LTC6406IUD#PBF

Overview

The LTC6406IUD#PBF is a 3GHz, low noise, rail-to-rail input differential amplifier/driver optimized for 3V single supply operation. It features a gain-bandwidth product of 3GHz and a -3dB bandwidth extending to 800MHz at unity gain. The device draws 18mA with a hardware shutdown feature reducing current to 300μA. It operates over a supply voltage range of 2.7V to 3.5V and an industrial temperature range of –40°C to 85°C. The component is housed in a compact 3mm × 3mm 16-lead QFN package.

Feature Summary

• Rail-to-rail differential input capability allows full signal swing across the entire supply range.
• Adjustable output common mode voltage via VOCM pin enables precise level-shifting for ADC interfaces.
• Hardware shutdown pin reduces power consumption significantly when the device is inactive.
• Fully differential architecture provides even-order harmonic cancellation and improved noise immunity.

Applications

• Differential input ADC driver
• Single-ended to differential conversion
• Level-shifting ground-referenced signals
• High linearity direct conversion receivers

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging. Confirm the 'I' grade designation matches the required –40°C to 85°C operating temperature range. Ensure the QFN-16 package footprint aligns with the PCB layout specifications provided in the datasheet pin configuration diagrams.

Selection Notes

Select this component for applications requiring high linearity and low noise in a single-supply environment. The adjustable output common mode voltage makes it suitable for interfacing with various ADC input ranges. Consider the 3GHz bandwidth for wideband signal processing needs where distortion performance at higher frequencies is critical.

Part Context
