LTC1741IFW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1741IFW#TRPBF is a 12-bit, 65Msps pipelined analog-to-digital converter (ADC) from Analog Devices Inc. It operates on a single 5V supply and dissipates approximately 1.275W. The device features selectable differential input ranges of –1V or –1.6V via the SENSE pin. Key performance metrics include 72dB SNR and 85dB SFDR at a 3.2V range with a 5MHz input signal. It exhibits ultralow jitter of 0.15ps RMS and supports digital interfaces compatible with 5V, 3V, 2V, and LVDS logic systems through its OVDD supply.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the 'I' grade designation corresponds to the –40°C to +85°C operating temperature range required for the application environment. Cross-reference the manufacturer part number with official Analog Devices documentation to ensure authenticity and correct revision level.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1741IFW#TRPBF for applications requiring high-speed digitization of wide dynamic range signals. Ensure the source impedance is matched to 50Ω for optimal SFDR performance. Verify that the external reference circuitry can support the required bypass capacitance values as specified in the datasheet to maintain stability and noise performance.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1741 family of high-speed ADCs. It is pin-compatible with other members such as the LTC1746 (14-bit, 25Msps), LTC1745 (12-bit, 25Msps), and LTC1744 (14-bit, 50Msps). This allows for design flexibility within the same package footprint while adjusting for speed and resolution requirements.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible substitutes within the same family include the LTC1741CFW#TRPBF for commercial temperature range applications. Other family members like the LTC1742 or LTC1743 offer different bit-depth or speed characteristics but share the same 48-pin TSSOP outline.
