QA452 Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – High Voltage Amplifier

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
Applications:
Sonar Driver, Piezo Driver, ATE and
others
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.
Documented production to MIL-Standards
available on request. For similar products see:
