Application Scenarios & Design Considerations

Octuple 6-bit DACs with I2C-bus

Alternative Part Number

  • DS1804Z-010+ --: Single digital potentiometer with I2C-compatible interface, functionally similar to the TDA8444AT for volume/level control applications.
  • MCP4551-103E/MS --: Single-channel I2C digital potentiometer with 10k ohm resistance, suitable replacement for analog adjustment functions.
  • AD5241BRZ10 --: I2C-compatible digital potentiometer offering comparable multi-channel control functionality in a similar package.
  • PCF8574T --: I2C 8-bit I/O expander in the same DIP/SO package family, widely used as a functional substitute for the TDA8444 I2C DAC/expander in control applications.
  • MCP23008 --: I2C 8-bit I/O expander with comparable interface and supply range, suitable as a drop-in functional replacement in I2C-based control designs.
  • PCA9554 --: 8-bit I2C I/O expander with similar pinout and voltage range, offering equivalent I2C control functionality for legacy Philips designs.
  • PCF8574AP --: I2C 8-bit I/O expander with interrupt output, close functional match and easy drop-in for many TDA8444AT use cases.
  • MCP23008-E/SO --: I2C 8-bit I/O expander with configurable registers, a common cross-vendor alternative when the original Philips part is unavailable.
