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.
