Frequently Asked Questions
How can I connect multiple ADS8318 units?
The SPI interface supports a daisy chain configuration, allowing for easy option chaining or cascading of several devices.
What is the typical Signal-to-Noise Ratio (SNR) at 10 kHz?
The device offers a typical SNR of 95.2dB when measured with a 10-kHz differential input.
Is this ADC suitable for battery-powered applications?
Yes, it has low power dissipation, generating about 18 mW typical at 500 KSPS, and the consumption scales linearly with speed.
How should I store the ADS8318 to prevent damage?
Because of its limited built-in ESD protection, leads must be shorted or the device placed in conductive foam during handling and storage.
