QA 452
High Voltage Amplifier
Rev 1.0
Shortform Datasheet
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
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.
Applications:
Sonar Driver, Piezo Driver, ATE and
others
Documented production to MIL-Standards
available on request. For similar products see:

2)
Testcondition: Input signal 1Vpp sinewave. Signal level has to be stabilized after appointed time.
3)
Testcondition: Zero input signal. 150µs after shutdown a 1Vpp/200kHz/50Ω 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 10kΩ. This allows to combine in- and output functionality in
one pin.
