AD5144ABRUZ100-RL7 Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD first, followed by VREF, and then the digital interface (SDA and SCL) to prevent any unwanted writes to the device.
  • To ensure accurate voltage output, it is essential to decouple the VREF pin with a 10uF capacitor to ground, and use a low-noise, low-impedance voltage source for VREF.
  • The maximum capacitance recommended on the VOUT pin is 100nF to prevent oscillations and ensure stability.
  • During power-up, the I2C bus should be held in a high-impedance state until VDD reaches 1.8V. During power-down, the I2C bus should be held in a high-impedance state until VDD falls below 1.5V.
  • The thermal impedance of the AD5144 package is 30°C/W (junction-to-ambient) and 10°C/W (junction-to-case).
