(Optional)
The frequency response of the 1-6H001 can be
adjusted by use of an external compensation capacitor
from pin 8 to common as show in Figure 1. The open­

various values of capacitance. The 1-6H001 is stable at
any gain level without the use of compensation,
provided that stray wiring capacitance and/or load
capacitance are not excessive, and that moderate
values of feedback resistance are used (R_FB ~ 10 kn).
A load capacitance of SOpF is desirable in all feed

back configurations.
Stability
Because the 1-6H001 is an extremely fast amplifier
with high gain, stray wiring capacitance and
inductance in power supply leads can cause circuit
oscillation. This can be prevented by proper circuit
layout (all leads or patterns as short as possible) and
properly bypassing the power supply line to common
V+
at points close to the amplifier. In addition, it is
recommended the the load be bypassed by a SOpF
capacitor. See Figure 1.

Offset Voltage and Adjustment
Although the offset voltage of these amplifiers is only a
few millivolts, it may in some cases be desirable to
null this offset. This is done by use of a 100kn
potentiometer as shown in Figure 2.
Test Circuit-Dynamic Response
The test circuit of Figure 3 is used for measurement of
slew rate, settling time, rise time and overshoot. Both
rise time and overshoot are measured for a small
output signal (V _{O UT} = ± 100mV). Slew rate and
settling time are measured by a 10V, peak-to-peak,
square wave.
