2 / 16 page 1999 Apr 29 2 Philips Semiconductors Product specification Octuple 6-bit DACs with I2C-bus TDA8444; TDA8444T; TDA8444AT 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. 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 ⁄64VMAX. At power-on all DACs are set to their lowest value. QUICK REFERENCE DATA ORDERING INFORMATION SYMBOL PARAMETER CONDITIONS MIN. TYP. MAX.
