Productos<\/h2>\n

El LM324AN es un amplificador operacional cu\u00e1druple de prop\u00f3sito general est\u00e1ndar del sector de Texas Instruments en un encapsulado PDIP-14 con orificio pasante. La versi\u00f3n A ofrece una tensi\u00f3n de offset de entrada m\u00e1xima mejorada de 3 mV (frente a los 7 mV del LM324N). Funciona con una alimentaci\u00f3n \u00fanica de 3 V a 32 V o doble de +\/-1,5 V a +\/-16 V con s\u00f3lo 700 \u03bcA de corriente de reposo total. El rango de modo com\u00fan de entrada incluye tierra, y la salida puede oscilar a tierra sin resistencias pull-down, lo que lo hace excepcionalmente vers\u00e1til para dise\u00f1os de alimentaci\u00f3n \u00fanica.<\/p>\n

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":"
