1.4MHz, Low Power CMOS Operational  
Amplifiers  
Features  
• Wide Operating Voltage Range . . . . . . . . . . . ±1V to ±8V  
12  
The ICL761X series is a family of CMOS operational  
amplifiers. These devices provide the designer with high  
performance operation at low supply voltages and selectable  
quiescent currents, and are an ideal design tool when ultra  
low input current and low power dissipation are desired.  
• High Input Impedance . . . . . . . . . . . . . . . . . . . . . . 10  
Ω
• Programmable Power Consumption . . . . . Low as 20μW  
• Input Current Lower Than BIFETs . . . . . . . . . . . 1pA (Typ)  
• Output Voltage Swing . . . . . . . . . . . . . . . . . . . V+ and V-  
The basic amplifier will operate at supply voltages ranging  
from ±1V to ±8V, and may be operated from a single  
Lithium cell.  
• Input Common Mode Voltage Range Greater Than Supply  
Rails (ICL7612)  
• Pb-Free Plus Anneal Available (RoHS Compliant)  
A unique quiescent current programming pin allows setting  
of standby current to 1mA, 100μA, or 10μA, with no external  
components. This results in power consumption as low as  
20μW. The output swing ranges to within a few millivolts of  
the supply voltages.  
Applications  
• Portable Instruments  
Telephone Headsets  
• Hearing Aid/Microphone Amplifiers  
• Meter Amplifiers  
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.  
• Medical Instruments  
• High Impedance Buffers  
The inputs are internally protected. Outputs are fully  
protected against short circuits to ground or to either supply.  
AC performance is excellent, with a slew rate of 1.6V/μs, and  
unity gain bandwidth of 1MHz at I = 1mA.  
Q
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.
