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.

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. 2 Quintenz Hybridtechnik • www.quintenz.de • Fax 0049-89-759 25 45 copyright Quintenz Hybridtechnik 2004
