TS4902ID-TS4902IDT
300MW AT 3.3V SUPPLY AUDIO POWER AMPLIFIER WITH STANDBY MODE ACTIVE LOW
0.3W OUTPUT POWER @ Vcc=3.3V, THD=1%, f=1kHz, with an 8Ω load ULTRA LOW CONSUMPTION IN STANDBY
MODE (10nA)
77dB PSRR @ 217Hz from 5V to 2.2V ULTRA LOW POP & CLICK ULTRA LOW DISTORTION (0.1%) UNITY GAIN STABLE� AVAILABLE IN MiniSO8 & SO8
DESCRIPTIONThe TS4902 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.
TS4902 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 reduces
the supply current to less than 10nA. It also in-
cludes an internal thermal shutdown protection.
The unity-gain stable amplifier can be configured
by external gain setting resistors.

ABSOLUTE MAXIMUM RATINGS
OPERATING CONDITIONS All voltages values are measured with respect to the ground pin. The magnitude of input signal must never exceed VCC + 0.3V / GND - 0.3V Device is protected in case of over temperature by a thermal shutdown active @ 150°C. Exceeding the power derating curves during a long period, will cause abnormal operation. This thermal resistance can be reduced with a suitable PCB layout (see Power Derating Curves)

ELECTRICAL CHARACTERISTICSVCC = +5V, GND = 0V, Tamb = 25°C (unless otherwise specified)
VCC = +3.3V, GND = 0V, Tamb = 25°C (unless otherwise specified)3)
Standby mode is actived when Vstdby is tied to GND Dynamic measurements - 20*log(rms(Vout)/rms(Vripple)). Vripple is the surimposed sinus signal to Vcc @ f = 217Hz Standby mode is actived when Vstdby is tied to GND Dynamic measurements - 20*log(rms(Vout)/rms(Vripple)). Vripple is the surimposed sinus signal to Vcc @ f = 217Hz
3. All electrical values are made by correlation between 2.6V and 5V measurements

ELECTRICAL CHARACTERISTICSVCC = 2.6V, GND = 0V, Tamb = 25°C (unless otherwise specified)
REMARKS
1. All measurements, except PSRR measurements, are made with a supply bypass capacitor Cs = 100μF.
2. The standby response time is about 1μs. Standby mode is actived when Vstdby is tied to GND Dynamic measurements - 20*log(rms(Vout)/rms(Vripple)). Vripple is the surimposed sinus signal to Vcc @ f = 217Hz
