LT6350HMS8#TRPBF

Overview

The LT6350HMS8#TRPBF is a low noise single-ended to differential converter and ADC driver featuring rail-to-rail input and output capabilities. It converts high or low impedance single-ended signals into balanced differential outputs suitable for driving SAR ADCs. The device operates on a 2.7V to 12V supply, drawing 4.8mA at 5V. Key electrical parameters include a 33MHz -3dB bandwidth, 1.9nV/√Hz input-referred voltage noise, and ±400µV maximum offset voltage. It offers fast settling time (240ns to 0.01%) and low distortion (-102dBc HD2 at 100kHz). The component is housed in an 8-lead MSOP package and functions within a temperature range of –40°C to 125°C.

Feature Summary

• Converts single-ended inputs to differential outputs with rail-to-rail performance
• Features very low input-referred noise and high DC linearity
• Includes internal gain resistors eliminating external components
• Supports low power shutdown mode

Applications

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

Procurement Notes

Verify the specific suffix 'H' corresponds to the extended industrial temperature range of –40°C to 125°C as defined in the ordering information. Confirm the 'MS8' designation matches the required 8-lead plastic MSOP package type. Ensure the '#TRPBF' suffix indicates the tape and reel packaging format. Cross-reference the manufacturer's current datasheet for any updates regarding lead-free finish specifications or RoHS compliance status prior to final procurement.

Selection Notes

Select this component when interfacing high impedance single-ended sources to differential analog-to-digital converters requiring high dynamic range. The internal gain structure simplifies design by removing external feedback resistors. Consider the rail-to-rail input/output capability for maximizing signal swing from single-supply systems. Evaluate the shutdown feature if system power management requires minimizing quiescent current during idle periods.

Part Context

This part belongs to the LT6350 family of precision analog front-end devices designed specifically for data acquisition systems. The series provides integrated solutions for converting unbalanced signals to balanced formats while maintaining signal integrity. The H-grade variant ensures reliable operation across wider environmental conditions compared to commercial or industrial grades, making it suitable for demanding applications.

Replacement Considerations

LT6350HDD#TRPBF: Same electrical specifications and temperature range but utilizes an 8-lead DFN package instead of MSOP.
