STT818B Frequently Asked Questions (FAQ)
-
A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a 10nF decoupling capacitor between VCC and GND, and a 100nF capacitor between AVCC and AGND.
-
Use a thermocouple or a thermistor with a high accuracy rating. Ensure good thermal contact between the sensor and the device under test. Use a low-pass filter to remove noise and ensure the measurement frequency is within the device's bandwidth.
-
The maximum cable length for the I2C interface depends on the clock frequency and the capacitance of the cable. As a general rule, keep the cable length below 1 meter for frequencies up to 400 kHz. Use a repeater or a buffer if longer cable lengths are required.
-
The POR and BOR are triggered by a power-on event or a voltage drop. Ensure a stable power supply and add a capacitor to the VCC pin to filter out noise. Use a reset supervisor IC or a microcontroller with a built-in POR and BOR to handle these events.
-
The recommended clock frequency for the I2C interface is up to 400 kHz. However, the device can operate at higher frequencies with proper signal conditioning and a high-quality clock source.
