LT1993IUD-2#TRPBF

Overview

The LT1993IUD-2#TRPBF is an industrial grade, low distortion, low noise differential amplifier and ADC driver from Analog Devices. It features a fixed gain of 6dB (2V/V) and operates with a single 5V supply consuming 100mA. The device provides both unfiltered outputs and integrated filtered outputs with a 175MHz cutoff to reduce external components. It utilizes a compact 16-lead 3mm x 3mm QFN package and supports operation across the -40°C to 85°C temperature range.

Feature Summary

• Integrated 175MHz differential low-pass filter on dedicated output pins
• Adjustable output common mode voltage via VOCM pin
• Supports DC-coupled or AC-coupled input configurations
• TTL-compatible enable pin for power management

Applications

• Differential ADC driver for high-speed data acquisition systems
• IF sampling receivers in communications transceivers
• SAW filter interfacing and buffering
• Single-ended to differential signal conversion

Procurement Notes

Verify the specific 'I' suffix indicates the industrial temperature range (-40°C to 85°C) rather than the commercial variant. Confirm the '#TRPBF' designation ensures lead-free composition and tape-and-reel packaging format. Cross-reference the manufacturer datasheet to ensure compatibility with your system's power supply and logic levels.

Selection Notes

Select this component when driving 12-bit or 14-bit ADCs requiring minimal support circuitry. The fixed 2V/V gain simplifies design compared to programmable amplifiers. Ensure the application benefits from the built-in filtering to save board space. Verify that the 5V single-supply requirement aligns with the target system architecture.

Part Context

This part belongs to the LT1993-2 family of differential amplifiers designed for high-frequency applications. The 'I' suffix denotes the industrial temperature grade, while 'UD' specifies the 16-lead QFN package type. The '#TRPBF' suffix confirms it is a lead-free product supplied in a tape-and-reel configuration for automated assembly.

Replacement Considerations
