Is there high temp version of ADC124S021?

Other Parts Discussed in Thread: ADC124S021, ADS7950

Hi,

My customer is looking for 4channel ADC with 200kHz, 12bit resolution. I found ADC124S021 but its temp spec is -40 to 85. However, my customer wants -40 to 125 temp spec device. Is there any suitable device or roadmap device?

Regards,

  • Hi Victor

    You can take look at ADS7950. Its 12 bit, 4 channel 1MSPS SAR ADC with temp range of -40C to 125C.

    Please let me know if you need additional information regarding ADS795x family

    Thanks & Regards
