AD8644AR Product Details

AD8644AR Overview


It is packaged in an 14-SOIC (0.154, 3.90mm Width)-case that protects the operational amplifiers from damage. An op amp of this type is a General Purpose-type. As far as the packaging is concerned, buffer op amp is delivered in a Tube case. It is estimated that there will be at least 14 terminations this year. A total of 14 pins are attached to buffer op amp. As a reminder, this buffer op amp should be powered by 18V battery and that the battery should be inserted in the amplifier. A type of Operational Amplifier op amp ic can be identified by the fact that this is a type of Operational Amplifier device. This electronic part is recommended for mounting type Surface Mount. In terms of operating temperature, this instrumentation amplifier is well suited to a temperature range of -20°C~85°C. This op amp ic has 4 circuits. One of its many advantages is that buffer op amp outputs Rail-to-Rail signals. For optimal performance, this electrical part should be connected to a supply with a current of 800μA.
