EVAL-CN0355-PMDZ

EVAL-CN0355-PMDZ is a CN0355 circuit evaluation board. The circuit is a complete, low power signal conditioner for a bridge type sensor and includes a temperature compensation channel. This circuit is ideal for a variety of industrial pressure sensors and load cells that operate with drive voltages of between 5V and 15V. The circuit can process full-scale signals from approximately 10mV to 1V, using the internal programmable gain amplifier (PGA) of the 24-bit, sigma-delta (Σ-Δ) ADC, making it suitable for a wide variety of pressure sensors. The entire circuit uses only three ICs and requires only 1mA (excluding the bridge current). A ratiometric technique ensures that the accuracy and stability of the system does not depend on a voltage reference.
