AD8644ARUZ Overview

In order to protect the op amps, a 14-TSSOP (0.173, 4.40mm Width) case is used. An op amp of this type is a General Purpose-type. A Tube case is used to deliver the buffer op amp. In recent months, the number of terminations has approached 14. In this case, there are 14 pins on the board. Please take in mind that this instrumentation amplifier should be run at 18V. A type of Operational Amplifier op amp ic can be identified by the fact that this is a type of Operational Amplifier device. The op amp ic has an array of 14 pins on it. Regarding input offset voltage, op amp rates 2.5mV. It is recommended that this electronic component be mounted using the Surface Mount mounting type. The buffer amplifier functions well at -20°C~85°C  as far as operating temperature is concerned. A supply current of 4.4mA can be used to operate this linear amplifier. It is a member of the 103.52dB's 103.52dB family. Op amp ic has 4 channels. One of the advantages of this op amp is that it outputs Rail-to-Rail signals, which is one of its many advantages. The operating supply voltage of the buffer op amp is rated at 15V. As a result, linear amplifier's quiescent current is 1.1mA.
