J175
P-CHANNEL JFET
Linear Systems replaces discontinued Siliconix J175
The J175 is a single P-Channel JFET switch
This p-channel analog switch is designed to provide low
on-resistance and fast switching. When used in
combination with the complimentary J/SST111 n-
channel family, the J175 simplifies series-shunt
switching applications
.
Low Error Voltage
High-Speed Analog Circuit Performance
Negligible “Off-Error,” Excellent Accuracy
Good Frequency Response
Eliminates Additional Buffering
