AD5424 datasheet

 

Description :

The AD5424/AD5433/AD5445 are CMOS 8-, 10-, and 12-bit current output digital-to-analog converters (DACs), respectively. These devices operate from a 2.5 V to 5.5 V power supply,making them suitable for battery-powered applications and many other applications. These DACs utilize data readback, allowing the user to read the contents of the DAC register via the DB pins. On power-up, the internal register and latches are filled with 0s and the DAC outputs are at zero scale. As a result of manufacturing with a CMOS submicron process, they offer excellent-quadrant multiplication characteristics, with large signal multiplying bandwidths of up to 10 MHz. The applied external reference input voltage (VREF) determines the full-scale output current. An integrated feedback resistor (RFB) provides temperature tracking and full-scale voltage output
when combined with an external I-to-V precision amplifier.

WM8501 24-bit 192kHz Stereo DAC with 1.7Vrms Line Driver Description The WM8501 is a high performance stereo DAC with an integrated 1.7Vrms line driver. It is designed for audio applications that require a high voltage output along with enhanced load drive capability. The WM8501 supports data input word lengths from 16 to 24-bits and sampling rates up to 192kHz. The WM8501 consists of a serial interface port, digital interpolation filters, multi-bit sigma delta modulators and stereo DAC in a 14lead SOIC package.

The hardware control interface is used for the selection of audio data interface format, enable and de-emphasis. The WM8501 supports I2S, right Justified or DSP interfaces. Operating on separate analog and digital supplies the WM8501 offers very lower power consumption from the digital section, whilst supporting enhanced load drive from the analogue output.

Features

1. Stereo DAC with 1.7Vrms line driver from 5V analogue supply

2. Audio performance
(1) 100dB SNR (‘A’ weighted @ 48kHz)
(2) -88dB THD

3. DAC Sampling Frequency: 8kHz – 192kHz

4. Pin Selectable Audio Data Interface Format
(1) I2S, 16-bit Right Justified or DSP

5. 14-lead SOIC package

6. 4.5V – 5.5V analogue, 2.7V – 5.5V digital supply operation
