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.
