GATED

OSCILLATOR

The PA83 is a high voltage operational ampliﬁer designed

for output voltage swings up to ±±45V with a dual (±ꢀ supply or

290V with a single supply. Its input stage is protected against

transient and steady state overvoltages up to and including

the supply rails. High accuracy is achieved with a cascode

input circuit conﬁguration. All internal biasing is referenced

to a zener diode fed by a FET constant current source. As

a result, the PA83 features an unprecedented supply range

and excellent supply rejection. The output stage is biased in

the class A/B mode for linear operation. Internal phase com-

pensation assures stability at all gain settings without need

for external components. Fixed current limits protect these

ampliﬁers against shorts to common at supply voltages up to

±20V. For operation into inductive loads, two external ﬂyback

pulseprotectiondiodesarerecommended.However,aheatsink

may be necessary to maintain the proper case temperature

under normal operating conditions.

SIMPLE PIEZO ELECTRIC TRANSDUCER DRIVE

TYPICAL APPLICATION

While piezo electric transducers present a complex imped-

ance, they are often primarily capacitive at useful frequen-

cies. Due to this capacitance, the speed limitation for a given

transducer/ampliﬁer combination may well stem from limited

current drive rather than power bandwidth restrictions. With

its drive capability of 75mA, the PA83 can drive transducers

having up to 2nF of capacitance at 40kHz at maximum output

voltage. In the event the transducer may be subject to shock

or vibration, ﬂyback diodes, voltage clamps or other protection

networks must be added to protect the ampliﬁer from high

voltages which may be generated.

This hybrid circuit utilizes beryllia (BeOꢀ substrates, thick

(cermetꢀﬁlmresistors,ceramiccapacitorsandsiliconsemicon-

ductor chips to maximize reliability, minimize size and give top

performance. Ultrasonically bonded aluminum wires provide

reliable interconnections at all operating temperatures. The

8-pinTO-3 package is hermetically sealed and electrically iso-

lated.Theuseofcompressiblethermalisolationwashersand/or

improper mounting torque voids product warranty. Please see

NOTES:

The speciﬁcation of PA83A is identical to the speciﬁcation for PA83 in applicable column to the left.

±. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation to

achieve high MTTF.

2. The power supply voltage for all tests is the TYP rating, unless otherwise noted as a test condition.

3. Doubles for every ±0°C of temperature increase.

4. +V and –V_Sdenote the positive and negative supply rail respectively. Total V_Sis measured from +V_Sto –V_S.

5. Ra^Sting applies if the output current alternates between both output transistors at a rate faster than 60Hz.

6. Signal slew rates at pins 5 and 6 must be limited to less than ±V/ns to avoid damage. When faster waveforms are unavoidable,

resistors in series with those pins, limiting current to ±50mA will protect the ampliﬁer from damage.

The internal substrate contains beryllia (BeOꢀ. Do not break the seal. If accidentally broken, do not crush, machine, or

subject to temperatures in excess of 850°C to avoid generating toxic fumes.

2. Short circuits to ground are safe with dual supplies up to

±20V or single supplies up to ±20V.

3. Short circuits to the supply rails are safe with total supply

voltages up to ±20V, e.g. ±60V.

4. The output stage is protected against transient ﬂyback.

However, for protection against sustained, high energy

ﬂyback, external fast-recovery diodes should be used.

SAFE OPERATING AREA (SOA)

The bipolar output stage of this high voltage ampliﬁer has

two distinct limitations.

INDUCTIVE LOADS

Two external diodes as shown in Figure ±, are required

to protect these ampliﬁers against ﬂyback (kickbackꢀ pulses

exceeding the supply voltages of the ampliﬁer when driving

inductiveloads. Forcomponentselection,theseexternaldiodes

must be very quick, such as ultra fast recovery diodes with

no more than 200 nanoseconds of reverse recovery time. Be

sure the diode voltage rating is greater than the total of both

supplies. The diode will turn on to divert the ﬂyback energy

into the supply rails thus protecting the output transistors from

destruction due to reverse bias.

±. The internal current limit, which limits maximum available

output current.
