LF1650/LF2650/LF3650 quad JFET analog switch
general description
The LF1650/LF2650/LF3650 is a monolithic combination of bipolar and JFET technology producing the industry's first one chip quad FET switch_ A unique circuit technique is employed to maintain a constant RON over the analog
voltage range. The input is designed to operate from minimum TTL levels. and switch operation also ensures a break before make action.
features
Constant ON resistance for signals ±10V and 100 kHz
< tOFF tON. break before make action
Open switch isolation at 1.0 MHz
< 1.0 nA leakage in OFF state
-50 dB
TTL. DTL. RTL direct drive compatibility
Single disable pin turns all sWitches in package OFF
The LF1650/LF2650/LF3650 is designed to operate from ±15V supplies and swing a ±1 OV analog signal. The FET SWitches can be used wherever a dc to medium frequency analog signal needs to be controlled .
