One serial data input allows processing of up to two discrete audio channels and seamless integration to most digital-audio processors and MPEG decoders. The device accepts a wide range of input data and data rates. A fully programmable data path routes these channels to the internal speaker drivers.The TAS5709 is a slave-only device receiving all clocks from external sources. The TAS5709 operates with a PWM carrier between a 384-kHz switching rate and a 352-KHz switching rate, depending on the input sample rate. Oversampling combined with a fourth-order noise shaper provides a flat noise floor and excellent dynamic range from 20 Hz to 20 kHz. The TAS5709A is identical in function to the TAS5709, but has a unique I 2 C device address. The address of the TAS5709 is 0x36. The address of the TAS5709A is 0x3A.

Lowlevel current output devices, such as photosensors, can bedirectly connected to its input. The most stringent accuracy requirements of many unipolar output sensor applications occur at low signal levels. To meet this requirement, Burr-Brown developed the adaptive delta odulation architecture of the DDC101 to provide linearly improving noise and linearity errors as the input signal level decreases. The DDC101 combines the functions of current-to-voltage conversion, integration, input programmable gain amplification, A/D conversion, and digital filtering to produce precision, wide dynamic range results. The input signal can be a low level current connected directly into the unit or a voltage connected through a user selected resistor. Although the DDC101 is optimized for unipolar signals, it can also accurately digitize bipolar input signals. The patented delta modulation topology combines charge integration and digitization functions. Oversampling and digital filtering reduce system noise dramatically. Correlated Double Sampling (CDS) captures and eliminates steady state and conversion cycle dependent offset and switching errors that are not eliminated with conventional analog circuits. The DDC101 block diagram is shown below. During conversion, the input signal is collected on the Internal integration capacitance for a user determined integration period. A high precision, autozeroed comparator samples the analog input node. Tracking logic updates the internal high resolution D/A converter at a 2MHz rate to maintain the analog input at virtual ground. A user programmable digital filter oversamples the tracking logic’s output. The digital filter passes a low noise, high resolution digital output to the serial I/O register. The serial outputs of multiple DDC101 units can be easily connected together in series or parallel if desired to minimize interconnections.
