The recommended power-on sequence is to apply VCC first, followed by VREF, and then the input signals. This ensures proper device operation and prevents latch-up or incorrect output states.
To ensure accurate DAC output voltage levels, make sure to use a stable and accurate voltage reference (VREF) and maintain a low impedance output load. Additionally, consider using an external output buffer amplifier if the output load requires a high current drive.
The maximum clock frequency for the TLC5618AIP is 20 MHz. Exceeding this frequency may result in incorrect data conversion or device malfunction.
Yes, the TLC5618AIP can be used in a multiplexed configuration. However, ensure that the multiplexer is properly synchronized with the DAC's clock signal and that the output settling time is sufficient to prevent output glitches.
The power-down mode (PD) pin should be tied to a logic high (VCC) or left open-circuit during normal operation. When PD is pulled low, the device enters a low-power standby mode, and the output is high-impedance. Ensure that the PD pin is properly driven to prevent unwanted device shutdown.
