TS4962M 3 W filter-free class D audio power amplifier Datasheet - production data Related products See TS2007 for further gain settings e.g. 6 or 12 dB See TS2012 for stereo settings Applications Portable gaming consoles VR headsets Smart phones Tablets Description The TS4962M is a differential Class-D BTL power Features amplifier. It is able to drive up to 2.3 W into a 4 load and 1.4 W into a 8 load at 5 V. It achieves Operating from V = 2.4 V to 5.5 V CC outstanding efficiency (88% typ.) compared to Standby mode active low classical Class-AB audio amps. Output power: 3 W into 4 and 1.75 W into 8 The gain of the device can be controlled via two with 10% THD+N max. and 5 V power supply external gain-setting resistors. Pop and click Output power: 2.3 W 5 V or 0.75 W 3.0 V reduction circuitry provides low on/off switch into 4 with 1% THD+N max. noise while allowing the device to start within 5 ms. A standby function (active low) allows the Output power: 1.4 W 5 V or 0.45 W 3.0 V reduction of current consumption to 10 nA typ. into 8 with 1% THD+N max. Adjustable gain via external resistors Low current consumption 2 mA 3 V Efficiency: 88% typ. Signal to noise ratio: 85 dB typ. PSRR: 63 dB typ. 217 Hz with 6 dB gain PWM base frequency: 250 kHz Low pop and click noise Available in Flip Chip 9 x 300 m (Pb-free) March 2020 DocID11703 Rev 7 1/41 This is information on a product in full production. www.st.comContents TS4962M Contents 1 Block diagram and pinout 3 2 Application component information 4 3 Absolute maximum ratings . 5 4 Electrical characteristics . 6 5 Electrical characteristic curves . 17 6 Application information . 28 6.1 Differential configuration principle 28 6.2 Gain in typical application schematic 28 6.3 Common-mode feedback loop limitations 29 6.4 Low frequency response . 29 6.5 Decoupling of the circuit 30 6.6 Wake-up time (t ) . 30 WU 6.7 Shutdown time (t ) . 30 STBY 6.8 Consumption in shutdown mode . 30 6.9 Single-ended input configuration . 31 6.10 Output filter considerations 32 6.11 Different examples with summed inputs 33 7 Evaluation board . 35 8 Package information 37 8.1 9-bump Flip Chip package information . 37 9 Ordering information . 39 10 Revision history . 40 2/41 DocID11703 Rev 7
