TS4990

1.2 W audio power amplifier with active low standby mode

Features

■ Operating range from VCC = 2.2 V to 5.5 V

■ 1.2 W output power @ VCC = 5 V, THD = 1%,

F = 1 kHz, with 8

Ωload

■ Ultra-low consumption in standby mode (10 nA)

■ 62 dB PSRR at 217 Hz in grounded mode

■ Near-zero pop and click

■ Ultra-low distortion (0.1%)

■ Unity gain stable

■ Available in 9-bump flip-chip, miniSO-8 and

DFN8 packages

Applications

■ Mobile phones (cellular / cordless)

■ Laptop / notebook computers

■ PDAs

■ Portable audio devices

Description

The TS4990 is designed for demanding audio

applications such as mobile phones to reduce the

number of external components.

This audio power amplifier is capable of delivering

1.2 W of continuous RMS output power into an 8

Ω

load at 5 V.

An externally controlled standby mode reduces

the supply current to less than 10 nA. It also

includes an internal thermal shutdown protection.

The unity-gain stable amplifier can be configured

by external gain setting resistors.
