  • 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 & 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.

    Key Features

    • PSRR: 63 dB typical at 217 Hz with 6 dB gain
    • Signal to noise ratio: 85 dB typical
    • Low pop & click noise
    • PWM base frequency: 280 kHz
    • Available in DFN8 3 x 3 mm package
    • Thermal shutdown protection
    • Low current consumption 2 mA at 3 V
    • Adjustable gain via external resistors
    • Operating from VCC = 2.4 V to 5.5 V
    • 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
    • Standby mode active low
    • Output power: 1.4 W at 5 V or 0.5 W at 3.0 V into 8 Ω with 1% THD+N maximum
    • Efficiency: 88% typical
    • Output power: 2.2 W at 5 V or 0.7 W at 3.0 V into 4 Ω with 1% THD+N maximum
