The recommended power-up sequence is to apply VDD first, followed by VREF, and then the digital inputs. This ensures proper device operation and prevents potential latch-up conditions.
To ensure accurate voltage output, it's essential to use a low-noise, low-impedance voltage reference (VREF) and to decouple the VREF pin with a capacitor. Additionally, ensure that the output load is within the specified range, and the output voltage is not loaded beyond the maximum capacitive load.
The maximum clock frequency for the DAC104S085 is 40 MHz. However, the actual clock frequency may be limited by the specific application and the quality of the clock signal.
To enter power-down mode, assert the PD pin low. In this mode, the DAC output is disconnected from the output pin, and the device consumes minimal power. When exiting power-down mode, ensure that the PD pin is de-asserted before applying a new input code to prevent output glitches.
The DAC104S085's performance is affected by temperature, with the output voltage and linearity varying with temperature. The device is specified to operate over a temperature range of -40°C to 125°C, and the user should consider these variations when designing their application.
