FEATURES  
DESCRIPTION

•
Hardware Control  
The PCM510x devices are a family of monolithic  
CMOS integrated circuits that include a stereo  
digital-to-analog converter and additional support  
circuitry in a small TSSOP package. The PCM510x  
uses the latest generation of TI’s advanced segment  
DAC architecture to achieve excellent dynamic  
performance and improved tolerance to clock jitter.

SNR: 112/106/100dB (Typical)  
Dynamic Range: 112/106/100dB (Typical)  
THD+N: - 93/-92/90dB @ - 1dBfs (Typical)  
Full Scale Output: 2.1VRMS (Ground Center)  
No DC Blocking Capacitors Required  
Market leading low out of band noise.  
The PCM510x devices are simpler hardware  
controlled 2VRMS DACs, with filter select, PLL and  
auto-mute functions.  
•
•
Digital Filter Latency & Performance Select  
Normal 8× Oversampling Digital Filter:  
The PCM510x provides 2.1VRMS ground centered  
outputs, allowing designers to eliminate DC blocking  
capacitors on the output, as well as external muting  
circuits traditionally associated with single supply line  
drivers.

Stopband Attenuation: –60dB  
Passband Ripple: ±0.02dB  
•
Low Latency 8× Oversampling Digital Filter:  
–
–
Stopband Attenuation: –52dB  
Passband Ripple: ±0.0001dB  
The integrated line driver surpasses all other  
charge-pump based line drivers by supporting loads  
down to 1kΩ.  
•
•
Sampling Frequency: 8kHz To 384kHz  
System Clock Multiples (fSCK): 64, 128, 192,  
256, 384, 512, 768, 1024, 1152, 1536, 2048, 3072  
Accepts 16-, 24-, And 32-Bit Audio Data  
PCM Data Formats: I2s, Left-Justified  
Intelligent Muting System, Soft Up/Down Ramp  
& Analog Mute For 120dB Mute SNR With  
Popless Operation.  
Integrated Power On Reset  
Integrated Negative Charge Pump  
Integrated High-Performance Audio PLL With  
BCK Reference To Generate SCK Internally  
Automatic Power-Save Mode When LRCK And  
BCK Are Deactivated.  
By supporting loads down to 1kΩ, the PCM510x can  
essentially drive up to 10 products in parallel. (LCD  
TV, DVDR, AV Receivers etc).  
•
•
•
The integrated PLL on the device removes the  
requirement for a system clock (commonly known as  
master clock). This allows a 3-wire I2S connection,  
along with reduced system EMI.  
•
•
•
Intelligent clock error and PowerSense under voltage  
protection utilizes a two level mute system for  
pop-free performance. Upon clock error or system  
power failure, the device digitally attenuates the data  
(or last known good data), then mutes the analog  
circuit  
•
•
•
Internal Pop-Free Control For Sample-Rate  
Changes Or Clock Halts  
Single Supply Operation:  
Compared with existing DAC technology, the  
PCM510x family offers up to 20dB lower out-of-band  
noise, reducing EMI and aliasing in downstream  
amplifiers/ADCs. (from traditional 100kHz OBN  
measurements all the way to 3MHz)  
–
3.3V Analog, 3.3V Digital

•
3.3V Failsafe LVCMOS Digital Inputs  
Small 20-pin TSSOP Package  
The PCM510x accepts industry-standard audio data  
formats with 16- to 32-bit data. Sampling rates up to  
384kHz are supported.
