4 Channels 70mA per Channel 80nA 75 dB Instrumentational OP Amps 0.0005μA 15V 5V~18V AD8644 14 Pins 14-SOIC (0.154, 3.90mm Width)
AD8644ARZ Overview
In order to protect the op amps, a 14-SOIC (0.154, 3.90mm Width) case is used. There are two types of operational amplifiers in this circuit. In the case of Tube cases, linear amplifier will be delivered. In recent months, the number of terminations has approached 14. It consists of a total of 14 pins in total. It would be helpful if you could remember that this op amp ic should be powered by an 18V battery. It has 14 pins that make up the linear amplifier. 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. It is recommended that this op amp ic be operated at a temperature no higher than -20°C~85°C for optimal performance. In order for this instrumentation amplifier to operate, the supply current needs to be between 4.4mA and 10 . 103.52dB should remain the voltage gain. Buffer op amp is equipped with 4 channels on the device. As one of the many benefits of this buffer amplifier, it puts out 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 15V. There is an 1.1mA quiescent current in linear amplifier.
