Texas Instruments recommends following a star-grounding layout, keeping analog and digital grounds separate, and using a solid ground plane to minimize noise. Additionally, keep the input and output traces short and away from each other to reduce crosstalk.
Use a high-quality, low-ESR capacitor (e.g., 10uF ceramic) as close as possible to the VCC pin, and a smaller capacitor (e.g., 100nF) near the AVCC pin. Ensure the power supply is clean and regulated, and consider adding a ferrite bead or inductor in series with the power supply to filter out high-frequency noise.
The TLV5620IDRG4 can operate up to 50 MHz, but the maximum clock frequency depends on the specific application and the quality of the clock signal. In general, it's recommended to keep the clock frequency below 20 MHz to ensure reliable operation and minimize jitter.
The TLV5620IDRG4 can source up to 30mA per channel, but it's recommended to limit the output current to 10mA per channel to ensure reliable operation. When driving heavy loads, consider adding an external buffer or amplifier to increase the output current capability.
The TLV5620IDRG4 is specified to operate from -40°C to 125°C, but it's recommended to operate within the -20°C to 85°C range for optimal performance and reliability. Operating outside this range may affect the device's accuracy, stability, and lifespan.
