1 / 44 page  This is information on a product in full production. March 2020 DocID10968 Rev 9 1/44 TS4962 2.8 W filter-free mono class D audio power amplifier Datasheet - production data Features • Operating from V CC = 2.4 V to 5.5 V • Standby mode active low • Output power: 2.8 W into 4 Ω and 1.7 W into 8 Ω with 10% THD+N maximum and 5 V power supply • Output power: 2.2 W at 5 V or 0.7 W at 3.0 V into 4 Ω with 1% THD+N maximum • Output power: 1.4 W at 5 V or 0.5 W at 3.0 V into 8 Ω with 1% THD+N maximum • Adjustable gain via external resistors • Low current consumption 2 mA at 3 V • Efficiency: 88% typical • Signal to noise ratio: 85 dB typical • PSRR: 63 dB typical at 217 Hz with 6 dB gain • PWM base frequency: 280 kHz • Low pop and click noise • Available in DFN8 3 x 3 mm package Applications • Cellular phones • PDAs • Notebook PCs Description The TS4962 is a differential class-D BTL power amplifier. It can drive up to 2.2 W into a 4 Ω load and 1.4 W into an 8 Ω load at 5 V. It achieves outstanding efficiency (88% typ.) compared to standard AB-class audio amps. The gain of the device can be controlled via two external gain setting resistors. Pop and click reduction circuitry provides low on/off switch noise while allowing the device to start within 5 ms. A standby function (active low) enables the current consumption to be reduced to 10 nA typical. www.st.com |
