Discrete transistors can be used to increase output drive to ±70V at ±10A as shown above. With proper thermal
design, the IC will provide safe-area protection for the external transistors. Voltage gain is about thirty.
OPERATIONAL POWER SUPPLY
Note: Supply voltages for the LM318s are ±15V
External current limit can be provided for a power op amp as shown above. The positive and negative current
limits can be set precisely and independently. Fast response is assured by D₁ and D₂. Adjustment range can be
set down to zero with potentiometers R₃ and R₇. Alternately, the limit can be programmed from a voltage
supplied to R₂ and R₆. This is the set up required for an operational power supply or voltage-programmable
power source.
