LT1993CUD-2#TRPBF

Overview

The LT1993CUD-2#TRPBF is a low distortion, low noise differential amplifier and ADC driver from Analog Devices Inc. It operates on a single 5V supply with typical current consumption of 100mA. The device features a fixed gain of 6dB (2V/V) and an 800MHz -3dB bandwidth. It includes built-in 175MHz differential low-pass filtering at dedicated filtered outputs. The component is housed in a compact 16-lead 3mm x 3mm QFN package.

Feature Summary

• Provides differential amplification with integrated low-pass filtering to reduce external component requirements for high-speed ADC driving.
• Features adjustable output common mode voltage control via the VOCM pin, eliminating the need for output transformers or AC-coupling capacitors.
• Supports both DC and AC coupled operation with minimal support circuitry required for implementation.

Applications

• Differential ADC Driver for imaging and communications systems
• IF Sampling Receivers
• SAW Filter Interfacing and Buffering

Procurement Notes

Verify that the ordering suffix #TRPBF corresponds to the Tape and Reel packaging format as specified in the manufacturer documentation. Confirm the 'C' grade designation aligns with the required operational temperature range specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring a fixed 6dB gain with high linearity and low noise figures. Ensure the application benefits from the integrated 175MHz filtering capability to simplify board layout. Verify that the 5V single-supply requirement fits within the system power budget constraints.

Part Context

This part belongs to the LT1993 family of differential amplifiers designed specifically for driving high-speed analog-to-digital converters. It serves as a general-purpose differential gain block suitable for applications demanding high performance across a wide frequency range.

Replacement Considerations

Consult official documentation for confirmed substitute part numbers. Do not assume functional equivalence with other series components without verifying electrical parameter alignment.
