LS3250A
MONOLITHIC DUAL
NPN TRANSISTOR
Linear Systems Log Conformance Monolithic Dual NPN
FEATURES
TIGHT MATCHING
The LS3250A is a monolithic pair of NPN transistors
mounted in a single P-DIP package. The monolithic
dual chip design reduces parasitics and is ideal for use
in tracking applications.

Notes:
1. Absolute Maximum ratings are limiting values above which serviceability may be impaired
2. The reverse base‐to‐emitter voltage must never exceed 6.2 volts; the reverse base‐to‐emitter current must never exceed 10µA.
