CA3078, CA3078A

2MHz, Micropower Operational Amplifier

The CA3078 and CA3078A are high gain monolithic

operational amplifiers which can deliver milliamperes of

current yet only consume microwatts of standby power. Their

operating points are externally adjustable and frequency

compensation may be accomplished with one external

capacitor. The CA3078 and CA3078A provide the designer

with the opportunity to tailor the frequency response and

improve the slew rate without sacrificing power. Operation

with a single 1.5V battery is a practical reality with these

devices.

The CA3078A is a premium device having a supply voltage

range of V

± = 0.75V to V± = 15V. The CA3078 has the same

lower supply voltage limit but the upper limit is V+ = +6V and

V- = -6V.

Features

• Low Standby Power . . . . . . . . . . . . . . . As Low As 700nW
