The optimal clock frequency for the ADS42B49IRGCT is between 10 MHz to 50 MHz. However, the device can operate up to 100 MHz, but with reduced performance.
To optimize the analog input impedance, use a source impedance of 1 kΩ or less, and ensure the analog input signal is properly terminated with a 50 Ω resistor to ground.
The recommended power-up sequence is to apply the analog power supply (AVDD) first, followed by the digital power supply (DVDD), and then the clock signal.
The ADS42B49IRGCT outputs data in a 14-bit, two's complement format. Ensure your digital system is configured to handle this format correctly.
The maximum input voltage range for the ADS42B49IRGCT is ±VREF (typically 2.5 V). Ensure the input signal does not exceed this range to avoid damage to the device.
