tracking configuration. A 100 kΩ, 20-turn potentiometer
is used for each trim. The potentiometer for gain trim is
connected between Pin 6 (V HIGH ) and Pin 8 (V LOW ) 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.

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

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
