NOTE
• For Ei, use a voltage source of low noise and good stability. Noise in Ei is
multiplied by the amplification degree of the unit and appears in the unit's
output. Thus, output ripple noise may not meet the unit's specifications.

Input offset voltage
The relationship between the input and
output voltages of the unit is represented by
input offset voltage, as shown in Fig. 4-7.
This ensures a 0 V output even in the
presence of residual resistance in the
potentiometer or some wiring resistance
during voltage control using an external
resistor. When linearity is required to
program the output voltage, adjust the input
offset voltage using the V.
