LTC6410CUD-6#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC6410CUD-6#TRPBF is a low distortion, low noise differential IF amplifier with configurable input impedance designed for applications from DC to 1.4GHz. It features a fixed voltage gain of 6dB in a 50Ω system and an active input termination allowing customized input impedance for optimal interface to differential active mixers. The device operates on 3V or 5V supplies within a 2.8V to 5.25V range, comes in a compact 16-lead 3mm × 3mm QFN package, and operates over a –40°C to 85°C temperature range.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Configurable input impedance allows simple interface to active mixers and improved noise performance compared to traditional 50Ω interfaces.
• Low distortion characteristics suitable for driving SAW filters and other 50Ω signal chain blocks directly.
• Self-biasing inputs and outputs minimize support circuitry requirements.
• Shutdown mode capability reduces supply current significantly.

Instrumentation, Op Amps, Buffer Amps Applications

• Post-mixer gain block
• SAW filter interface and buffering
• Differential IF signal chain gain block
• Differential line driver/receiver

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the C grade meets the required operating temperature range of –40°C to 85°C for your application environment. Ensure the 16-lead QFN footprint matches your PCB layout constraints. Check for any lead-free compliance documentation if required by your manufacturing standards.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when interfacing active mixers requiring higher input impedance than standard 50Ω systems. Consider the trade-off between noise figure and power gain when configuring external termination resistors. Evaluate the shutdown pin logic levels against your control voltage availability. Verify that the supply voltage range accommodates your system's power rail variations.
