LS404 is a high performance quad operational amplifier with frequency and phase compensation built into the chip
The LS404 is a high‑performance quad operational amplifier offered in DIP‑14 and micro‑package (SO) formats. It features single or split‑supply operation, low power consumption, short‑circuit protection, low distortion, low noise, high gain‑bandwidth product, and excellent channel separation, making it suitable for professional and telecom applications such as active filters.
The datasheet details absolute maximum ratings, electrical characteristics, pin connections, mechanical dimensions, and example filter designs. It also lists temperature ranges for the LS404C, LS404I, and LS404M variants, and provides typical performance figures such as supply current, input bias current, offset voltage, slew rate, and gain‑bandwidth product.
