Frequently Asked Questions
How does the 0.00001 µA input bias current of LMC6574BIM benefit high-impedance sensor interfaces?
With an input bias current of only 0.00001 µA (10 pA), the LMC6574BIM introduces negligible voltage error even when driven from a 1 MΩ source impedance, producing less than 10 µV of offset error. This makes it ideal for photodiode, pH electrode, and pyroelectric sensor interfaces where picoampere-level leakage is critical to measurement accuracy.
What CMRR does the LMC6574BIM deliver and which noise rejection scenarios does this support?
The LMC6574BIM provides a 75 dB typical CMRR (57 dB minimum), meaning a 1 V common-mode signal appears as roughly 178 µV at the output. This level of rejection is adequate for rejecting 50 Hz and 60 Hz power-line interference in medical ECG front ends, audio instrumentation, and industrial bridge measurement circuits.
Can LMC6574BIM operate from a single 3.3 V supply in a portable data-logging design?
Yes. The LMC6574BIM is a CMOS op amp rated for low single-supply operation, and its rail-to-rail output allows signal swings within millivolts of both supply rails even at 3.3 V. This characteristic maximizes dynamic range and ADC utilization in battery-powered data loggers and portable sensor nodes running from a single Li-ion cell.
With a YTEOL of 0 for LMC6574BIM, what sourcing strategy should procurement teams follow?
A YTEOL of 0 years indicates the LMC6574BIM is at or near end-of-life status. Procurement teams should immediately qualify a pin-compatible replacement such as the LMC6574A or another quad CMOS rail-to-rail op amp in the same package. Last-time-buy orders should be placed based on at least 24 months of projected consumption to bridge the redesign timeline.
