BA4558 Overview

In the package, you will find a 8-DIP (0.300, 7.62mm)-case to contain the op amp ic. General Purpose-type instrumentation amplifiers are used in this application. Linear amplifier is delivered in a Tube case. It is estimated that there will be at least 8 terminations this year. In this case, there are 8 pins on the board. I would like to remind you that this buffer op amp should be powered by an 15V battery. A type of Operational Amplifier op amp ic can be identified by the fact that this is a type of Operational Amplifier device. A total of 8 pins are present on the instrumentation amplifier. Op amp rates 500μV as input offset voltage. It is recommended that this electronic component be mounted using the Through Hole mounting type. The buffer amplifier functions well at -40°C~85°C as far as operating temperature is concerned. Using a supply current of 3mA , this buffer op amp will be able to operate. The voltage gain should stay at 100dB. There are 2 circuits on this op amp. The operating supply voltage of instrumentation amplifier is rated 15V voltage.
