LTC1742CFW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1742CFW#PBF is a 14-bit, 65Msps pipelined analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates on a single 5V supply and dissipates approximately 1.275W of power. The device features a selectable differential input range of –1V or –1.6V, determined by the SENSE pin configuration. Key performance metrics include a signal-to-noise ratio (SNR) of 76.5dB at 5MHz with a 3.2V range and 90dB spurious-free dynamic range (SFDR). It utilizes a 48-lead TSSOP package and supports digital interfaces compatible with 5V, 3V, 2V, and LVDS logic levels.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as indicated in official documentation. Check for end-of-life notifications or obsolescence warnings prior to procurement. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1742CFW#PBF for applications requiring 65Msps throughput with 14-bit precision. Choose this model over the LTC1742IFW#PBF if the operating environment remains within 0°C to 70°C. Ensure the design accommodates the 1.275W power dissipation and provides adequate thermal management for the TSSOP package.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1742 family of high-speed ADCs. It is pin-compatible with other members of the series, including the 25Msps LTC1746, 50Msps LTC1744, and 80Msps LTC1748. This compatibility allows for design flexibility across different bandwidth requirements while maintaining the same footprint.

Analog To Digital Converters (ADC) Replacement Considerations

For direct pin-compatible replacements within the same speed class, consider the LTC1742IFW#PBF for extended temperature ranges. For lower speed requirements, the LTC1746 (25Msps) or LTC1744 (50Msps) may serve as alternatives.
