Parameters
Complete ADS8688 application solution module
The module only requires a single power supply (2.7-5.5Vdc), excellent power performance, and a typical operating current of 33mA at 3.3V.
The maximum output data volume is 500Ksps/16Bit.
Featuring 8-channel input and 1-channel AUX (direct ADC input), each channel can be individually configured with input range and polarity, supporting input ranges of ± 2.56V, ± 5.12V, ± 10.24V,+5.12V, and+10.24V.
Internal or external reference sources can be configured through resistor jumpers.
Provide a demonstration program.

Question: Does each channel have an independent 500ksps data update rate?
Answer: ADS8688 only has one SAR ADC with 500ksps, so the total data update rate of the 8 channels is 500ksps. ADS8688 has an automatic scan conversion mode, which can automatically switch channels and convert when multiple channels are converted.
Question: How to choose between ADS8688 and AD7606:
Answer: ADS8688 can switch 8 channels through MUX, so it is asynchronous conversion. However, ADS8688 has PGA for each channel, which allows flexible configuration of input range and polarity. For detailed differences, please refer to the corresponding specification sheet.
