NOTES: * The specification of PA82J is identical to the specification for PA81J in applicable column to the left.
1. The power supply voltage for all specifications is the TYP rating unless noted as a test condition.
2. +VS and –VS denote the positive and negative supply rail respectively. Total VS is measured from +VS to –VS.
3. Rating applies if the output current alternates between both output transistors at a rate faster than 60Hz.
4. On the PA81J and PA82J, signal slew rates at pins 5 and 6 must be limited to less than 1V/ns to avoid damage. When faster
waveforms are unavoidable, resistors in series with those pins, limiting current to 150mA will protect the amplifier from damage.
CAUTION
The internal substrate contains beryllia (BeO). 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.
