LTC2291CUP#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2291CUP#TRPBF is a dual-channel, 12-bit analog-to-digital converter (ADC) from Analog Devices. It operates at a sampling rate of 25Msps with a single 3V supply (2.7V to 3.4V). The device features low power consumption of 150mW and high dynamic performance, including 71.4dB SNR and 90dB SFDR. It utilizes a pipeline architecture with an internal reference and supports differential or single-ended inputs within a ±0.5V to ±1V range. Packaged in a 64-lead QFN, it includes shutdown modes and a clock duty cycle stabilizer.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the 'C' grade corresponds to the commercial temperature range of 0°C to 70°C. Ensure the source document explicitly lists this part number as available from authorized distributors before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2291 over the LTC2293 or LTC2292 if a lower sampling rate of 25Msps is sufficient for the application, as it offers reduced power dissipation. Consider the LTC2298 if 14-bit resolution is required instead of 12-bit. Verify that the system clock duty cycle requirements align with the internal stabilizer capabilities when MODE pin is configured.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC229x family of low-power, dual-channel ADCs. It shares pin compatibility with the LTC2293 (65Msps) and LTC2292 (40Msps), allowing for design flexibility across different speed grades. The family is designed for demanding imaging and communications applications where AC performance and power efficiency are critical.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the LTC2293CUP#TRPBF (65Msps) and LTC2292CUP#TRPBF (40Msps). For higher resolution needs, the LTC2298CUP#TRPBF (14-bit, 65Msps) or LTC2297CUP#TRPBF (14-bit, 40Msps) are compatible options within the same package.
