Analog Devices Inc. LT6372HMSE-0.2#PBF

Overview

LT6372HMSE-0.2#PBF from Analog Devices is a precision funneling instrumentation amplifier with integrated output clamping and level-shift capability, designed for high-accuracy signal conditioning in harsh industrial and medical environments. It delivers 60µV max input offset voltage, 80dB min DC CMRR at G = 0.2, and 4MHz –3dB bandwidth (G = 0.2), enabling ±10V bridge or thermocouple signals to be safely conditioned into a 5V ADC input range.

For engineers reviewing the LT6372HMSE-0.2#PBF datasheet, LT6372HMSE-0.2#PBF pinout, LT6372HMSE-0.2#PBF application, or LT6372HMSE-0.2#PBF equivalent, this H-grade MSOP-16 device supports –40°C to 125°C operation, features split-reference level shifting, on-chip RFI filtering, and dual clamp inputs for robust ADC interface protection in data acquisition systems.

Technical Context

The LT6372HMSE-0.2#PBF implements a laser-trimmed, three-op-amp instrumentation topology using a proprietary bipolar process to achieve ultra-low drift and long-term stability. Its preamp stage uses matched NPN transistors Q1/Q2 with trimmed collector currents to minimize input offset voltage drift (0.6µV/°C max).

It incorporates a split-reference difference amplifier stage that enables precise output level shifting via REF1/REF2 pins, and dedicated CLHI/CLLO terminals that actively clamp output voltage to user-defined limits-typically ±0.5V relative to applied clamp voltages-with guaranteed clamp thresholds across temperature.

Key Specifications

Pinout & Package

LT6372HMSE-0.2#PBF is housed in a 16-lead plastic MSOP (MSE) package with exposed pad (Pin 17), rated for –40°C to 125°C operation. The exposed pad must float or connect to V+ (Pin 12) per datasheet thermal guidelines.

FAQ

What is the maximum operating temperature for the LT6372HMSE-0.2#PBF?

The LT6372HMSE-0.2#PBF is specified for continuous operation from –40°C to +125°C ambient temperature, meeting the H-grade qualification standard. Its internal junction temperature is limited to 150°C, and thermal design must account for θJA = 35°C/W in the MSOP package with proper PCB copper pour and exposed pad connection.

How does the LT6372HMSE-0.2#PBF implement output clamping without external components?

The LT6372HMSE-0.2#PBF uses internal active clamp circuitry referenced to CLHI and CLLO pins. When the output exceeds CLHI + 0.45V or falls below CLLO – 0.74V (over temperature), internal transistors limit current flow - ensuring the output stays within safe bounds for downstream ADCs without diodes or resistors.

Can the LT6372HMSE-0.2#PBF be used with single-supply operation?

Yes - the LT6372HMSE-0.2#PBF supports total supply voltages from 4.75V to 35V, including single-ended configurations such as +5V/V– = 0V or +24V/V– = 0V. Output swing extends to V– + 1.4V and V+ – 1.4V, and REF1/REF2 can be biased to set output mid-point for unipolar ADCs.

What is the purpose of the dual gain-set pins (e.g., +RG,S and +RG,F)?

The LT6372HMSE-0.2#PBF uses separate sense (S) and force (F) pins for both positive and negative gain-setting paths to enable Kelvin (four-wire) connection of RG. This eliminates errors from PCB trace resistance and solder joint variance - critical for maintaining <0.012% gain error at G = 0.2.

Does the LT6372HMSE-0.2#PBF require external filtering for EMI immunity?

No - the LT6372HMSE-0.2#PBF integrates RFI filters on both +IN and –IN inputs, verified to maintain 80dB CMRR in presence of 20kHz–100MHz RF interference. This eliminates need for external RC filters in most industrial environments, reducing component count and board area.
