The recommended power-up sequence is to apply VDD first, followed by VREF, and then the digital supply (VCC). This ensures that the internal voltage regulators are properly biased before the digital circuitry is powered up.
To optimize performance, use a low-noise power supply, decouple the power pins with high-quality capacitors, and use a low-impedance output load. Additionally, ensure that the analog and digital grounds are separated and connected at a single point to minimize noise coupling.
The maximum output current of the TLV320DAC23PWR is 20 mA per channel. Exceeding this current limit can cause the device to overheat and potentially fail.
To configure the TLV320DAC23PWR for differential output operation, connect the OUT+ pin to the positive output of the load, and the OUT- pin to the negative output of the load. Ensure that the load impedance is balanced and that the common-mode voltage is within the specified range.
The recommended clock frequency range for the TLV320DAC23PWR is 2.4 kHz to 50 kHz. Operating the device outside of this range may result in reduced performance or instability.
