MAX4257EUA+ Overview


In order to protect the op amps, a 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) case is used. General Purpose-type instrumentation amplifiers are used in this application. Instrumentation amplifier is delivered in a Tube case. The number of terminations approaches 8. A total of 8 pins are attached to buffer op amp. I would like you to keep in mind that this buffer amplifier needs to be run at a voltage of 5V. It should be noted that this type of buffer amplifier is exactly what is known as a Operational Amplifier device. An 8-pin op amp ic is included in the package. As far as the input offset voltage is concerned, linear amplifier rates at 70μV. For this electrical component, the recommended mounting type is Surface Mount, which is the most common. It is important to note that this linear amplifier works well at a temperature of -40°C~85°C when it comes to operating temperatureA supply current of 420μA can be used to operate this linear amplifier. Maintain 116dB as the voltage gain. Op amp ic has 2 channels. As one of the many benefits of this buffer amplifier, it puts out Push-Pull, Rail-to-Rail signals, which is one of the many benefits it offers. The operating supply voltage of the buffer op amp is rated at 2.75V.
