DESCRIPTION
The TLV320DAC32 is a low power stereo audio DAC with and integrated power amplifier designed to drive stereo headphones or speakers. This device also has a pair of analog inputs which allow routing of external signals to the output amplifiers. The playback path includes a mix/mux capability from the stereo DAC and analog inputs, through programmable volume controls, to the headphone outputs. Extensive register-based power control is included, enabling stereo 96-k Hz playback as low as 20m W from a 3.3-V analog supply, making it ideal for portable battery-powered audio and telephony applications.
The TLV320DAC32 contains four high-power output drivers. These drivers are capable of driving a variety of load configurations, including up to four channels of single-ended 16-Ω headphones using ac-coupling capacitors, or stereo 16-Ω headphones in a cap-less output configuration. In addition, pairs of drivers can be used to drive 8-Ω speakers in a BTL configuration at 500 m W per channel.
The stereo audio DAC supports sampling rates from 8-k Hz to 96-k Hz and includes...
