GENERAL DESCRIPTION
FEATURES
There are 4 different gain settings at BTL mode -6dB, 10dB, 15.6dB and 21.6dB, changed by setting GAIN0, GAIN1 pins. At SE mode, the gain is fixed 4.1dB. The AA4006 can amplify square waveform beep input signal from BEEP_IN pin and its' output can always reach BTL terminal, masking all other audio inputs regardless of whether the chip is in shutdown, SE or BTL mode. The AA4006 is available in TSSOP-24 (EDP) package .● Output Power, THD+N=10%: 110mW at SE mode for 32Ω Headphone 220mW at SE mode for 16Ω Headphone 1.5W at BTL mode for 8Ω Speaker 2.3W at BTL mode for 4Ω Speaker 2.7W at BTL mode for 3Ω Speaker
