LT6350IMS8#PBF

Overview

The LT6350IMS8#PBF 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 supply voltages ranging from 2.7V to 12V, drawing 4.8mA at 5V. It provides high DC linearity (<±1LSB for 16-bit) and low harmonic distortion (-102dBc HD2 at 100kHz). The component is housed in an 8-lead MSOP package and supports operation over the -40°C to 85°C temperature range.

Feature Summary

• Converts single-ended signals to balanced differential outputs suitable for driving SAR ADCs
• Features rail-to-rail input and output stages for maximum dynamic range
• Includes internal feedback resistors eliminating the need for external gain components
• Offers low power shutdown mode reducing current consumption 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 IMS8 corresponds to the 8-lead MSOP package variant. Confirm the temperature grade matches the required operational environment, as other suffixes indicate different ranges. Ensure the #PBF designation aligns with lead-free compliance requirements for the target assembly process.

Selection Notes

Select this component when a low noise, high-speed interface between single-ended sources and differential ADCs is required. The integrated resistor network simplifies layout compared to discrete solutions. Consider the 33MHz bandwidth and settling time for high-frequency signal acquisition systems requiring precise common-mode control via the +IN2 pin.

Part Context

This part belongs to the LT6350 family of analog interface devices designed for precision data acquisition. The IMS8 suffix specifically denotes the industrial temperature grade version packaged in an 8-lead Mini Small Outline Package (MSOP), distinguishing it from the DFN or commercial grade variants within the same functional series.
