Please help to find the best ADC part with the below specifications:
Dual supply : +5V and -5V
Input Channel : 2, single ended
Sampling rate :10 -50 KSPS
Resolution :12 Bit
Thanks & regards,
You can check the ADAQ7980 and ADAQ7988 or the AD7655(AD765x family) which are 6 channels 16 bits 250ksps ADCs. You can refer to the link for the short list of parametric search.
There is another option to use a single supply ADC, you just need to have an amplifier in the front end and bias the amplifier so the the voltage to the ADC will scaled for ADCs input range.
