What is LM318PE4 used for?
The LM318PE4 is used in high-speed analog signal processing circuits such as comparators, active filters, and sample-and-hold amplifiers where fast slew rate is essential for accurate waveform reproduction. Its 70 dB CMRR makes it suitable for differential signal amplification in instrumentation and data acquisition front ends. Legacy industrial equipment, educational electronics labs, and prototype development boards also use this device due to its through-hole PDIP package.

Frequently Asked Questions
How does the high slew rate of LM318PE4 benefit comparator and waveform-shaping circuits?
The LM318PE4 has a slew rate of approximately 70 V/µs, allowing it to respond to fast input transitions within microseconds. In comparator or schmitt-trigger circuits this enables clean, fast output transitions that reduce propagation delay distortion when switching at high signal frequencies above 1 MHz.
What CMRR does the LM318PE4 guarantee, and how much common-mode noise does it reject?
The LM318PE4 guarantees a minimum 70 dB common-mode rejection ratio, which means a 1 V common-mode signal is reduced to less than 316 µV at the output. The typical CMRR is 100 dB, further improving noise rejection in differential measurement systems with ground-loop or power-supply interference.
Can LM318PE4 interface directly with high-impedance piezoelectric or photodiode sensors?
The LM318PE4 maximum input bias current of 0.75 µA and offset current of 0.2 µA allow connection to moderately high-impedance sources. For a 1 MΩ source impedance, the 0.75 µA bias current introduces up to 750 mV offset, so a compensation network or lower source impedance is recommended for precision piezo or photodiode transimpedance applications.
When maintaining a legacy PCB that uses LM318PE4, what modern through-hole op-amp offers improved offset with a compatible footprint?
The OPA2134PA or LM358P in an 8-pin PDIP package offer pin-compatible through-hole alternatives with lower input offset voltage, typically below 500 µV versus the LM318PE4's 10 mV maximum. This reduces DC error in precision amplifier stages without requiring any PCB modification.
