Output
Current
The
peak
output
current
is
150
mA
per
channel
in
the
grounded
load
configuration
or
75
mA
per
channel
in
the
floating
load
configuration.
The
maximum
RMS
current
is
106
mA
in
the
grounded
configuration
and
53
mA
in
the
floating
load
configuration.
The
maximum
simultaneous
output
current
from
all
channels
is
1.5
A.

Power
Bandwidth
The
nominal
slew
‐
rate
of
the
PD32
in
the
grounded
load
configuration
is
19
V/us.
Therefore,
the
unloaded
maximum
frequency
sine
‐
wave
is
19
10
.
That
is,
the
power
bandwidth
for
a
120
Vp
‐
p
sine
‐
wave
is
50
kHz.
In
the
floating
load
configuration,
the
slew
‐
rate
is
doubled
to
38
V/us,
therefore,
the
power
bandwidth
for
a
240
Vp
‐
p
sine
‐
wave
is
50
kHz
With
a
capacitive
load,
the
power
bandwidth
is
limited
by
the
output
current.
The
maximum
frequency
sine
wave
is
where
is
the
peak
current
limit,
is
the
peak
‐
to
‐
peak
output
voltage,
and
is
the
effective
load
capacitance.
The
power
bandwidth
versus
load
capacitance
is
listed
below.
