HJ148 is a monolithic quad operational amplifier made using silicon epitaxial planar technology, essentially integrating four independent LM741 operational amplifiers into a single chip. Therefore, each operational amplifier possesses various characteristics of the LM741, such as high gain, internal compensation, low power consumption, etc. Moreover, the HJ148 has a lower quiescent current. The total quiescent current of the four operational amplifiers is equivalent to that of one LM741, and its input bias current and input offset current are also much lower than those of the LM741. Due to advanced isolation technology and reasonable layout design, there is good electrical matching between the four operational amplifiers, with channel isolation exceeding 120dB. The HJ148 is suitable for electronic systems that require multiple operational amplifiers with consistent performance to ensure matching and high assembly density requirements. The HJ148 uses an H14-02 black ceramic surface mount package, further reducing size and improving reliability, making it more suitable for military electronic equipment. The pin arrangement and performance parameters of the HJ148 are the same as those of the LM148 and MC4741, allowing for mutual substitution.
