TS4900
300mW at 3.3V SUPPLY AUDIO POWER AMPLIFIER
WITH STANDBY MODE ACTIVE HIGH
s OPERATING FROM VCC = 2.5V to 5.5V
s 0.7W OUTPUT POWER @ Vcc=5V, THD=1%,
f=1kHz, with an 8 Ω load
s 0.3W OUTPUT POWER @ Vcc=3.3V,
THD=1%, f=1kHz, with an 8 Ω 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 MiniSO8 & SO8
DESCRIPTION
The TS4900 is an audio power amplifier designed
to provide the best price to power ratio while pre-
serving high audio quality.
Available in MiniSO8 & SO8 package, it is capable
of delivering up to 0.7W of continuous RMS ouput
power into an 8Ω load @ 5V.
TS4900 is also exhibiting an outstanding 0.1%
distortion level (THD) from a 5V supply for a Pout
of 200mW RMS.
An externally controlled standby mode control re-
duces the supply current to less than 10nA. It also
includes an internal thermal shutdown protection.
The unity-gain stable amplifier can be configured
by external gain setting resistors.
APPLICATIONS
s Mobile Phones (Cellular / Cordless)
s PDAs
s Portable Audio Devices
