QUAD OPERATIONAL AMPLIFIERS
FAIRCHILD LINEAR INTEGRATED CIRCUITS
GENERAL DESCRIPTION - The .uA 148 series is a true quad .uA741. It consists of four
independent, high gain, internally compensated, low power operational amplifiers which
have been designed to provide functional characteristics identical to those of the familiar
.uA741 operational amplifier. In addition, the total supply current for all four amplifiers is
comparable to the supply current of a single .uA741 type op amp.
Other features include input offset currents and input bias current which are much less
than those of a standard .uA741. Also, excellent isolation between amplifiers has been
achieved by independently biasing each amplifier and using layout techniques which mini·
mize thermal coupling. The .uA 149 series has the same features as the.uA 148 except that
it is decompensated to give a gain bandwidth product of 4 MHz typical at a gain greater
than 5.

NOTES:
1. Any of the amplifier outputs can be shorted to ground indefinitely; however, more than one should not be simultaneously shorted as the maximum junction
temperature will be exceeded.
2. The maximum power dissipation for these devices must be derated at elevated temperatures and is dictated byTJ (MAX). 8JA. and the ambient temperature,
TA. The maximum available power dissipalion al any lemperalure is PD = (TJ (MAX) - TA)/9JA or Ihe 25°C PD (MAX), whichever is less.
3. ~A148, 248, 348 are capable of driving 100 pF capacilive load. ~A149, 249, 349 are capable of driving 50 pF capacilive load.
