NOTES 
1 . Absolute maximum ratings are limiting values above which LS4118A serviceability may be impaired.  
2.  Due to symmetrical geometry, these units may be operated with source and drain leads interchanged 
3. This parameter is measured during a 2ms interval 100ms after power is applied.  (Not a JEDEC condition.)

LS4118A Benefits:
Insignificant Signal Loss / Error Voltage
with High-Impedance Source
Low Power Consumption (Battery)
Maximum Signal Output, Low Noise
High Sensitivity to Low-Level Signals
The LS4118A provides ultra-high input impedance. The
device is specified with a 1-pA limit and typically
operates at 0.2 pA. The part is ideal for use as a high-
impedance sensitive front-end amplifier.
LS4118A Applications:
High-Impedance Transducer
Smoke Detector Input
Infrared Detector Amplifier
Precision Test Equipment
