LS120

MONOLITHIC DUAL

NPN TRANSISTOR

LS120 Features:

Tight matching

Low Output Capacitance

The LS120 is a monolithic pair of NPN transistors

mounted in a single P-DIP package. The monolithic

dual chip design reduces parasitics and gives better

performance while ensuring extremely tight matching.

The LS120 is a direct replacement for discontinued

Intersil IT120.

The 8 Pin P-DIP provides ease of manufacturing, and

the symmetrical pinout prevents improper orientation.

(See Packaging Information).

Linear Systems replaces discontinued Intersil IT120

Available Packages:

LS120 in P-DIP

LS120 available as bare die
