LTC1744IFW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1744IFW#TRPBF is a 50Msps, 14-bit pipelined analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates on a single 5V supply and dissipates approximately 1.2W of power. The device features selectable differential input ranges of –1V or –1.6V via the SENSE pin. Key performance metrics include a signal-to-noise ratio (SNR) of up to 77dB and a spurious-free dynamic range (SFDR) of up to 87dB in the 3.2V range. It utilizes a 48-lead TSSOP package and supports an industrial temperature range from –40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• 50Msps sampling rate with 14-bit resolution and no missing codes
• Selectable differential input ranges: –1V (SENSE grounded) or –1.6V (SENSE tied to VDD)
• Ultralow aperture jitter of 0.3ps RMS for high-frequency undersampling
• Digital interface compatible with 5V, 3V, and 2V logic systems

Analog To Digital Converters (ADC) Applications

• Telecommunications base stations
• Wireless receivers
• Spectrum analysis equipment
• Imaging systems

Analog To Digital Converters (ADC) Procurement Notes

Verify that the #TRPBF suffix indicates tape-and-reel packaging. Confirm the IFW variant meets the required –40°C to +85°C operating temperature range. Ensure the source document explicitly lists this part number as available from authorized distributors.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1744IFW#TRPBF when a 50Msps sampling rate and 14-bit resolution are required. Choose the I-grade version for industrial temperature applications. Verify that the system can accommodate the 1.2W power dissipation and provides adequate bypassing for the 5V analog supply and variable OVDD.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC174x family of high-speed ADCs. It is pin-compatible with other members such as the LTC1743 (12-bit), LTC1745 (12-bit at 25Msps), and LTC1746 (14-bit at 25Msps). This allows for design flexibility across different speed and resolution requirements within the same footprint.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the LTC1743CFW#TRPBF (12-bit, 50Msps) and LTC1746CFW#TRPBF (14-bit, 25Msps). Verify that the lower resolution or sampling rate of these alternatives meets the specific application requirements.
