The LT1008 is a universal precision operational amplifier which can be used in practically all precision applications. The LT1008 combines for the first time 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. Extremely high common-mode and power supply rejection ratios, and the ability to deliver 5mA load current with high voltage gain round out the LT1008's superb precision specifications.

The all around excellence of the LT1008 eliminates the necessity of the time consuming error analysis procedure of precision system design in many applications; the LT1008 can be stocked as the universal precision op amp.

The LT1008 is externally compensated with a single capacitor for additional flexibility in shaping the frequency response of the amplifier. It plugs into and upgrades all standard LM108A/308A applications. For an internally compensated version with even lower offset voltage but otherwise similar performance see the LT1012.
