MAX9938TEBS+TG45 Frequently Asked Questions (FAQs)

  • A good PCB layout for the MAX9938TEBS+TG45 involves keeping the input and output traces short and away from noise sources, using a solid ground plane, and placing decoupling capacitors close to the device. A 4-layer PCB with a dedicated ground plane is recommended. Refer to the application note AN-1149 for more details.
  • To ensure accuracy, calibrate the device using a precision temperature source, and ensure that the thermistor is properly connected and not subject to self-heating. Also, use a low-noise power supply and minimize digital noise coupling to the analog inputs.
  • The maximum cable length for the thermistor input depends on the cable type and the noise environment. As a general guideline, keep the cable length as short as possible (less than 1 meter) and use a shielded cable to minimize noise pickup. If longer cables are necessary, use a differential input configuration and a low-capacitance cable.
  • No, the MAX9938TEBS+TG45 is designed to work with thermistors, not thermocouples. Thermocouples require a different type of signal conditioning and amplification, and the MAX9938TEBS+TG45 is not compatible with thermocouples.
  • The MAX9938TEBS+TG45's internal registers can be programmed using the I2C interface. Refer to the datasheet for the register map and programming instructions. You can use a microcontroller or a dedicated I2C programmer to access and modify the registers.
