LV4912GP
Overview
The LV4912GP is analog input type digital power amplifier with 2W
× 1 channel. By using an original feed back
technology, it improves sound quality through it is class-D power amplifier and the LC filter in the output stage can be
deleted as application.
Features
Enabling output LC filter-less.
Class-D amplifier system of the output BTL type.
Improve the sound quality by the use of original feedback technology.
Realized high efficiency class-D amplifier.
Reduce the pop sound at ON/OFF state by the use of soft mute function.
Full complement of built-in protection circuits : over current protection, thermal protection, and low power supply
voltage protection circuits.
Internal oscillation frequency : 280kHz
Functions
Output power : 2W(VD = 5V, RL = 4Ω, THD + N = 10%)
THD + N
: 0.4% (VD = 5V, RL = 4Ω, fin = 1kHz, PO = 1W, Filter : AES17)
Noise
: 70
μVrms (Filter : DIN AUDIO)
