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 recommended to use an external op-amp to buffer the output and ensure a stable voltage range. Additionally, consider using a voltage divider or attenuator to adjust the output voltage to the desired range.
The maximum update rate for the DAC8165 is 1 MSPS (million samples per second). However, this rate may vary depending on the specific application, clock frequency, and digital interface used.
To implement a bipolar output, use an external op-amp to invert and scale the output voltage. You can also use a voltage offset circuit to shift the output voltage range to the desired bipolar range.
The DAC8165's performance is affected by temperature, with changes in offset voltage, gain error, and linearity. It's essential to consider temperature compensation and calibration in your design to ensure accurate performance over the desired temperature range.
