DESCRIPTION
The TLV320AIC33 is a low power stereo audio
codec with stereo headphone amplifier, as well as
multiple inputs and outputs programmable in
single-ended or fully differential configurations.
Extensive register- based power control is included,
enabling stereo 48-kHz DAC playback as low as 14
mW from a 3.3-V analog supply, making it ideal for
portable battery-powered audio and telephony
applications.
The record path of the TLV320AIC33 contains
integrated microphone bias, digitally controlled stereo
microphone preamplifier, and automatic gain control
(AGC), with mix/mux capability among the multiple
analog inputs. The playback path includes mix/mux
capability from the stereo DAC and selected inputs,
through programmable volume controls, to the
various outputs.
The TLV320AIC33 contains four high-power output
drivers as well as three fully differential output
drivers. The high-power output 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 capacitorless output configuration.
In addition, pairs of drivers can be used to drive 8-Ω
speakers in a BTL configuration at 500 mW per
channel.
The stereo audio DAC supports sampling rates from
8 kHz to 96 kHz and includes programmable digital
filtering in the DAC path for 3D, bass, treble,
midrange effects, speaker equalization, and
de-emphasis for 32-kHz, 44.1-kHz, and 48-kHz
rates. The stereo audio ADC supports sampling rates
from 8 kHz to 96 kHz and is preceded by
programmable gain amplifiers providing up to
+59.5-dB analog gain for low-level microphone
inputs.
