2.6W Mono Audio Amplifier with Shutdown Mode

Features

General Description

Depop Circuitry Integrated

The G1445 is a mono audio power amplifier in

MSOP-8 (FD), TDFN3X3-8 and WLCSP2X4-8 pack-

age. It can drive 2W continuous RMS power into 4Ω

load in Bridge- Tied Load (BTL) mode at 5V supply

voltage. Its THD is smaller than 1% under the above

operation condition. For the low current consumption

applications, the SHDN mode is supported to disable

the G1445 when it is idle. The current consumption

can be further reduced to below 1µA.

2.7V to 5.5V Operation

Output Power at 10% THD+N, VDD=5V

--2.6W (typical) into a 3Ω Load

Output Power at 1% THD+N, VDD=5V

--2W (typical) into a 4Ω Load

--1.3W (typical) into a 8Ω Load

Mono Bridge-Tied Load (BTL)

Shutdown Control Available

MSOP-8 (FD) , TDFN3X3-8 Package &

WLCSP2X4-8 Available

Giving the SHUTDOWN pin low level will drive the

G1445 entering the shutdown.
