5 | Reference | Output reference input. Normally connected to common |
6 | Output | Amplifier output pin |
7 | Power (+Vs) | Positive supply terminal |
8 | Gain (+Rg) | Non - Inverting Gain Terminal connected to resistor to set gain value |
How to use AD623 IC
The AD623 only requires a resistor to sets its gain value and hence can be easily set up. A very basic commonly used circuit for AD623 is shown below.
