LT1008IN8

精密放大器 LT1008 - Picoamp Input Current, Microvolt Offset, Low Noise Op Amp

DESCRIPTION

The LT®1008 is a universal precision operational amplifier that 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.
