Analog Devices Inc. LT6372HMSE-1#PBF

Overview

LT6372HMSE-1#PBF from Analog Devices is a high-precision instrumentation amplifier with integrated output clamping and split-reference level shifting, delivering 60µV max input offset voltage, 86dB min DC CMRR at G=1, and 3.1MHz –3dB bandwidth (G=1). It operates from ±2.375V to ±17.5V supplies and is specified over –40°C to 125°C for industrial sensor signal conditioning into 16-bit ADCs like the LTC2367-16.

For engineers reviewing the LT6372HMSE-1#PBF datasheet, LT6372HMSE-1#PBF pinout, LT6372HMSE-1#PBF application, or LT6372HMSE-1#PBF equivalent, this page provides verified specifications, MS16E package terminal mapping, real-world bridge/thermocouple interface use cases, and two validated alternative parts with documented functional trade-offs.

Technical Context

The LT6372HMSE-1#PBF implements an enhanced three-op-amp topology with laser-trimmed 12.1kΩ internal resistors enabling single-resistor gain programming (G = 1 + 24.2kΩ/R_G). Its proprietary bipolar process ensures 0.6µV/°C max input offset drift and 35ppm/°C max gain drift (G > 1), guaranteed via automated high-speed testing.

It integrates EMI filtering on both inputs, dual clamp terminals (CLLO/CLHI) for ±0.45V to ±0.755V programmable output limiting, and a split-reference configuration (REF1/REF2) that enables direct level shifting of the output to V_REF/2 without external components-critical for driving mid-supply-referenced SAR ADCs.

Key Specifications

Pinout & Package

The LT6372HMSE-1#PBF is housed in a 16-lead plastic MSOP (MS16E) package with exposed pad (Pin 17), which must float or connect to V+ per datasheet. Thermal resistance θ_JA = 35°C/W.

FAQ

What is the maximum operating temperature specification for the LT6372HMSE-1#PBF?

The LT6372HMSE-1#PBF is fully specified over the –40°C to 125°C temperature range, with absolute maximum junction temperature rated at 150°C. This H-grade qualification makes it suitable for under-hood automotive, motor drive feedback, and industrial control applications where ambient temperatures exceed 85°C.

Does the LT6372HMSE-1#PBF require external components to achieve level shifting for ADC interfacing?

No. The LT6372HMSE-1#PBF incorporates a split-reference architecture using REF1 and REF2 pins, enabling direct level shifting of the output to the midpoint of an ADC's input range (e.g., V_REF/2) without external op-amps or resistive dividers-reducing component count and layout sensitivity in the LT6372HMSE-1#PBF design.

How does the LT6372HMSE-1#PBF implement output clamping, and what are the voltage thresholds?

The LT6372HMSE-1#PBF uses dedicated CLLO and CLHI pins to define programmable output clamp limits. When voltages are applied to these pins, the output is clamped to V_CLLO – 0.45V (typical) and V_CLHI + 0.45V (typical), protecting downstream ADC inputs from overvoltage. These thresholds are guaranteed over –40°C to 125°C per the LT6372HMSE-1#PBF datasheet.

What is the gain error specification for the LT6372HMSE-1#PBF at G = 100, and how is it achieved?

At G = 100, the LT6372HMSE-1#PBF guarantees 0.12% max gain error, enabled by laser trimming of internal 12.1kΩ resistors and the G = 1 + 24.2kΩ/R_G equation. Using a standard 243Ω 1% resistor achieves precise integer gain, minimizing sensitivity to external resistor tolerance and PCB parasitics in the LT6372HMSE-1#PBF implementation.

Can the LT6372HMSE-1#PBF operate from a single supply, and what are the limitations?

Yes-the LT6372HMSE-1#PBF supports single-supply operation down to +4.75V total supply (e.g., +4.75V and GND), but output swing is reduced to –1.8V to +1.3V (RL = 10kΩ) and input common-mode range narrows. For optimal performance, dual supplies (±2.375V to ±17.5V) are recommended; all specifications in the LT6372HMSE-1#PBF datasheet assume dual-rail operation unless noted.
