Frequently Asked Questions
What is the input bias current of the LF412ACN?
The LF412ACN has a maximum input bias current (IIB) of 0.2 pA at 25°C, which is characteristic of JFET-input op-amps, making it suitable for high-impedance source applications like electrochemical sensors and photodiodes where even femtoamp leakage matters.
What is the input offset voltage specification of the LF412ACN?
The LF412ACN (A-grade) has a maximum input offset voltage of 0.5 mV, improved from the standard LF412CN's 1 mV max, making the ACN grade suitable for precision DC amplifier designs requiring minimal zero-point error without external trimming.
What is the CMRR of the LF412ACN?
The LF412ACN provides a minimum common-mode rejection ratio (CMRR) of 80 dB and typically 100 dB, enabling effective rejection of ground noise and supply hum in sensitive analog measurement chains and instrumentation amplifier front-ends.
Is the LF412ACN suitable as a drop-in replacement for the TL072 or NE5532?
The LF412ACN is pin-compatible with the 8-pin dual op-amp configuration used by TL072 and similar JFET-input op-amps, offering lower input bias current and better offset voltage than the TL072, making it a direct upgrade in many precision analog designs.
