LT6350IMS8#TRPBF

Overview

The LT6350IMS8#TRPBF is a low noise single-ended to differential converter and ADC driver manufactured by Analog Devices. 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 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 125°C.

Feature Summary

• Converts high or low impedance single-ended signals into balanced differential outputs for driving SAR ADCs
• Features fast settling time and very low noise op amps supporting SNR greater than 110dB
• 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 TRPBF indicates tape and reel packaging when sourcing this component. Confirm the IMS8 designation corresponds to the 8-lead MSOP package variant rather than the DFN option. Ensure the temperature grade matches the required operational range for your design environment before finalizing procurement orders.

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 48V/µs slew rate for signal fidelity requirements. Evaluate the 4.8mA supply current against system power constraints.

Part Context

This part belongs to the LT6350 family of precision analog converters. It serves as a bridge between sensor outputs and data acquisition systems.

FAQ

How is the output common mode voltage determined?

The output common mode voltage is set by applying a voltage directly to the +IN2 pin.

What is the maximum differential output swing on a single 5V supply?

On a single 5V supply, the outputs can swing from 55mV to 4.945V, allowing for approximately 8VP-P differential outputs.
