Specifications 

Number of channels 

2-16 

Multiplexer use:   

 

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

 

 

Sensor arrays with up to 16 eight working and the same 
combined reference/counter electrode  

 

 

Sensor arrays with up to 16 working electrodes, each with its 
own combined reference/counter electrode  

On resistance 

WE channels: 2 ohm typical (see note)   

Leakage current 

10 pA typical at 25 ºC (see note) 

Charge injection 

20 pC typical (see note) 

Connections: 

Shielded flat cable, with stripped end leads or 
by means of the MUX16 Terminal Block (in shielded housing) 

 

 

16 WE’s 

 

 

CE 

 

 

RE 

 

 

RE and CE can be connected together and in this case 
connected to up to 16 combined CE/RE electrode 

 

 

analog ground for shielding 

Dimensions of PCB 

76 x 74 mm

 

 
 
 
Note: for very low current applications, the PCB can be populated with components with lower leakage 
(10 pA typical) and lower charge injection (1 pC) properties. These components can be used for 
measurements with currents always below approx. 100 uA.
