Beschreibung

TIDA-01063 is a reference design for current sensing using a PCB Rogowski Coil sensor to achieve very good linearity for wide measurement range at very low system BOM cost. PCB Rogowski sensor is advantageous for isolated current measurement due to very high bandwidth of 20 MHz and fast settling time of 50 ns. Auto-zeroing, 12nV/√Hz noise density of INA188 makes it suitable to achieve 12 bit system resolution for full scale current of 1000 A. Using simple IIR digital integration algorithm and scalable sampling rate it is possible to achieve better magnitude and phase response.
