The IL062 is high speed J-FET input dual operational amplifier.
This J-FET input operational amplifier incorporates well matched, high
voltage J-FET and bipolar transistors in a monolithic integrated circuit.
The devices feature high slew rates, low input bias and offset currents,
and low offset voltage temperature coefficient.
Operation Very low power consumption: 200
Wide common-mode (up to V
CC
+
) and differential voltage ranges
Low input bias and offset currents
Output short-circuit protection
High input impedance J-FET input stage
Internal frequency compensation
Latch up free operation
High slew rate: 3.5V/s

Notes
.
1.
All voltage values, except differential voltage, are with respect to the zero reference level (ground) of the supply
voltages where the zero reference level is the midpoint between V
CC
+
and V
CC
-
.
2.
Differential voltages are at the non-inverting input terminal with respect to the inverting input terminal.
3.
The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 volts, whichever is
less.
4.
The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to
ensure that the dissipation rating is not exceeded.

* Input bias currents of a FET- input operational amplifier are normal junction reverse currents, which are
temperature sensitive.
Pulse techniques must be used that will maintain the junction temperature as closes to the ambient temperature as
possible.
