LTC1744CFW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1744CFW#PBF is a 14-bit, 50Msps 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 77dB and spurious-free dynamic range (SFDR) of 87dB with a 3.2V range at a 5MHz input frequency. It utilizes a parallel digital interface compatible with 5V, 3V, and 2V logic systems.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices from Analog Devices, as this part may be subject to production lifecycle changes. Ensure proper handling for ESD-sensitive components during procurement and storage.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1744CFW#PBF when a 50Msps sampling rate and 14-bit resolution are required. Choose this model over the LTC1745 (12-bit) or LTC1746 (25Msps) if higher bandwidth and precision are necessary. Ensure the application supports the 1.2W power dissipation and requires a single 5V analog supply. Verify that the parallel interface matches the target DSP or FPGA capabilities.

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), LTC1742 (14-bit, 65Msps), and LTC1748 (14-bit, 80Msps). This allows for design flexibility within the same package footprint while adjusting for speed or resolution requirements.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible substitutes within the same family include the LTC1742IFW (65Msps, 14-bit) and LTC1748IFW (80Msps, 14-bit). For lower speed requirements, the LTC1746IFW (25Msps, 14-bit) is an option. Verify that the replacement's timing parameters and power consumption fit the existing board design.
