AS5510 − Register Description

Figure 20:

Name

Description

00h, 01h

D9 to D0

10 Bit ADC output value that corresponds to the magnetic field

input

01h

Parity

Even parity bit calculated from D9 to D0

01h

OCF

Offset compensation loop status

0 = Offset compensation loop in use

1 = Offset compensation loop has finished

02h

Power down mode

0 = Normal operation (Default)

1 = Power Down mode.

02h

Polarity

Output signal polarity

0 = Normal polarity (Default)

1 = Reversed polarity (reversed magnet)

02h

Fast / Slow mode

0 = Fast mode (Default)

1 = Slow mode. Enables averaging of the output values (reduced

noise, better repeatability slower sampling frequency. See

Electrical and Magnetic Specifications

03h, 04h

Offs9 to Offs0

Contains the offset compensation value. For read access only.

Don't modify the register values.

0Bh

Sensitivity

Sensitivity setting

0h = Input range ± 50mT Sensitivity = 97.66μT/LSB (Default)

1h = Input range ± 25mT Sensitivity = 48.83μT/LSB

2h = Input range ± 12.5mT Sensitivity = 24.41μT/LSB

3h = Input range ± 18.75mT Sensitivity = 36.62μT/LSB
