tON Power-on time (see Figure 17) B = 0 mT, no load on OUT 175 330 µs
fBW Sensing bandwidth 20 kHz
td Propagation delay time From change in B to change in OUT 10 µs
BND Input-referred RMS noise density VCC = 5 V 130 nT/√Hz
VCC = 3.3 V 215
BN Input-referred noise BND × 6.6 × √20 kHz VCC = 5 V 0.12 mTPP
VCC = 3.3 V 0.2
VN Output-referred noise(2) BN × S DRV5055A1/Z1 12 mVPP
DRV5055A2/Z2 6
