2.2  Pins of Operational Amplifier 
The OPAMP uses the OPAMP_P pin and the OPAMP_N pin as the analog input pins of the 
operational amplifier, and uses the OPAMP_O pin as the analog output pin of the operational 
amplifier. 
When GS [5] is set to "1B" and GS [4:0] is set to "00000B", the OPAMP will work as a 
standalone open loop operational amplifier. 
When GS [5] is set to "0B", the OPAMP will work as a non-inverting closed loop operational 
amplifier. It provides six different closed loop gain settings through the software.
