LM308A

LM308A Precision Operational Amplifier The LM308A operational amplifier provides high input impedance, low input offset and temperature drift, and low noise. These characteristics are made possible by use of a special Super Beta processing technology. This amplifier is particularly useful for applications where high accuracy and low drift performance are essential. In addition high speed performance may be improved by employing feedforward compensation techniques to maximize slew rate without compromising other performance criteria. The LM308A offers extremely low input offset voltage and drift specifications allowing usage in even the most critical applications without external offset nulling.
