- Ultra-low bias current of 2.6 µA max at 25°C, minimizing loading effects in high-impedance sensor interfaces
- Built-in frequency compensation for stable closed-loop operation across a wide range of gain configurations
- Input offset voltage of 7 mV max, suitable for precision analog front-end and measurement applications
Applications
The LMH6640MF is well-suited for precision signal conditioning in data acquisition systems, medical instrumentation, and industrial sensor interfaces. Its low bias current and high CMRR make it ideal for amplifying weak signals from high-impedance sources such as pH probes, strain gauges, and thermocouple circuits. It also finds use in active filter designs, audio processing, and test-and-measurement equipment where stable, low-noise amplification is critical.
