The LT1012IS8 is an internally compensated universal precision operational amplifier which can be used in practically all precision applications. The LT1012IS8 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 LT1012IS8 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 LT1012IS8 eliminates the necessity of the time consuming error analysis procedure of precision system design in many applications; the LT1012IS8 can be stocked as the universal internally compensated precision op amp.
