Frequently Asked Questions
What is the input bias current of the LMC7111BIM5?
The LMC7111BIM5 features an extremely low maximum input bias current of 0.000001 µA (1 fA), and a maximum input offset current of 0.00001 µA. This makes it ideal for high-impedance sensor interfaces such as photodiode amplifiers and pH measurement circuits where leakage current must be minimized.
What package does the LMC7111BIM5 come in and what are its dimensions?
The LMC7111BIM5 is housed in a SOT-23-5 package (5-pin small-outline transistor), which is a compact surface-mount package. This space-saving footprint makes it suitable for portable devices, wearables, and other space-constrained PCB designs where minimizing board area is a priority.
What applications is the LMC7111BIM5 best suited for?
The LMC7111BIM5 is optimized for precision, low-power applications including portable medical instruments, handheld meters, IoT sensors, and battery-powered systems. Its 85 dB typical CMRR, 3 mV max input offset voltage, and rail-to-rail output make it excellent for signal conditioning, transducer amplification, and precision voltage comparators.
What is the common-mode rejection ratio (CMRR) of the LMC7111BIM5?
The LMC7111BIM5 has a minimum CMRR of 60 dB and a typical CMRR of 85 dB. This high common-mode rejection ensures the amplifier effectively suppresses noise and interference that appears simultaneously on both input terminals, making it well-suited for differential signal acquisition in noisy industrial and medical environments.
