1) Your website page for the ADS1243-HT lists the ADS1278-HT as a recommended alternative. Does this mean TI doesn't recommend the 1273? and why (end of life, other reasons etc) [CY] ADS1273 does not exist at TI. Did you mean ADS1243-HT ? Because the website recommends possible alternative parts does not mean the device for which you searched is not recommended. This is just a marketing tool to advertise other similar devices. 2) in the 1243 datasheet i struggled to really understand the maximum sample rate - i think its 15Hz or less? (my application needs to sample all 8 channels at 400Hz) - could you confirm the maximum sample rate [CY] fdata is the sample rate which is 15Hz max for the ADS1243-HT . So based on your requirements, this is not a viable solution. 3) are there any other high temp ADC with self calibration and can sample at 400sps (but i would like the option to go to 10ksps) [CY] The only other -HT ADC is the ADS1282-SP but it is 2 channels that are mux'd and you mention 8 channels. Thanks Christian
