LTC6405CUD#TRPBF

Overview

The LTC6405CUD#TRPBF is a low noise, low distortion fully differential amplifier optimized for 5V single supply operation. It features a 2.7GHz gain-bandwidth product and an 800MHz -3dB bandwidth with unity gain. The device offers rail-to-rail input common mode range and adjustable output common mode voltage via the VOCM pin. It draws 18mA at 5V and includes a hardware shutdown feature reducing current to 400µA. The component operates from 4.5V to 5.25V in a 16-lead 3mm x 3mm QFN package.

Feature Summary

• Fully differential input and output architecture providing even-order harmonic cancellation.
• Rail-to-rail input common mode range compatible with wide signal swings.
• Adjustable output common mode voltage independent of input common mode level.
• Hardware shutdown capability for significant power reduction.

Applications

• Differential input ADC driver for 12-bit to 16-bit converters
• Single-ended to differential conversion with common mode level shifting
• High-linearity direct conversion receivers

Procurement Notes

Verify the specific temperature grade suffix 'C' indicates a commercial operating range of 0°C to 70°C, distinct from the industrial 'I' grade. Confirm the '#TRPBF' suffix denotes tape and reel packaging. Ensure the source documentation explicitly supports the requested configuration before finalizing procurement specifications.

Selection Notes

Select this component when driving single-supply differential ADCs requiring level shifting. The adjustable VOCM pin allows precise output centering. Verify that the 5V supply range and 18mA quiescent current align with system power constraints. Consider the QFN package thermal characteristics for high-frequency applications.

Part Context

This part belongs to the LTC6405 family of wideband differential amplifiers. The 'C' designation specifies the commercial temperature range variant. The 'UD' indicates the 16-lead QFN package format. This series is designed for high-speed data acquisition systems requiring low noise and high linearity.
