Guaranteed Operation at

±1.2V Supplies

The LT

precision operational amplifier which can be used in

practically all precision applications. The LT1012

combines picoampere bias currents (which are

maintained over the full –55

°C to 125°C temperature

range), microvolt offset voltage (and low drift with time

and temperature), low voltage and current noise, and

low power dissipation. The LT1012 achieves precision

operation on two Ni-Cad batteries with 1mW of power

dissipation. Extremely high common mode and

power supply rejection ratios, practically unmeasurable

warm-up drift, and the ability to deliver 5mA load current

with a voltage gain of one million round out the LT1012’s

superb precision specifications.

The all around excellence of the LT1012 eliminates the

necessity of the time consuming error analysis procedure

of precision system design in many applications; the

LT1012 can be stocked as the universal internally

compensated precision op amp.
