LTC1741IFW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1741IFW#PBF 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 incorporates an ultralow jitter sample-and-hold circuit of 0.15ps RMS to support undersampling applications.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature grade. The IFW designation indicates an industrial temperature range (-40°C to 85°C) and a 48-lead TSSOP package. Confirm RoHS compliance status through official datasheets prior to procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1741IFW#PBF when a 65Msps sampling rate and 12-bit resolution are required for wide dynamic range signals. Ensure the application can accommodate the 1.275W power dissipation and provides adequate thermal management. Verify that the system clock jitter remains below 0.15ps RMS to maintain specified SNR performance.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC174x family of low noise ADCs. It is pin-compatible with other members such as the LTC1742 (14-bit), LTC1743 (12-bit), and LTC1744 (14-bit). These variants offer different combinations of resolution and sampling speeds ranging from 25Msps to 80Msps within the same package footprint.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1741IFE#PBF serves as a direct replacement offering identical electrical specifications in a 20-lead TSSOP-EP package. Designers must account for the significant difference in pin count and physical dimensions when substituting this part.
