The A-version provides improved 3 mV max input offset voltage (vs. 7 mV for the LM324N). It operates from a single 3 V to 32 V or dual +\/-1.5 V to +\/-16 V supply with only […]<\/p>\n","protected":false},"author":2,"featured_media":2243,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[13,20],"tags":[],"chip_brand":[138],"class_list":["post-2105","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-integrated-circuits-ics","category-interface-ics","chip_brand-ti"],"acf":{"brief_explanation":"Quad 30V 1.2MHz general-purpose op-amp, PDIP-14, single 3-32V or dual +\/-1.5-+\/-16V supply, 3mV max Vos, 700uA Iq, 0.5V\/us slew rate, 0-70C.","date_code":"","package_case":"PDIP-14 (19.31 x 6.35 x 5.08mm)","in_stock":6506,"datasheet":"https:\/\/www.ti.com\/product\/LM324","price":"$0.145 @ 1000+","product_introduction":"The LM324AN is TI industry-standard quad general-purpose operational amplifier in PDIP-14 package. The A-version offers improved 3mV max input offset voltage (vs 7mV for LM324N). It operates from single 3V-32V or dual +\/-1.5V to +\/-16V supplies with only 700uA quiescent current. Input common-mode range includes ground, and output swings to ground without pull-down resistors. 1.2MHz GBW and unity-gain stability make it versatile for DC gain, active filters, and signal conditioning.","working_principle":"The LM324A uses bipolar technology with a PNP differential input pair. Input bias current flows out of the IC (~45nA typ), allowing common-mode range to extend 0.3V below ground. The output stage is push-pull but has asymmetric drive: 40mA source vs 20mA sink. Internal frequency compensation ensures unity-gain stability without external components. Quiescent current is nearly independent of supply voltage, ideal for battery operation. Differential input voltage withstands up to supply rails without clamping diodes.","pin_description":"
