This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

APPLICATIONS

•

A/V Receivers

•

DVD, BD Players

Applications Requiring 2VRMS Audio Output

DESCRIPTION

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.

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.

The integrated line driver surpasses all other charge-pump based line drivers by supporting loads down to 1k

Ω.

By supporting loads down to 1k

Ω, the PCM510x can essentially drive up to 10 products in parallel, such as an

LCD TV, DVDR, AV Receivers and other devices.

The integrated PLL on the device removes the requirement for a system clock (commonly known as master

clock), allowing a 3-wire I2S connection and reducing 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

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)

The PCM510x accepts industry-standard audio data formats with 16- to 32-bit data. Sample rates up to 384kHz

are supported.
