DAC8871SPW datasheet by Texas Instruments

DAC8871SPW Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC8871SPW?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital supply (DVCC). This ensures that the analog and digital circuits are properly biased before the device is enabled.
• How do I ensure accurate voltage output from the DAC8871SPW?
  To ensure accurate voltage output, it is essential to use a high-precision voltage reference, such as the Texas Instruments REF5025. Additionally, the output voltage should be filtered using a low-pass filter to reduce noise and ripple.
• What is the maximum output current of the DAC8871SPW?
  The maximum output current of the DAC8871SPW is 10 mA. Exceeding this current limit may cause the device to overheat or malfunction.
• How do I interface the DAC8871SPW with a microcontroller?
  The DAC8871SPW can be interfaced with a microcontroller using a serial peripheral interface (SPI) or an inter-integrated circuit (I2C) interface. The device requires a clock signal, chip select signal, and data input signals to operate.
• What is the settling time of the DAC8871SPW?
  The settling time of the DAC8871SPW is typically 10 μs, but it can vary depending on the output voltage, load capacitance, and other factors. It is essential to ensure that the device has sufficient settling time to achieve accurate output voltages.
