11. As a final design step, Ci must be selected to pass the lower passband frequency corner of 8 Hz for this

example.

A larger value may be used and a 0.01

μF ceramic capacitor

in parallel with Ci will maintain high frequency gain accuracy.

GENERAL PRECAUTIONS

The LM359 is designed primarily for single supply operation but split supplies may be used if the negative supply

voltage is well regulated as the amplifiers have no negative supply rejection.

The total device power dissipation must always be kept in mind when selecting an operating supply voltage, the

programming current, ISET, and the load resistance, particularly when DC coupling the output to a succeeding

stage. To prevent damaging the current mirror input diode, the mirror current should always be limited to 10 mA,

or less, which is important if the input is susceptible to high voltage transients. The voltage at any of the inputs

must not be forced more negative than

−0.7V without limiting the current to 10 mA.

The supply voltage must never be reversed to the device; however, plugging the device into a socket backwards

would then connect the positive supply voltage to the pin that has no internal connection (pin 5) which may

prevent inadvertent device failure.
