The PCM510x-Q1 family is a series of monolithic CMOS integrated circuits that include a stereo digital-to-analog converter and additional support circuitry in a small TSSOP package. The PCM510x-Q1 uses the latest generation of TI’s advanced segment-DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter.

The PCM510x-Q1 provides 2.1-VRMS ground-centered outputs, allowing designers to eliminate not only dc blocking capacitors on the output, but also 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 1 kΩ. By supporting loads down to 1 k&3937;, the PCM510x-Q1 can essentially drive up to 10 products in parallel (LCD TV, DVDR, AV receivers, and so on).

The integrated PLL on the device removes the requirement for a system clock (commonly known as master clock). This allows a three-wire I2S connection, along with reduced system EMI.

Intelligent clock error and PowerSense undervoltage protection uses a two-level mute system for pop-free performance. On 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-Q1 offers up to 20-dB lower out-of-band (OBN) noise, reducing EMI and aliasing in downstream amplifiers/ADCs. (from traditional 100-kHz OBN measurements all the way to 3 MHz)

The PCM510x-Q1 accepts industry-standard audio data formats with 16- to 32-bit data and supports sSample rates up to 384 kHz.
