AD7705BR Frequently Asked Questions (FAQ)
-
The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital supplies (DVCC and OVCC). This ensures that the analog and digital sections of the device power up correctly.
-
To optimize noise performance, use a low-noise voltage reference, minimize digital noise coupling, and use a quiet analog power supply. Additionally, use a capacitor on the REFIN pin to filter out high-frequency noise.
-
The SYNC pin is used to synchronize the conversion process with an external clock signal. This allows multiple AD7705BR devices to be synchronized, ensuring that conversions occur simultaneously.
-
Yes, the AD7705BR can be used with an external amplifier to increase the input signal amplitude. However, ensure that the amplifier's output impedance is low enough to drive the AD7705BR's input impedance.
-
Use external protection diodes or voltage clamps to limit the input voltage to within the specified range. Additionally, consider using a voltage limiter or a resistive divider network to attenuate the input signal.
