2MHz, Micropower Operational Amplifier
Features
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.
• Low Standby Power . . . . . . . . . . . . . . . As Low As 700nW
• Wide Supply Voltage Range . . . . . . . . . . ±0.75V to ±15V
• High Peak Output Current . . . . . . . . . . . . . . . 6.5mA (Min)
• Adjustable Quiescent Current
• Output Short Circuit Protection
Applications
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.

Application Information
Compensation Techniques
The CA3078A and CA3078 can be phase compensated with
one or two external components depending upon the closed
loop gain, power consumption, and speed desired. The
recommended compensation is a resistor in series with a
capacitor connected from Terminal 1 to Terminal 8. Values of
the resistor and capacitor required for compensation as a
function of closed loop gain are shown in Figures 25 and 26.
These curves represent the compensation necessary at
quiescent currents of 100µA and 20µA, respectively, for a
transient response with 10% overshoot. Figures 23 and 24
show the slew rates that can be obtained with the two different
compensation techniques. Higher speeds can be achieved
with input compensation, but this increases noise output.
Compensation can also be accomplished with a single
capacitor connected from Terminal 1 to Terminal 8, with speed
being sacrificed for simplicity. Table 1 gives an indication of
slew rates that can be obtained with various compensation
techniques at quiescent currents of 100µA and 20µA.
Single Supply Operation
The CA3078A and CA3078 can operate from a single supply
with a minimum total supply voltage of 1.5V. Figures 4 and 5
show the CA3078A or CA3078 in inverting and non-inverting
20dB amplifier configurations utilizing a 1.5V type “AA” cell
for a supply. The total consumption for either circuit is
approximately 675nW. The output voltage swing in this
configuration is 300mVP-P with a 20kΩ load.
