OUTPUT RAIL TO RAIL 1W AUDIO POWER AMPLIFIER
WITH STANDBY MODE
s OPERATING FROM VCC = 2.5V to 5.5V
s 1W RAIL TO RAIL OUTPUT POWER @
Vcc=5V, THD=1%, f=1kHz, with 8Ω Load
s ULTRA LOW CONSUMPTION IN STANDBY
MODE (10nA)
s 75dB PSRR @ 217Hz from 5V to 2.6V
s ULTRA LOW POP & CLICK
s ULTRA LOW DISTORTION (0.1%)
s UNITY GAIN STABLE
s AVAILABLE IN SO8, MiniSO8 & DFN8 3x3mm
DESCRIPTION
The TS4871 is an Audio Power Amplifier capable
of delivering 1W of continuous RMS Ouput Power
into 8Ω load @ 5V.
This Audio Amplifier is exhibiting 0.1% distortion
level (THD) from a 5V supply for a Pout = 250mW
RMS. An external standby mode control reduces
the supply current to less than 10nA. An internal
thermal shutdown protection is also provided.
The TS4871 has been designed for high quality
audio applications such as mobile phones and to
minimize the number of external components.
The unity-gain stable amplifier can be configured
by external gain setting resistors.
APPLICATIONS
s Mobile Phones (Cellular / Cordless)
s Laptop / Notebook Computers
s PDAs
s Portable Audio Devices
