The A21SP16 is a differential class-D BTL power amplifier. It is able to drive up to 2.3 W into a 4 O load and 1.4 W into a 8 O 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.

  • Operating from VCC = 2.4 V to 5.5 V
  • Standby mode active low
  • Output power: 3 W into 4 O and 1.75 W into 8 O 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 O with 1% THD+N max
  • Output power: 1.4 W @ 5 V or 0.45 W @ 3 V into 8 O 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)
