AD7391ARZ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures that the internal voltage regulators are powered up correctly.
  • To ensure accurate voltage output, it is essential to decouple the AVCC pin with a 10uF capacitor to ground, and to use a low-noise, low-impedance power supply. Additionally, the output voltage should be buffered with an op-amp if it needs to drive a load.
  • The maximum output current of the AD7391ARZ is 5mA. Exceeding this current may cause the output voltage to droop or the device to overheat.
  • The AD7391ARZ can be interfaced with a microcontroller using a 3-wire serial interface (SCLK, SDIN, and LDAC). The microcontroller should provide a clock signal on the SCLK pin, and serial data on the SDIN pin. The LDAC pin should be used to latch the data into the AD7391ARZ.
  • The AD7391ARZ is specified to operate over a temperature range of -40°C to +125°C. However, the device may still function outside this range, but its performance may degrade.
