PCM1803DB datasheet

Description

The PCM1803DB is high-performance, low-cost, single-chip stereo analog-to-digital converter with single-ended analog voltage input. The PCM1803 uses a delta-sigma modulator with 64-, 128-times oversampling, and includes a digital decimation filter and high-pass filter which removes the DC component of the input signal. For various applications, the PCM1803 supports master and slave modes and four data formats in serial interface. The PCM1803 is suitable for a wide variety of cost-sensitive consumer applications where good performance and operation from a 5-V analog supply and 3.3-V digital supply are required.

TAS5705 datasheet

Description

The TAS5705 is a 20-W, efficient, digital audio power amplifier for driving stereo bridge-tied speakers. Two serial data inputs allow processing of up to four discrete audio channels and seamless integration to most digital audio processors and MPEG decoders. The device accepts a wide range of input data and clock rates. A fully programmable data path allows these channels to be routed to the internal speaker drivers or output via the line-level subwoofer or headphone PWM outputs.

The TAS5705 is a slave-only device receiving clocks from external sources. The TAS5705 operates at a 384-kHz switching rate for 32-, 48-, 96-,and 192-kHz data and 352.8-kHz switching rate for 44.1-, 88.2- and 176.4-kHz data. The 8× oversampling combined with the fourth-order noise shaper provides a flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.
