The LT1008 is a precision operational amplifier from National Semiconductor that is capable of extremely low bias currents, microvolt offset voltage, low voltage and current noise, and low power dissipation. It also has extremely high common mode and power supply rejection ratios, and can deliver 5mA of load current with high voltage gain.
The LT1008 is a universal precision operational amplifier designed for applications that require ultra‑low bias current, low offset voltage and low noise. It offers picoampere bias currents over the full –55 °C to 125 °C temperature range, microvolt‑level offset, high common‑mode and power‑supply rejection, and can deliver up to 5 mA load current with high voltage gain.
The device is offered in several 8‑lead packages (PDIP, plastic SOIC and metal can) and operates from +2 V to +18 V (down to +1.2 V in special cases). Detailed electrical characteristics, typical performance graphs, and application notes are provided for precision instrumentation, charge integrators, low‑frequency filters, thermocouple amplifiers and more.
