFDR) of 90dB, and ±0.3LSB Integral Nonlinearity (INL). The device dissipates 94mW of power in standard operation and utilizes a 40-lead 6mm × 6mm QFN package with an exposed ground pad.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF confirms tape and reel packaging and lead-free finish. Confirm the 'C' grade indicates a commercial operating temperature range of 0°C to 70°C. Ensure the source documentation matches the specific part number to avoid confusion with industrial grade variants.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 25Msps sampling speed with low power consumption. Verify that the 1.8V supply voltage aligns with system requirements. Consider the 40-pin QFN package dimensions for PCB layout constraints and ensure thermal management supports the 94mW power dissipation.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2263-12 family, which includes simultaneous sampling dual ADCs. It shares pin compatibility with the higher-speed LTC2264-12 (40Msps) and LTC2265-12 (65Msps) variants, as well as 14-bit versions within the same series.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the LTC2264IUJ-12#TRPBF and LTC2265IUJ-12#TRPBF for higher speed requirements. For identical performance but industrial temperature range, consider the LTC2263IUJ-12#TRPBF.
