The recommended power-up sequence is to apply the analog supply voltage (AVDD) first, followed by the digital supply voltage (DVDD) and then the clock signal. This ensures proper initialization of the device.
To optimize the analog input impedance, use a source impedance of 50 ohms or less, and ensure that the input signal is properly terminated. Additionally, consider using a buffer amplifier or an impedance-matching network to minimize signal reflections.
The ADS5240IPAP supports clock frequencies up to 160 MHz. However, the maximum clock frequency may vary depending on the specific application and system requirements.
The ADS5240IPAP outputs data in a 14-bit, two's complement format. To handle the output data, ensure that your system is configured to receive and process 14-bit data words, and consider using a FIFO or buffer to manage data transfer.
The typical power consumption of the ADS5240IPAP is around 350 mW at a clock frequency of 100 MHz. However, actual power consumption may vary depending on the specific application, clock frequency, and operating conditions.
