OPA4243EA/250 Product Details

OPA4243EA/250 Overview


Packaging for the buffer amplifier is in the form of a 14-TSSOP (0.173, 4.40mm Width) case. A General Purpose-type buffer amplifier is shown here. There is a Cut Tape (CT) case that is delivered with the instrumentation amplifiers. A total of 14 terminations have been reported in the past few weeks. Buffer amplifier has a total of 14 pins on it. I would like you to keep in mind that this buffer amplifier needs to be run at a voltage of 7.5V. In more specific terms, this linear amplifier can be categoriOperational Amplifiered as a Operational Amplifier-type device. An 14-pin op amp ic is included in the package. With regards to the offset voltage of the input, buffer amplifier is rated at 5mV. For this electrical component, the recommended mounting type is Surface Mount, which is the most common. The buffer amplifier functions well at -40°C~85°C as far as operating temperature is concerned. 104dB should be the voltage gain. There is an operating supply voltage rating of 4 for this operational amplifier, which is rated at the manufacturer. The operating supply voltage of the buffer op amp is rated at 18V. A TR-shaped amplifier is used to pack the buffer amps. A supply of 45μA or higher is recommended for use with this electronic part.
