TIDA-01606: Current sensor CASR 15-NP Vref connection

Part Number: TIDA-01606

Tool/software:

Hi all,

I am looking at the TIDA-01606 schematics (file: TIDA-01606_POWERCARDE6_SCH.pdf, sheet 3 of 7; file: TIDA-01606-E6_POWERCARD_Current Sensing_Pg5.SchDoc), specifically the AC line current sensing section and I have one question.

As I understand from the LEM datasheet (page 17 of 19), the VREF input should have a 1.65 V reference in order to measure unipolar signals.

Am I missing something? There is a 1.65 V generated in the bottom right corner, but I do not see if this is connected to the VREF input pin.

Thanks, MB
