Hello,I'm looking for a (SAR) ADC with the following features- This must be pseudo differential true bipolar or differential true bipolar- SPI interface- 16 bits- Nice would be 1 channel- about 10 MSPSI can only find the LTC2328-16 (1MSPS). Unfortunately he does not have a higher MSPS.
Do you have suggestions or an alternatives ADC with higher MSPS?best regards,
The LTC2370-16 will not provide the performance you are looking for above fin=100kHz. See the typical performance curves on page 6 of the LTC2370-16 data sheet.
You might consider the LTC2385-16. SNR and THD performance are within your desired specs well beyond 500kHz.
Using the AD8139 differential ADC driver you should be able to take your single-ended true bipolar signal and convert it to a differential signal, compatible with the signal levels of the LTC2385-16. See Figure 61 as an example on page 21 of AD8139 data sheet.
