Bare Die Product Detail: J111

N-Channel Switch / Chopper:
Low noise Single N-Channel JFET switch. The J111 N-channel JFET is optimised for low noise high performance switching. The part is particularly suitable for use in low noise audio amplifiers.

Featuring low leakage and fast switching time this device is a direct replacement for Interfet, Intersil, Motorola, National / Fairchild, Philips, Vishay / Siliconix J111 or SST111 & Toshiba 2SJ111.

Features:

Short Sample-&-Hold Aperture Time
Low insertion loss
Low noise

Applications:

Analog Switches
Commutators
Choppers
