TDA8444T/N4/G1,512

Digital To Analog Converters Overview

The TDA8444T/N4/G1,512 is an octuple 6-bit digital-to-analog converter featuring an I²C-bus interface. It operates within a supply voltage range of 4.5 V to 13.2 V and includes eight push-pull outputs with short-circuit protection. The maximum output voltage is determined by the VMAX input pin, allowing adjustable common output swing. Each DAC accepts a 6-bit word to select one of 64 values, providing approximately 1/64VMAX resolution. The device supports three programmable slave address bits for multi-device bus configurations.

Digital To Analog Converters Feature Summary

• Eight independent 6-bit DACs with push-pull outputs
• I²C-bus slave receiver with programmable addressing
• Adjustable output voltage via external VMAX control
• Short-circuit protection on all analog outputs

Digital To Analog Converters Applications

• Multi-channel signal generation systems
• Industrial process control interfaces
• Audio or video level adjustment circuits

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix G1,512 against manufacturer documentation to confirm packaging and reel specifications. Ensure compatibility with existing I²C bus voltage levels, as SDA and SCL pins are protected by zener diodes limiting normal bus line voltage to 5.5 V. Confirm thermal management requirements based on the SO16 package thermal resistance characteristics.

Digital To Analog Converters Selection Notes

Select this component when multiple low-resolution analog outputs are required from a single serial interface. The VMAX pin allows scaling the full-scale output range independently of the supply voltage. Consider the 6-bit resolution limit for applications requiring higher precision. Verify that the capacitive load on outputs does not exceed 2 nF to prevent oscillation issues.

Digital To Analog Converters Part Context

This part belongs to the TDA8444 family of octuple DACs manufactured by NXP (formerly Philips Semiconductors). The TDA8444T variant specifically denotes the SO16 plastic small outline package. Other variants in the series include the DIP16 TDA8444 and the SO20 TDA8444AT, which offer additional address bit availability.

Digital To Analog Converters Replacement Considerations

Direct replacements include the TDA8444AT for increased addressability in the SO20 package or the TDA8444 for through-hole mounting. Verify pinout compatibility, particularly regarding the A2 address bit presence in the SO16 versus SO20 packages.
