General description

The interface circuit is a bipolar IC in a DIP16, SO16, or SO20 package made in an I2L-compatible 18 V process.

The TDA8444 contains eight programmable 6-bit DAC outputs, an I²C-bus slave receiver with three (two for SO16) programmable address bits and one input (VMAX) to set the maximum output voltage. Each DAC can be programmed separately by a 6-bit word to 64 values, but VMAX determines the maximum output voltage for all DACs. The resolution will be approximately 1/64 VMAX.

At power-on all DACs are set to their lowest value.

Features

  • Eight DACs with 6-bit resolution
  • Adjustable common output swing
  • Push-pull outputs
  • Outputs short-circuit protected
  • Three programmable slave address bits
  • Large supply voltage range
  • Low temperature coefficient.
