LME49740NA/NOPB Overview
In order to protect the op amps, a 14-DIP (0.300, 7.62mm) case is used. Audio-type instrumentation amplifiers are used in this application. Upon delivery, op amp ic is packaged in a Tube case. It is estimated that there will be 14 terminations in the next few months. In this case, there are 14 pins on the board. As a reminder, this buffer op amp should be powered by 15V battery and that the battery should be inserted in the amplifier. In order to be more specific, this instrumentation amplifier is one of the types of Operational Amplifier devices. An 14-pin op amp ic is included in the package. In terms of the input offset voltage, instrumentation amplifier rates at 100μV. For this electrical component, Through Hole is the recommended mounting type. The buffer amplifier functions well at -40°C~85°C as far as operating temperature is concerned. As long as the supply current of the chip does not exceed 18.5mA, this op amp ic can operate. 140dB should remain the voltage gain. Depending on the chip's operating supply voltage, op amp ic has a rated voltage of 4. The operating supply voltage of the buffer op amp is rated at 17V. A RAIL-shaped amplifier is used to pack the buffer amps.
