Frequently Asked Questions

What is the CMRR specification of the INA111BP?

The INA111BP offers a minimum common-mode rejection ratio (CMRR) of 106 dB, ensuring excellent rejection of common-mode noise and interference. This makes it highly suitable for precision differential signal amplification in noisy industrial and medical environments.

What are the typical applications for the INA111BP instrumentation amplifier?

The INA111BP is commonly used in medical instrumentation (ECG, EEG), industrial data acquisition, bridge sensor amplification (strain gauges, pressure sensors), thermocouple signal conditioning, and precision test and measurement equipment. Its low bias current of 20 pA max makes it ideal for high-impedance source applications.

What package type does the INA111BP use and is it RoHS compliant?

The INA111BP comes in an 8-Pin PDIP (Dual In-Line Package) through-hole package, making it easy to prototype and assemble on standard PCBs. It is Pb-free (RoHS compliant) as indicated by its Pbfree Code, suitable for modern environmentally conscious designs.

What is the bandwidth of the INA111BP and how does it affect signal amplification?

The INA111BP has a 3dB bandwidth of 2 MHz, which allows accurate amplification of signals up to 2 MHz without significant attenuation. This bandwidth is sufficient for most precision measurement and industrial sensor applications while maintaining low noise performance.
