  • The A21SP16 is a differential class-D BTL power amplifier. It is able to drive up to 2.3 W into a 4 Ω load and 1.4 W into a 8 Ω load at 5 V. It achieves outstanding efficiency (88% typ.) compared to classical Class-AB 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) allows the reduction of current consumption to 10 nA typ.

    主要特性

    • Operating from VCC = 2.4 V to 5.5 V
    • Standby mode active low
    • Output power: 3 W into 4 Ω and 1.75 W into 8 Ω with 10% THD+N max and 5 V power supply
    • Output power: 2.3 W @ 5 V or 0.75 W @ 3 V into 4 Ω with 1% THD+N max
    • Output power: 1.4 W @ 5 V or 0.45 W @ 3 V into 8 Ω 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 & click noise
    • Thermal shutdown protection
    • Available in flip-chip 9 x 300 μm (Pb-free)
