Produktoversigt

The DS1882Z-050+ is a dual, non-volatile, logarithmic audio digital potentiometer in 16 pin NSOIC package. This device is designed to operate in audio systems that accommodate up to ±7V signal levels. The potentiometer settings can be stored in EEPROM so that they are retained when the power is cycled. The DS1882 has separate supplies for the potentiometers (VCC) and the communication circuitry (VDD). For clickless/popless operation, a zero-crossing detector allows the wiper position to change when there is no voltage across the potentiometer. The device has two attenuation configuration options provide optimum flexibility for the specific applications. Option 1 provides 63 logarithmic tapered steps (0dB to -62dB, 1dB/step) plus a mute setting and Option 2 has 32 logarithmic steps plus mute and provides software compatibility with the DS1808.
  • Supply voltage range is 4.5V to 7V
  • Operating temperature range from -40°C to 85°C
  • I2C compatible interface
  • Potentiometer settings are configurable as non-volatile or volatile
  • Low THD+N and minimizes crosstalk
  • 0.5dB channel to channel matching to prevent volume differences between channels
  • Zero crossing detector eliminates switching noise
  • Three address pins allow up to 8 devices on I2C bus
  • End to end resistance is 45Kohm at ±20% tolerance and temperature coefficient is 750ppm/°C
  • Ratiometric temperature coefficient of 30ppm/°C
