Other Parts Discussed in Thread: ADS7953, ADS7952, ADS1158

Hello,

            Do we have suggest 12-16 channel ADC to meet below customer voltages? Resolution is not critical. Thank you. 

              

0.6V, 1.2V. 0.8V, 12V, 3.3V, 1.5V

    Please take look at ADS7952 / ADS7953 devices. These are 12/16 channel, 12 bit, 1MSPS ADC. It addresses most of the input voltage range you are asking for except 12V. for anything above 5V input range you can use resistor divider scaling at the input of ADS7953

    Thanks & Regards

    Patrick,


    Another possibility would be the ADS1158. This ADC is a 16-bit device, with a multiplexer at the front to make 16 measurements referenced to a common input. As with the devices that Abhijeet mentions, anything over a 5V input range would require some sort of voltage divider to get within the input range of the device.
