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.
