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.
