TDA8444; TDA8444T; TDA8444AT
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.
