LTC2298IUP#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2298IUP#TRPBF is a dual-channel, 14-bit analog-to-digital converter (ADC) operating at a sampling rate of 65Msps. It utilizes a single 3V supply (2.7V to 3.4V) and dissipates 400mW. The device features a pipeline architecture with a 575MHz full-power bandwidth sample-and-hold circuit. Key performance metrics include a signal-to-noise ratio (SNR) of 74.3dB and a spurious-free dynamic range (SFDR) of 90dB at the Nyquist frequency. It offers flexible input ranges from ±0.5V to ±1V and supports both multiplexed and separate digital output buses.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates a lead-free tape and reel packaging configuration. Confirm the I-grade designation corresponds to an industrial temperature range of -40°C to 85°C. Ensure the QFN-64 package dimensions match the PCB footprint requirements for the 9mm x 9mm plastic housing.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel conversion is required at 65Msps with 14-bit resolution. Compare against the LTC2297 (40Msps) or LTC2296 (25Msps) if lower power consumption is prioritized over speed. Ensure the application can accommodate the 400mW power dissipation and provides adequate thermal management for the exposed pad ground connection.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC229x family of low-power 3V ADCs. It is pin-compatible with the LTC2297 and LTC2296, which offer reduced sampling rates of 40Msps and 25Msps respectively. The family also includes 12-bit variants such as the LTC2293 and LTC2292, allowing for design flexibility across different resolution and speed requirements within the same package.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2297IUP#TRPBF and LTC2296IUP#TRPBF are pin-compatible alternatives offering lower sampling rates of 40Msps and 25Msps, respectively. These may be suitable if system timing allows for reduced throughput in exchange for lower power consumption.
