LT6411CUD#PBF

Overview

The LT6411CUD#PBF is a dual amplifier with individually selectable gains of +1, +2, and –1. It features a 650MHz small-signal bandwidth and a 3300V/µs slew rate. The device operates on split supplies up to ±6V or a single supply as low as 4.5V. Each amplifier draws 8mA quiescent current when enabled. It is housed in a 3mm × 3mm 16-pin QFN package.

Feature Summary

• Individually configurable gain settings of +1, +2, and –1 without external resistors
• High-speed performance with 650MHz bandwidth and 3300V/µs slew rate
• Low power consumption with 8mA per amplifier and shutdown mode under 350µA
• Integrated enable control for system power management

Applications

• Differential ADC driver
• Single-ended to differential conversion
• Differential video line driver

Procurement Notes

Verify the specific temperature grade suffix 'C' against application requirements, as it differs from the industrial grade 'I'. Confirm the lead-free '#PBF' designation matches environmental compliance standards. Ensure the 16-pin QFN footprint aligns with PCB layout capabilities. Validate that the operating voltage range meets system specifications.

Selection Notes

Select this component for high-speed signal conditioning requiring precise gain configuration. Consider the thermal characteristics of the exposed pad connected to VEE. Evaluate the input common-mode voltage range relative to the supply rails. Assess the need for channel isolation and crosstalk performance in dense layouts.

Part Context

This part belongs to the LT6411 family of dual amplifiers designed for driving analog-to-digital converters. It utilizes a proprietary low-voltage complementary bipolar process. The series offers high distortion performance and wide bandwidth suitable for demanding data transmission applications.
