AD7869JR Frequently Asked Questions (FAQ)
-
A good layout and routing practice for the AD7869JR involves keeping the analog and digital grounds separate, using a star-ground configuration, and placing the analog and digital components on opposite sides of the board. Additionally, it's recommended to use a solid ground plane, keep the signal traces short and direct, and avoid running digital traces near analog traces.
-
The AD7869JR's internal reference voltage can be configured by connecting the REFOUT pin to the REFIN pin through a resistor divider network. The recommended ratio for the resistor divider is 1:1 to 1:2, and the total resistance should be between 1 kΩ and 10 kΩ. Additionally, a 10 nF capacitor should be connected between the REFOUT pin and the analog ground to filter out noise.
-
The maximum sampling rate of the AD7869JR is 250 kSPS, but this can be affected by the clock frequency, conversion mode, and other factors. In general, the maximum sampling rate is achieved when the clock frequency is set to 10 MHz and the conversion mode is set to single-shot mode.
-
The AD7869JR's POR and BOR functions can be handled by connecting a capacitor between the POR/BOR pin and the analog ground. The recommended capacitor value is 10 nF to 100 nF. Additionally, the POR/BOR pin can be connected to a voltage source through a resistor to adjust the reset threshold voltage.
-
A good power supply decoupling scheme for the AD7869JR involves using a combination of ceramic and electrolytic capacitors. A 10 μF electrolytic capacitor should be connected between the AVDD pin and the analog ground, and a 100 nF ceramic capacitor should be connected between the AVDD pin and the digital ground. Additionally, a 10 μF electrolytic capacitor should be connected between the DVDD pin and the digital ground.
