Product specification
Octuple 6-bit DACs with I
2
C-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 I
2
C-bus slave receiver with three (two for
SO16) programmable address bits and one input (V
MAX
) to
set the maximum output voltage. Each DAC can be
programmed separately by a 6-bit word to 64 values, but
V
MAX
determines the maximum output voltage for all
DACs. The resolution will be approximately
1
64
V
MAX
.
At power-on all DACs are set to their lowest value.
