The recommended power-up sequence is to apply VDD first, followed by AVDD, and then the analog input signals. This ensures proper device operation and prevents latch-up.
To optimize the analog input impedance, use a source impedance of 1 kΩ or less, and ensure the analog input signal is properly terminated. This minimizes signal reflections and ensures accurate conversions.
The maximum clock frequency for the ADS5521IPAP is 40 MHz. Exceeding this frequency may result in reduced performance, increased power consumption, or even device damage.
Yes, the ADS5521IPAP can be used in a multi-channel application. However, each channel requires a separate device, and the devices must be properly synchronized to ensure accurate conversions.
The ADS5521IPAP outputs 14-bit digital data in a binary two's complement format. The data should be handled as unsigned integers, and the most significant bit (MSB) should be used to determine the sign of the output value.
