Quad op-amp in 14-SOIC — commercial temperature, obsolete status
It integrates four independent amplifiers with a 1 MHz gain bandwidth product and draws 1.5 mA total supply current, making it a fit for multi-channel signal conditioning in temperature-controlled indoor equipment such as bench instruments, appliance control boards, and office automation.
Supply range and input characteristics
The LM324M operates from a single supply spanning 3 V to 32 V, or dual supplies up to ±16 V, which lets it interface directly with 5 V logic rails and 24 V industrial sensors without an intermediate regulator. Input bias current is 45 nA typical, and input offset voltage is 2 mV typical — adequate for non-critical DC-coupled stages like level shifting, active filters below 100 kHz, and transducer amplification where precision below 1 mV is not required.
