AD8644ARZ Overview


Packaged in a 14-SOIC (0.154, 3.90mm Width) case, the buffer op amp is ready to use. A General Purpose-type buffer amplifier is shown here. In the case of Tube cases, linear amplifier will be delivered. It is estimated that there will be at least 14 terminations this year. Buffer amplifier has a total of 14 pins on it. Please take in mind that this instrumentation amplifier should be run at 18V. This particular linear amplifier is a type of Operational Amplifier device, to be precise. The op amp ic has an array of 14 pins on it. In terms of input offset voltage, operational amplifier rates 2.5mV. This electronic component is recommended to be mounted using the mounting type Surface Mount. In terms of operating temperature, this instrumentation amplifier performs well at a temperature of about -20°C~85°C . A supply current of 4.4mA can be used to operate this linear amplifier. Keeping the voltage gain at 103.52dB is the best course of action. There are a total of 4 channels available on the op amps. One of its many advantages is that buffer op amp outputs Rail-to-Rail signals. The operating supply voltage of instrumentation amplifier is rated 15V voltage. Buffer amplifier has a quiescent current of 1.1mA.
