Notes:

2) Typical values denoted with the “±” sign signify ±3 sigma values.

3) Beyond the maximum specified current range (I_P), the current sensor continues to provide an analog output voltage proportional to the

primary current until the device reaches the high or low saturation voltage. However, the nonlinearity increases beyond the specified range

(I_P).

4) The device can operate at higher primary current levels (I_P) and ambient temperatures (T_A), as long as the maximum junction temperature

(T_J(MAX)) is not exceeded.

5) The offset voltage does not incorporate any error due to the external magnetic fields.

6) Guaranteed by design and characterization.

7) The resistance is defined as the total resistance measured from a point of the lead next to the solder joint, assuming that the two IP+ pins

(and IP- pins) have the same potential (see Figure 1). This definition corresponds to the effect resistance used to estimate the joule heating,

calculated with R x I_P
