AD588  
Data Sheet  
39k  
Figure 5 shows gain and balance trims in a +5 V and −5 V  
tracking configuration. A 100 kΩ, 20-turn potentiometer  
is used for each trim. The potentiometer for gain trim is  
connected between Pin 6 (VHIGH) and Pin 8 (VLOW) with the  
wiper connected to Pin 5 (GAIN ADJ). The potentiometer is  
adjusted to produce exactly 10 V between Pin 1 and Pin 15, the  
amplifier outputs. The balance potentiometer, also connected  
between Pin 6 and Pin 8 with the wiper to Pin 12 (BAL ADJ), is  
then adjusted to center the span from +5 V to −5 V.

Trimming in other configurations works in exactly the same  
manner. When producing +10 V and +5 V, GAIN ADJ is used  
to trim +10 V and BAL ADJ is used to trim +5 V. In the −10 V  
and −5 V configuration, GAIN ADJ is again used to trim the  
magnitude of the span, −10 V, while BAL ADJ is used to trim  
the center tap, −5 V.

Trimming the AD588 introduces no additional errors over  
temperature, so precision potentiometers are not required. For  
single-output voltage ranges, or in cases when balance adjust is  
not required, Pin 12 should be connected to Pin 11. If gain  
adjust is not required, Pin 5 should be left floating.

Figure 5. +5 V and −5 V Outputs  
In single output configurations, GAIN ADJ is used to trim  
outputs utilizing the full span (+10 V or −10 V), while BAL ADJ  
is used to trim outputs using half the span (+5 V or −5 V).

Input impedance on both the GAIN ADJ and BAL ADJ pins is  
approximately 150 kΩ. The GAIN ADJ trim network effectively  
attenuates the 10 V across the trim potentiometer by a factor of  
about 1500 to provide a trim range of −3.5 mV to +7.5 mV with  
a resolution of approximately 550 μV/turn (20-turn potentiome-  
ter). The BAL ADJ trim network attenuates the trim voltage by  
a factor of about 1400, providing a trim range of 4.5 mV with  
resolution of 450 ꢀV/turn.
