LT1012A/LT1012 Picoamp Input Current, Microvolt Offset, Low Noise Op Amp DESCRIPTIO The LT ®1012 is an internally pensated universal precision operational amplifier which can be used in practically all precision applications. The LT1012 bines 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 1m W of power dissipation. Extremely high mon mode and power supply rejection ratios, practically unmeasurable warm-up drift, and the ability to deliver 5m A 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 pensated precision op amp. , LTC and LT are registered trademarks of Linear Technology Corporation.
