Features

General

  • Wide supply voltage range 2.5 V - 5.5 V
  • Two digital inputs (I2S and PCM/IOM2 formats, 1.8 V and 3.3 V tolerant) which are less sensitive to external RF fields
  • Internal Phase-Locked Loop (PLL) requiring no system clock
  • High efficiency of 92% and low power consumption
  • Closed loop amplifier resulting in excellent audio performance:
    • PSRR = -76 dB
    • S/N = -95 dB (A-weighted)
    • THD+N = 0.015% at 100 mWRMS
  • High-power capability:
    • 2.7 WRMS in 4 W Ω BTL at 5 V
    • 1.6 WRMS in 8 W Ω BTL at 5 V
  • Protections including diagnostic via I2C:
    • I2S and PCM/IOM2 input protections
