LT6372HMSE-0.2#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT6372HMSE-0.2#PBF is a high precision funneling instrumentation amplifier featuring integrated level shifting and output clamping, designed for interfacing with analog-to-digital converters. It utilizes a proprietary bipolar process to achieve industry-leading DC precision, including a maximum input offset voltage of 60µV and a minimum common-mode rejection ratio of 80dB at G=0.2. The device offers a gain range from 0.2 to over 200 V/V via a single external resistor. Key electrical specifications include a 4MHz bandwidth at G=0.2, 11V/µs slew rate, and low noise density of 7nV/√Hz. It operates on supply voltages between 4.75V and 35V within the –40°C to 125°C temperature range.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the H-grade suffix indicates the extended temperature range of –40°C to 125°C. Confirm the MS16E package designation matches the required 16-lead plastic MSOP footprint. Ensure the ordering suffix #PBF denotes lead-free and RoHS compliance. Cross-reference the specific part number LT6372HMSE-0.2#PBF against current manufacturer availability lists as supply status may vary.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when interfacing large differential signals to single-ended ADCs requiring precise level shifting and protection. The H-grade variant is necessary for applications operating above 85°C up to 125°C. Consider the integrated clamping features if the system lacks external protection circuitry. Verify that the single-resistor gain setting capability aligns with the design's complexity constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT6372 family of funneling instrumentation amplifiers. The HMSE-0.2 designation specifically identifies the H-grade version in the MS16E package with a fixed gain factor of 0.2. It serves as an improved successor to earlier models by incorporating enhanced accuracy and simplified ADC interfacing features through monolithic construction and laser trimming.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the gain setting mechanism work?

The gain is set using a single external resistor connected between the +RG,S/-RG,S and +RG,F/-RG,F pins. The internal resistors are trimmed to ensure accurate gain settings across the range of 0.2 to >200 V/V.

What is the function of the CLLO and CLHI pins?

These pins provide integrated output clamping. The output voltage is limited to approximately 500mV below the CLLO voltage and 500mV above the CLHI voltage, protecting downstream ADC inputs from overvoltage conditions.
