Hardware
In order to utilize the full drive capabilities of the
ELH0033 it should be mounted with a heatsink
particularly for extended temperature operation
The case is isolated from the circuit and may be
connected to system chassis
Operation within an Op Amp Loop
Both devices may be used as a current booster or
isolation buffer within a closed loop with op
amps such as the ELH0032 and HA2500 and
HA2600 series An isolation resistor of 47X
should be used between the op amp output and
the input of ELH0033 The wide bandwidth and
high slew rates of the ELH0033 assure that the
loop has the characteristics of the op amp and
that additional rolloff is not required
IMPORTANT
Power supply bypassing is necessary to prevent
oscillation with the ELH0033 in all circuits Low
inductance ceramic disc capacitors with the
shortest practical lead lengths must be connected
from each supply lead (within
to
of the
device package) to a ground plane Capacitors
should be one or two 0 1mF in parallel adding a
4 7
mF
solid tantalum capacitor will help in trou-
blesome instances
