LT6350IDD#TRPBF

Overview

The LT6350IDD#TRPBF is a low noise single-ended to differential converter and ADC driver manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities with a gain-bandwidth product of 33 MHz and a slew rate of 48 V/µs. The device operates on a supply voltage range of 2.7V to 12V, drawing 4.8mA at 5V. It provides an input-referred voltage noise density of 1.9 nV/√Hz and input current noise of 1.1 pA/√Hz. The component is housed in an 8-lead MSOP package and supports operation from -40°C to 85°C.

Feature Summary

• Features rail-to-rail input and output stages with fast settling time
• Includes internal matched thin-film resistors eliminating the need for external gain components
• Offers low power shutdown mode reducing supply current significantly

Applications

• Driving 16-bit and 18-bit SAR ADCs
• Single-ended to differential conversion circuits
• Differential line drivers

Procurement Notes

Verify the specific suffix IDD#TRPBF confirms the industrial temperature grade (-40°C to 85°C) and tape-and-reel packaging format. Confirm the manufacturer is Analog Devices Inc. Ensure the part matches the 8-lead MSOP physical footprint. Cross-reference the datasheet revision to ensure electrical characteristics align with design requirements.

Selection Notes

Select this component when a low noise, high speed interface between single-ended sources and differential ADCs is required. The internal resistor network simplifies layout compared to discrete solutions. Consider the 33MHz bandwidth and 48V/µs slew rate for signal fidelity. Verify that the 4.8mA supply current fits the system power budget and that the MSOP package accommodates the thermal constraints of the application.
