LN3992 Description

The LN3992 is a 1.7W mono fully-differential amplifier designed to drive a speaker with at least 8Ω impedance while consuming only 20 mm2 total printed-circuit board (PCB) area in most applications. The device operates from 2.5V to 5.5V, drawing only 4mA of quiescent supply current. The LN3992 is ideal for PDA/smart phone applications due.
