Note 1:  The SW2-1 is turned ON (1) with suppressed zero 

range, while it is turned OFF (0) with elevated zero 
range.

Note 2:  With suppressed zero range, weight of bit (mV) is 

added by turning ON (1) each one of the SW2-8 to 
SW2-2, while with  elevated zero range, it is added by 
turning OFF (0) the same.   
For example, 20mV bias (zero suppression) is nearly 
obtained by turning on SW2-1 (positive), SW2-4 and 
SW2-8 (19mV + 1.2mV = 20.2mV).

Note 3:  When the test pin reads a positive voltage, turning one 

bit ON (1) decreases the bias. 
When the test pin reads a negative voltage, turning 
one bit OFF (0) increases the bias.

Note 1:  Gain indicates the multiplying factor adjustable with 

SW3.

Note 2: Gain is calculated by using the following equation:

Gain =

2000 (mV)

20 (V100% – V0%)

 

 

 

Where   V100% = input span

 

 

 

 

    V0% = input zero

 

Add an weight of bits according to the gain value.

 

 For example, with 0 – 4.2mV input, the calculated 
gain, 23.8, is rounded to either 23 or 24.

 

Then turn off (0) SW3-3 and SW3-7.  

 

Alternately, turn off (0) SW3-3, SW3-7 and SW3-8.
