TS488 - Pop-free 120 mW stereo headphone amplifier

Description

The TS488/9 is an enhancement of TS486/7 that eliminates pop and click noi

Features

  • Pop and click noise protection circuitry.
  • Operating range from VCC = 2.2 V to 5.5 V.
  • Standby mode active low (TS488) or high (TS489).
  • Output power:.
  • 120 mW at 5 V, into 16 Ω with 0.1% THD+N max (1 kHz).
  • 55 mW at 3.3 V, into 16 Ω with 0.1% THD+N max (1 kHz).
  • Low current consumption: 2.7 mA max at 5 V.
  • Ultra-low standby current consumption: 10 nA typical.
  • High signal-to-noise ratio.
  • High crosstalk immunity:.
