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 TLC5615CDG4 is 20 MHz. Exceeding this frequency may result in incorrect DAC output or device malfunction.
Yes, the TLC5615CDG4 can be used in a multiplexed configuration. However, ensure that the multiplexing frequency is within the device's specified clock frequency range and that the input signals are properly synchronized to prevent data corruption.
The power-down mode (PD) pin should be tied to VCC or VREF through a pull-up resistor to ensure proper device operation. When PD is low, the device enters power-down mode, reducing power consumption. When PD is high, the device is active and operational.
