Customer specific details:
-
Different hermetically sealed
metal packages available
-
Quiescent current
-
Internal compensation
-
Temperature alarm/shutdown
-
The amplifiers requires an
additional +5V supply for the
control of the shutdown feature.
This supply voltage can be
changed to other values, like
3.3V or 12V.
Features:
High Voltage, High Speed Amplifier
JFET Input
High Gain Bandwith Product: 20MHz
Rugged MOSFET output stage
Shutdown w. high impedance output
and reduced current consumption
(down to 1mA)
Two shutdown modes possible
Overtemp Protection
Overtemp Alarm Output
Customer tuned
Hermetically sealed and isolated metal
packages
Applications:
Sonar Driver, Piezo Driver, ATE and
others

Testcondition: Input signal 1Vpp sinewave. Signal level has to be stabilized after appointed time.
3)
Testcondition: Zero input signal. 150
s after shutdown a 1Vpp/200kHz/50
sinewave source will be
connected to the output. The signal at the output must not be distorted.
Shutdown Control:
The shutdown is controlled by a 5V-CMOS-level signal. Overtemperature shutdown
overrides normal shutdown. If overtemperature shutdown is active, the SD pin is
pulled to +5V by internal 10k
. This allows to combine in- and output functionality in
one pin.
