EmStat3-MUX16 for OEM 

 

EmStat3-MUX16 for OEM 

3.3

 

MUX16 configurations 

 

 

 
Possible sensor configurations are: 

1

 

Sensor arrays with up to 16 working and 16 combined reference/counter electrodes  

2

 

Sensor arrays with up to 16 working electrodes all sharing a reference and a counter electrode  

3

 

Sensor arrays with up to 16 working electrodes sharing a combined reference/counter electrode  

In these configurations the sensors or electrodes can be multiplexed, leaving the not-selected sensors at 
open circuit when jumper J3 in not placed. 
J3 is placed when the potential has to be applied to all working electrodes simultaneously 
 
 
Jumpers: 
J1: RE to CE  
 

Connects the CE and RE leads when placed. Place J1 when only a combined CE and RE is 

 

applied. An alternative is to leave J1 open and always connect both the CE and RE leads to your 

 

RE/CE electrode 

J2: active 
 

Jumper is always placed. 

J3: (unselected WE) to AGND  
 

Keeps all WE’s at applied potential when placed. If not placed only the selected WE has an 

 

applied potential leaving not-selected WE’s at open circuit. 

J4: (unselected WE) to standby potential 
 

See section 3.3 

  
Jumper settings for the available configurations: 
 

Conf. 1:  Sensor array with up to 16 working and 16 combined reference/counter electrodes: 

 

Jumpers to be placed: J1 and J2 
When J3 is also placed, the potential is applied to all working electrodes continuously. 
Use pin 1, 3, 5 …. to 31 to connect all combined RE/CE electrodes.
