Frequently Asked Questions
What is the difference between the LF412CN/NOPB and the LF412ACN?
The LF412CN/NOPB is the standard-grade version with a maximum input offset voltage of 3 mV and the /NOPB suffix indicating lead-free, RoHS-compliant packaging. The LF412ACN is a tighter-spec A-grade variant with 0.5 mV maximum offset voltage for higher precision applications.
What is the input bias current specification of the LF412CN/NOPB?
The LF412CN/NOPB has a maximum input bias current of 0.05 pA (50 fA) at 25°C, characteristic of JFET-input op-amps. This makes it suitable for high-impedance sensor interfaces like pH electrodes, piezoelectric transducers, and photodiodes where input leakage must be minimized.
Does the LF412CN/NOPB require external frequency compensation?
No, the LF412CN/NOPB is internally compensated and unity-gain stable. Unlike the LF412ACN which may require external compensation in some configurations, the standard LF412CN/NOPB can be used in any closed-loop gain configuration without additional compensation components.
What supply voltage does the LF412CN/NOPB operate on?
The LF412CN/NOPB operates from dual supply voltages from ±5 V to ±18 V (or single supply up to 36 V equivalent), compatible with standard ±12 V and ±15 V analog system power rails used in precision instruments and laboratory measurement equipment.
