- 0.8 W element power dissipation rating supporting higher current differential signal conditioning circuits
- Isolated network topology providing superior common-mode rejection in precision bridge and instrumentation amplifier applications
Applications
The LT5400BCMS8E-4#PBF is designed for precision analog signal conditioning circuits such as instrumentation amplifier gain-setting networks, differential ADC input dividers, and Wheatstone bridge completion. Its tightly matched 1 kΩ dual resistor pair maintains ratio accuracy over temperature extremes from -55°C to 125°C, making it ideal for industrial sensor interfaces and medical measurement equipment. Data acquisition systems and precision current sense circuits benefit from its low tracking error that minimizes offset and gain drift.

Frequently Asked Questions
How does the matched 1 kΩ dual network in LT5400BCMS8E-4#PBF improve instrumentation amplifier performance?
The LT5400BCMS8E-4#PBF provides two 1 kΩ resistor elements with matched temperature coefficients, ensuring the resistance ratio remains stable within a few ppm/°C over the operating range of -55°C to 125°C. This tight tracking minimizes gain drift in instrumentation amplifiers, reducing offset errors to below 1 µV/°C in precision bridge measurement circuits.
What power handling capability does LT5400BCMS8E-4#PBF offer and how does it affect circuit design choices?
Each element in the LT5400BCMS8E-4#PBF is rated for 0.8 W of power dissipation, allowing it to handle continuous currents up to 28 mA at the 1 kΩ resistance value. This power rating gives designers headroom for higher-voltage rails such as ±15 V analog supplies without thermal derating, making the part suitable for industrial analog front-ends operating at higher signal levels.
What mounting and package options are available for the LT5400BCMS8E-4#PBF for compact PCB layouts?
The LT5400BCMS8E-4#PBF is available in a surface-mount MSOP-8 small outline package, occupying a PCB footprint of approximately 3 mm x 3 mm. This compact 8-pin package enables close placement to the instrumentation amplifier input pins, reducing parasitic inductance on sensitive differential signal traces and improving common-mode rejection ratio above 1 MHz.
When is LT5400BCMS8E-4#PBF preferred over discrete 1% resistors for a differential signal divider?
The LT5400BCMS8E-4#PBF is preferred when ratio accuracy between 2 resistors must be maintained within 0.01% over a temperature range of -55°C to 125°C, which is impractical with separate 1% discrete resistors that can drift independently by up to 100 ppm/°C. A single matched network package also eliminates the layout mismatch of 2 discrete components placed millimeters apart on the PCB.
