Dual/Quad, Low Power CMOS Operational  
Amplifiers  
Features  
• Wide Operating Voltage Range . . . . . . . . . . . ±1V to ±8V  
12  
The ICL761X/762X/764X series is a family of monolithic  
CMOS operational amplifiers. These devices provide the  
designer with high performance operation at low supply  
voltages and selectable quiescent currents. They are an  
ideal design tool when ultra low input current and low power  
dissipation are desired.  
• High Input Impedance . . . . . . . . . . . . . . . . . . . . . . .10  
Ω
• Input Current Lower Than BIFETs . . . . . . . . . . . 1pA (Typ)  
• Output Voltage Swing . . . . . . . . . . . . . . . . . . . . V+ and V-  
• Available as Duals and Quads (Refer to ICL7611 for Singles)  
• Low Power Replacement for Many Standard Op Amps  
The basic amplifier will operate at supply voltages ranging  
from ±1V to ±8V, and may be operated from a single Lithium  
cell. The output swing ranges to within a few millivolts of the  
supply voltages.  
Applications  
• Portable Instruments  
• Telephone Headsets  
• Hearing Aid/Microphone Amplifiers  
• Meter Amplifiers  
The quiescent supply current of these amplifiers is set to 3  
different ranges at the factory. Both amps of the dual  
ICL7621 are set to an I of 100µA, while each amplifier of  
Q
• Medical Instruments  
• High Impedance Buffers  
the quad ICL7641 and ICL7642 are set to an I of 1mA and  
Q
10µA respectively. This results in power consumption as low  
as 20µW per amplifier.  
Pinouts

Of particular significance is the extremely low (1pA) input

current, input noise current of 0.01pA/√Hz, and 10 Ω input  
impedance. These features optimize performance in very  
high source impedance applications.

AC performance is excellent, with a slew rate of 1.6V/µs, and  
unity gain bandwidth of 1MHz at I = 1mA.

Because of the low power dissipation, junction temperature  
rise and drift are quite low. Applications utilizing these  
features may include stable instruments, extended life  
designs, or high density packages.
