Dual, Low Power CMOS Operational  
Amplifiers  
Features  
• Wide Operating Voltage Range . . . . . . . . . . . ±1V to ±8V  
12  
The ICL761X/762X 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 (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  
100µA at the factory. This results in power consumption as  
low as 200µW per amplifier.  
• Medical Instruments  
• High Impedance Buffers  
Of particular significance is the extremely low (1pA) input  
12  
current, input noise current of 0.01pA/√Hz, and 10 Ω input  
impedance. These features optimize performance in very  
high source impedance applications.

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.

*Pb-free PDIPs can be used for through hole wave solder processing only.  
They are not intended for use in Reflow solder processing applications.  
NOTES:  
1. Add “-T” suffix for tape and reel. Please refer to TB347 for details on reel  
specifications.  
2. These Intersil Pb-free plastic packaged products employ special Pb-  
free material sets, molding compounds/die attach materials, and 100%  
matte tin plate plus anneal (e3 termination finish, which is RoHS  
compliant and compatible with both SnPb and Pb-free soldering  
operations). Intersil Pb-free products are MSL classified at Pb-free  
peak reflow temperatures that meet or exceed the Pb-free  
requirements of IPC/JEDEC J STD-020.  
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
