MOTOROLA ANALOG IC DEVICE DATA
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.
