–
95-dBA Signal-to-Noise Ratio  
16/20/24/32-Bit Data  
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-kHz playback as low as 20mW from a  
3.3-V analog supply, making it ideal for portable  
battery-powered audio and telephony applications.  
Supports Rates From 8 kHz to 96 kHz

Stereo Fully Differential or Single-Ended  
Headphone Drivers  
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 mW per channel.

Generation  
I2C Control Bus  
Audio Serial Data Bus Supports I2S,  
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.  
•
•
Left/Right-Justified, DSP, and TDM Modes  
•
•
Extensive Modular Power Control  
The serial control bus uses the I2C protocol, while the  
serial audio data bus is programmable for I2S,  
left/right-justified, DSP, or TDM modes. A highly  
programmable PLL is included for flexible clock  
generation and support for all standard audio rates  
from a wide range of available MCLKs, varying from  
512-kHz to 50-MHz, with special attention paid to the  
most popular cases of 12-MHz, 13-MHz, 16-MHz,  
19.2-MHz, and 19.68-MHz system clocks.  
Internal Selectable LDO Allows Operation

נ
5 mm 32-QFN  
The TLV320DAC32 operates from analog supplies of  
2.7 V – 3.6 V, a digital core supply of 1.525 V – 1.95  
V, and a digital I/O supply of 1.1 V – 3.6 V. An  
internal LDO regulator allows the device to internally  
generate the lower voltage power supply needed for  
digital core logic, thereby allowing full operation from  
a single 3.3-V supply voltage.  
The TLV320DAC32 is a software-compatible subset  
of the existing TLV320AIC32 and TLV320AIC33  
audio codecs, allowing simple transition from a  
system with record and playback to a system with  
playback only.
