Dual Supplies

National Semiconductor LM2900 and

LM3900, Respectively

description

These devices consist of four independent, high-

gain frequency-compensated Norton operational

amplifiers that were designed specifically to

operate from a single supply over a wide range of

voltages. Operation from split supplies is also

possible. The low supply current drain is

essentially independent of the magnitude of the

supply voltage. These devices provide wide band-

width and large output voltage swing.

The LM2900 is characterized for operation from

–40

°C to 85°C, and the LM3900 is characterized

for operation from 0

°C to 70°C.
