Part Number: ADS1115
Current design includes an ADS1115 but I am finding the non-linearity at upper end of the range to diviate too much.
I am looking for an ADC that can handle an single sided input which ranges from -5 to 5VDC (or greater). I am not providing the current board design as it will be changed as nessicary to optimize the new ADC.
Ideal characterists are as follows:
- SPI and/or I2C
- minimum input range of -5 to 5VDC (greater is prefered if accuracy/resolution is maintained)
- +5V and +12V rails available
- high resolution (12bit or greather)
- mV accuracy
- low noise
- as linear as possible
- throuhole is always prefered, but surface mount is acceptable
