Description
- Application Circuit is a completely isolated 12-bit, 300 kSPS RTD temperature measuring system that uses only three active devices. The system processes the output of a Pt100 RTD and includes an innovative circuit for lead-wire compensation using a standard 3-wire connection. The circuit operates on a single 3.3V supply. The total error after room temperature calibration is less than ±0.24% FSR for a ±10 oC change in temperature, making it ideal for a wide variety of industrial temperature measurements
