These devices are built to offer minimum offset voltage and differential

thermal response, and they can also be used for switching and

amplifying applications in -0.40V to -8.0V (+/-0.20V to +/-4.0V)

powered systems where low input bias current, low input capacitance,

and fast switching speed are desired. These devices, exhibiting well

controlled turn-off and sub-threshold characteristics, operate the

same as standard enhancement mode P-Channel MOSFETs.

However, the precision of the Gate Threshold Voltage enable two

key additional characteristics, or operating features. First, the

operating current level varies exponentially with gate bias voltage at

GENERAL DESCRIPTION (cont.)

or below the Gate Threshold Voltage (subthreshold region). Second,

the circuit can be biased and operated in the subthreshold region

with nA of bias current and nW of power dissipation.

For most general applications, connect the V+ pin to the most

positive voltage and the V- and IC (internally-connected) pins to the

most negative voltage in the system. All other pins must have

voltages within these voltage limits at all times. Standard ESD

protection facilities and procedures for static sensitive devices are

required when handling these devices.
