LTC2291IUP#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2291IUP#TRPBF is a dual 12-bit, 25Msps low-power analog-to-digital converter (ADC) from Analog Devices. It operates on a single 3V supply (2.7V to 3.4V) with a typical power dissipation of 150mW. The device features two independent ADC channels with flexible input ranges of 1VP-P to 2VP-P and a full power bandwidth of 575MHz. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 71.3dB and Spurious Free Dynamic Range (SFDR) of 90dB at the Nyquist frequency. It supports multiplexed or separate data buses, includes clock duty cycle stabilization, and utilizes a 64-pin 9mm x 9mm QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF confirms tape and reel packaging and lead-free compliance. Confirm the 'I' grade designation matches the required -40°C to 85°C operating temperature range for the specific application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 25Msps conversion speed. Compare against the LTC2292 (40Msps) and LTC2293 (65Msps) if higher throughput is needed. Ensure the system can accommodate the 64-pin QFN footprint and that the 3V supply voltage aligns with the design constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC229x family of dual 12-bit ADCs. It shares pin compatibility with other speeds in the series, including the LTC2290 (10Msps), LTC2292 (40Msps), and LTC2293 (65Msps). This allows for design flexibility across different sampling rate requirements within the same hardware layout.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the LTC2292IUP#TRPBF (40Msps) and LTC2293IUP#TRPBF (65Msps). These offer higher sampling rates while maintaining the same package and interface.
