The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures proper device operation and prevents latch-up.
To ensure accurate voltage output, it is essential to use a stable reference voltage, minimize noise on the analog input pins, and use a low-noise power supply. Additionally, consider using a voltage reference buffer amplifier to improve output accuracy.
The maximum clock frequency for the DAC908E/2K5 is 40 MHz. Exceeding this frequency may result in incorrect data conversion or device malfunction.
The output voltage settling time of the DAC908E/2K5 is typically around 10 μs. To ensure accurate output voltage, wait for the settling time to elapse before taking a measurement or using the output voltage in your application.
Yes, the DAC908E/2K5 can be used in a ratiometric configuration, where the reference voltage is derived from the power supply voltage. However, this configuration may affect the output voltage accuracy and linearity.
