LT1993CUD-10#TRPBF

Overview

The LT1993CUD-10#TRPBF is a low distortion, low noise differential amplifier and ADC driver with a 700MHz bandwidth. It operates on a single 5V supply, consuming 100mA. The device features a fixed gain of 20dB (10V/V), differential inputs and outputs, and an adjustable output common mode voltage via the VOCM pin. It includes built-in 175MHz differential lowpass filtering on dedicated filtered outputs. Packaged in a compact 16-lead 3x3mm QFN, it supports DC to high-frequency signal processing.

Feature Summary

• Provides differential amplification with a fixed gain of 20dB for driving high-speed analog-to-digital converters.
• Integrates a 175MHz differential lowpass filter on dedicated outputs to reduce external component requirements.
• Features an adjustable output common mode voltage control pin to eliminate the need for output transformers or AC-coupling capacitors.
• Supports both DC and AC coupled operation with minimal required support circuitry.

Applications

• Differential ADC driver for imaging and communications systems
• Single-ended to differential conversion
• IF sampling receivers
• SAW filter interfacing and buffering

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging and lead-free compliance. Confirm the 'C' grade designation corresponds to the specified operating temperature range and performance guarantees. Ensure the order quantity matches the reel specifications provided by the manufacturer.

Selection Notes

Select this component when a fixed 20dB gain and wide bandwidth are required for driving high-resolution ADCs. Consider the integrated filtering if reducing board space for external components is a priority. Verify that the 5V single-supply operation aligns with the system power architecture.

Part Context

This part belongs to the LT1993 series of differential amplifiers designed for high-speed data acquisition. It serves as a bridge between analog front-end signals and digital conversion stages, offering high linearity and low noise characteristics essential for maintaining signal integrity in demanding RF and IF applications.
