Other Parts Discussed in Thread: ADS8665 I use the ADS8665 chip. And i want to read analog data (voltage)
The experiment environment:
1. I send the 5 voltage in Analog Ch 1 by function generator.
2. I turn on the power.
3. I send the command…
Hello Takashi,
Your understanding is correct, ADS8506IB has smaller INL,DNL and Full Sclae Error. The new SAR ADCs which can cover +/-10V bipolar and unipolar input include ADS8661 (12-Bit, 1.25mSPS), ADS8665 (12-Bit, 500ksps), also 14-Bit ADS867x and…
Hi Takashi,
1. I did not see any risk to use a ceramic cap for the power supply, ceramic caps are frequently used on our EVM boards.
2. The analog power supply is very important for data conversion because it can directly affect your measured performance…
Dale, I was explicitly referring to the ADS8661/5 and their timing. However, I erroneously took the conversion time, not the acquisition time for the calculation (on the ADS8665, both are the same anyway).
Of course, the device doesn't need SPI clocks…
Hi Howard,
Can you provide more details on what you need to help narrow down a good recommendation?
1. Is there a preferred digital interface, SPI, I2C, parallel?
2. What input voltage range would be helpful? (Do you need bipolar inputs or is 0…
