PGA305: PGA305 recommended Thermistor

Part Number: PGA305

Hi professional,

My customer consider to use TMP61 for PGA305's thermistor. Is it possible?

Moreover, Do you have any recommended thermistor for PGA305?

Best regards,

Kazuki Kuramochi

  • Hello Kazuki,

    The TMP61 thermistor would work in this application. However, the maximum current output of 500uA should not be used in this case because of the high resistance of the thermistor (10k). With 5V across the thermistor, the internal current source will run out of headroom and will not be able to regulate the current. Using 100uA would be preferred.

    Regards,
