LF442ACN Product Details

LF442ACN Overview


In the package, you will find a 8-DIP (0.300, 7.62mm)-case to contain the op amp ic. An op amp of this type is a J-FET-type. In the case of Tube cases, linear amplifier will be delivered. It is estimated that there will be at least 8 terminations this year. It consists of a total of 8 pins in total. As a reminder, this buffer op amp should be powered by 20V battery and that the battery should be inserted in the amplifier. It should be noted that this op amp is a type of Operational Amplifier device. There are 8 pins on this chip. The input offset voltage is 1mV. Through Hole is the recommended mounting type of operational amplifiers. According to the manufacturer, this buffer op amp works well at 0°C~70°C , which is a good operating temperature. Using an 300μA supply current, this operational amplifier ics can be operated. Op amp is a member of the 106.02dB's 106.02dB family. There is an operating supply voltage rating of 2 for this operational amplifier, which is rated at the manufacturer. The operating supply voltage of the buffer op amp is rated at 22V. The BI-FET II? indicates the series number of the op amp.
