Hello,

This sample project is the analog front end for sensor.

The inversion amplification with offset in single power supply drive is used to match the sensor signal to the dynamic range of the PSoC AD converter.

Please see the schematics and board.

KitProg3 of CY8CKIT-145-40XX is required for I2C communication with Bridge Panel Control.

1. Create a sine wave output using VDAC with sampling rate of 1ms timer interrupt.

2. It is amplified twice by inverting amplification and 1.2V offset is added.

3. Amplify 4x with PGA and add 1.2V offset too.

   Unfortunately, due to the wiring impedance inside PSoC, the gain is about 3 times, not 4 times.

4. The result of AD conversion is displayed on the Bridge Panel Control. BCP script is also attached.

 If you actually use it, you should use it with a larger gain.

 I hope it helps you.

Best regards,

Yocchi
