LOW POWER STEREO AUDIO DAC FOR PORTABLE AUDIO/TELEPHONY Stereo Audio DAC 95-dBA Signal-to-Noise Ratio The TLV320DAC32isa low power stereo audio DAC
with and integrated power amplifier designedto drive
– 16/20/24/32-Bit Data stereo headphonesor speakers. This device also has
– Supports Rates From8 kHzto96 kHz a pairof analog inputs which allow routingof external
3D/Bass/Treble/EQ/De-emphasis Effects signalsto the output amplifiers. The playback path
includesa mix/mux capability from the stereo DAC•
Two Audio Input Pins and analog inputs, through programmable volume
– Allows Analog Bypass Path controls, to the headphone outputs. Extensive•
Four Audio Output Drivers register-based power controlis included, enabling
stereo 96-kHz playback as low as 20mW froma
– Stereo 8-Ω, 500-mW/Channel Speaker Drive3.3-V analog supply, makingit ideal for portable
Capability battery-powered audio and telephony applications.
– Stereo Fully Differentialor Single-EndedThe TLV320DAC32 contains four high-power output
Headphone Driversdrivers. These drivers are capableof drivinga variety•
Low Power: 18-mW Stereo 48-kHz Playback of load configurations, including upto four channels
With 3.3-V Analog Supply of single-ended 16-Ω headphones using ac-coupling•
Programmable Input/Output Analog Gains capacitors,or stereo 16-Ω headphonesina cap-less
output configuration.In addition, pairsof drivers can•
Programmable Microphone Bias Level usedto drive 8-Ω speakersina BTL configuration•
Headphone Jack Detection at 500 mW per channel.•
Programmable PLL for Flexible Clock The stereo audio DAC supports sampling rates from
Generation 8-kHzto 96-kHz and includes programmable digital•
I2C Control Bus filtering in the DAC path for 3D, bass, treble,•
Audio Serial Data Bus SupportsI2S, midrange effects, speaker equalization, and
Left/Right-Justified, DSP, and TDM Modes de-emphasisfor 32-kHz, 44.1-kHz, and 48-kHz rates.
Extensive Modular Power Control The serial control bus uses the I2C protocol, while the
serial audio data bus is programmable for I2S,•
Internal Selectable LDO Allows Operationleft/right-justified, DSP, or TDM modes.A highly
From Single 3.3-V Supplyprogrammable PLL is included for flexible clock•
Power Supplies: generation and support for all standard audio rates
– Analog: 2.7 V–3.6V. froma wide rangeof available MCLKs, varying from
512-kHzto 50-MHz, with special attention paidto the
– Digital Core: 1.525 V–1.95Vmost popular casesof 12-MHz, 13-MHz, 16-MHz,
– Digital I/O: 1.1 V–3.6V 19.2-MHz, and 19.68-MHz system clocks.•
Package:5נ5 mm 32-QFNThe TLV320DAC32 operates from analog suppliesof
2.7V– 3.6V,a digital core supplyof 1.525V– 1.95 anda digital I/O supplyof 1.1V– 3.6 V. An
internal LDO regulator allows the deviceto internally
generate the lower voltage power supply needed for
digital core logic, thereby allowing full operation from single 3.3-V supply voltage.
The TLV320DAC32isa software-compatible subset the existing TLV320AIC32 and TLV320AIC33
audio codecs, allowing simple transition froma
