Data Sheet
6.1 Pin Description
Pins 7, 15 and 16 are supply pins, pins 5, 13 and 14 are for internal use and must be left open.
Pin 1 is the magnetic field strength indicator, MagRNGn. It is an open-drain output that is pulled to VSS when the
magnetic field is out of the recommended range (45mT to 75mT). The chip will still continue to operate, but with
reduced performance, when the magnetic field is out of range. When this pin is low, the analog output at pins #10 and
#12 will be 0V to indicate the out-of-range condition.
Pin 2 MODE allows switching between filtered (slow) and unfiltered (fast mode). This pin must be tied to VSS or
VDD5V, and must not be switched after power up. See section 12.
Pin 3 Chip Select (CSn; active low) selects a device for serial data transmission and enables the Vout output. A “logic
high” at CSn forces output SDA to digital tri-state, and force Vout to 0V.
Pin 4 SCL (Serial Clock) is the clock input for data transmission over the 2-wire serial interface
Pin 6 SDA (Serial Data Line) is the serial data input / output line during data transmission over the 2-wire interface
Pin 8 PROG is used to program the different operation modes, as well as the zero-position in the OTP register.
Pin 9 DACref is the external voltage reference input for the Digital-to-Analog Converter (DAC). If selected, the analog
output voltage on pin 12 (V
) will be ratiometric to the voltage on this pin.
out
Pin10 DACout is the unbuffered output of the DAC. This pin may be used to connect an external OPAMP, etc. to the
DAC.
Pin 11 FB (Feedback) is the inverting input of the OPAMP buffer stage.
Access to this pin allows various OPAMP configurations.
Pin 12 Vout is the analog output pin. The analog output is a DC voltage, ratiometric to VDD5V (3.0 – 5.5V) or an
external voltage source and proportional to the angle.
