The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital supply (DVCC). This ensures proper device operation and prevents latch-up.
To ensure accurate voltage output, it is essential to use a high-precision voltage reference, such as the Texas Instruments REF5025. Additionally, ensure that the output voltage is buffered with an op-amp, such as the OPA333, to minimize output impedance and improve load regulation.
The maximum output current capability of the DAC7573IPWR is 5 mA. Exceeding this limit may cause device damage or affect output accuracy.
The DAC7573IPWR's digital interface is a 3-wire serial interface. Ensure that the clock frequency does not exceed 50 MHz, and the CS (chip select) signal is asserted low to initiate data transfer. Also, ensure that the data is transmitted MSB (most significant bit) first.
The internal voltage reference is a 2.5V bandgap reference that provides a stable voltage reference for the DAC. It can be used as a reference for the DAC or as a separate voltage reference for other circuits.
