It operates over a wide supply voltage range of 3V to 26V with low input offset voltage and low input bias current. AEC-Q100 qualified, it is suitable for automotive body electronics and industrial applications requiring reliable performance over the -40\u00b0C to +125\u00b0C temperature range.","working_principle":"The LM2904 consists of two independent high-gain internally compensated operational amplifiers. Each amplifier uses a differential input stage with active current mirror load, followed by a gain stage and a class AB output stage. The internal compensation capacitor ensures stability in unity-gain configurations without requiring external components. The output stage includes short-circuit protection. The input common-mode range extends to ground, enabling single-supply operation.","pin_description":"
