LF444CM Overview


There is a 14-SOIC (0.154, 3.90mm Width) case in which the instrumentation amplifier is packaged. There are two types of operational amplifiers in this circuit. As far as the packaging is concerned, buffer op amp is delivered in a Tube case. In recent months, the number of terminations has approached 14. The pins on this board total to 14 in total. It is important to remember that this op amp should be operated at a voltage of 15V volts. To be specific, this instrumentation amplifier is a type of Operational Amplifier. An 14-pin op amp ic is included in the package. Op amp ic rates 10mV for input offset voltage. This electronic component is recommended to be mounted using the mounting type Surface Mount. It is recommended that this op amp ic be operated at a temperature no higher than 0°C~70°C for optimal performance. As long as the supply current of the chip does not exceed 600μA, this op amp ic can operate. Keeping the voltage gain at 100dB is the best course of action. Buffer op amp is equipped with 4 channels on the device. The operating supply voltage of instrumentation amplifier is rated 18V voltage. The BI-FET? indicates the series number of the op amp.
