The LT1008 operational amplifier combines picoampere bias currents, microvolt offset voltage, low noise, and low power dissipation in a single device. It delivers up to 5 mA load current with high voltage gain and excellent common‑mode and power‑supply rejection ratios.
Typical applications include precision instrumentation, charge integrators, logarithmic amplifiers, light meters, low‑frequency active filters, thermocouple amplifiers and standard cell buffers. The device is offered in 8‑lead PDIP and SOIC packages and can operate from +2 V to +18 V supply voltages.

The LT1008 has a maximum input bias current of 100 pA at 25 °C.
The device can be powered from +2 V up to +18 V, and operation down to +1.2 V is possible with two Ni‑Cd batteries.
Its low‑frequency noise from 0.1 Hz to 10 Hz is specified as 0.5 µV peak‑to‑peak.
The LT1008 is offered in an 8‑lead PDIP (Narrow 0.300 in) and an 8‑lead plastic SOIC (Narrow 0.150 in) package.
