Key Features
- Dual matched 1 MΩ isolated resistor network providing precise ratio accuracy for high-impedance analog gain stages
- 0.8 W element power dissipation in SOIC-8 surface-mount package enabling compact, stable precision analog PCB layouts
- REACH-compliant and isolated network topology suitable for differential measurement and bridge sensing applications
Applications
The LT5400ACMS8E-5#TRPBF is designed for high-impedance precision analog circuits such as electrometer amplifier feedback networks, precision voltage dividers in pH measurement, and differential sensing front-ends requiring 1 MΩ matched pairs. Its ratio-matched construction maintains gain accuracy in instrumentation amplifier configurations where discrete 1 MΩ resistors would introduce unacceptable mismatch. The SOIC-8 package integrates cleanly into multi-channel data acquisition boards with tight board real estate constraints.

Frequently Asked Questions
For high-impedance sensor interfaces, how does the 1 MΩ matched pair in the LT5400ACMS8E-5#TRPBF improve measurement accuracy?
The LT5400ACMS8E-5#TRPBF provides a dual 1 MΩ matched resistor pair that tracks together over temperature, maintaining ratio accuracy far better than two discrete 1 MΩ resistors from separate manufacturing lots. In electrometer or pH sensor front-ends where source impedance exceeds 100 kΩ, this ratio matching prevents gain error that would otherwise corrupt the microvolt-level signals being measured.
What power handling does the 0.8 W dissipation rating allow in typical 5 V rail circuits using the LT5400ACMS8E-5#TRPBF?
At 1 MΩ element resistance with a 0.8 W element power dissipation limit, the LT5400ACMS8E-5#TRPBF safely handles voltages up to approximately 894 V before exceeding its thermal limit, which is far beyond standard 5 V or 15 V analog rails. In practice, engineers should verify total package dissipation across both elements remains below 0.8 W per element under worst-case operating conditions.
How does the LT5400ACMS8E-5#TRPBF compare to using discrete 1 MΩ resistors in a precision voltage divider application?
Discrete 1 MΩ resistors typically carry 1% tolerance individually, leading to divider ratio errors up to 2% in worst-case combinations, whereas the LT5400ACMS8E-5#TRPBF guarantees matched ratio accuracy orders of magnitude tighter due to monolithic construction. For precision voltage dividers in 16-bit data acquisition systems, this eliminates the need for manual resistor selection or post-assembly gain calibration trimming.
