At 0.5 V/µs, the full output swing of 20 Vpp (on a 30 V supply) is limited to roughly 8 kHz before slew-rate distortion sets in. For lower swings the usable frequency scales proportionally — a 2 Vpp signal can swing cleanly up to about 80 kHz. This makes the LM324DG4 a fit for sensor filtering, DC level shifting, and low-speed control loops, not for audio line drivers or high-speed ADC front ends. ## 20 nA input bias — DC accuracy trade-off The 20 nA input bias current (typical) and 3 mV input offset voltage mean the DC accuracy is adequate for 1% resistor networks and 8-bit ADC interfaces, but the bias current will cause a voltage drop across high-impedance sources. If your feedback network uses 1 MΩ resistors, expect an additional 20 mV of offset — budget for it or scale the resistor values down. ## Last-buy status — plan your final order Procurement should commit the remaining BOM quantity now, because once the last-buy window closes, the only channel will be independent surplus. ## Pin-compatible across the LM324 family The LM324DG4 uses the standard quad op-amp pinout common to all LM324 devices in a 14-pin SOIC. Any other LM324 variant in the same 14-SOIC footprint — from TI or from a second-source manufacturer — will drop into the same board layout without a PCB change. The differences are in temperature grade, supply current, and lifecycle status, not pin assignment.","metaTitle":"LM324DG4 General-Purpose Op-Amp, 1.2 MHz, 0.5 V/µs, Last-Buy","metaDescription":"Texas Instruments LM324DG4 quad general-purpose op-amp in 14-SOIC. 1.2 MHz GBP, 0.5 V/µs slew rate, 3–30 V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Slew Rate":"0.5V/µs","Output Type":"-","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Last Time Buy","lifecycle_stage":"eol_hot","Current - Supply":"1.4mA (x4 Channels)","Number of Circuits":"4","Base Product Number":"LM324","Current - Input Bias":"20 nA","Operating Temperature":"0°C ~ 70°C (TA)","Gain Bandwidth Product":"1.2 MHz","Voltage - Input Offset":"3 mV","Supplier Device Package":"14-SOIC","Current - Output / Channel":"40 mA","Voltage - Supply Span (Max)":"30 V","Voltage - Supply Span (Min)":"3 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/82fa63e30c4c5cc784748c213bc64c16.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM324DG4/alternatives.json"},"ai":{"faq":[{"question":"Is LM324DG4 obsolete or last time buy?","answer":"Yes, the LM324DG4 is listed as Last Buy.
