The recommended power-up sequence is to apply VDD first, followed by VREF, and then the digital supply (VCC). This ensures proper device operation and prevents potential latch-up conditions.
The DAC8165 has a rail-to-rail output stage, but it's not guaranteed to swing all the way to the supply rails. To ensure maximum output voltage range, use an external op-amp to buffer the output and provide additional gain if needed.
The maximum clock frequency for the DAC8165 is 40 MHz. However, the actual achievable clock frequency may be limited by the specific application, PCB layout, and noise considerations.
To achieve a bipolar output voltage range, use an external inverting amplifier stage with a gain of -1. This will allow the DAC8165 to generate a bipolar output voltage range centered around 0V.
The DAC8165's performance is affected by temperature, with changes in offset voltage, gain error, and linearity. Ensure proper temperature compensation and calibration in your design to minimize these effects.
