Do not load externally. 16 VDD5V S Positive Supply Voltage, 3.0 to 5.5 V Table 1: Pin description SSOP16 DO_OD digital output open drain S supply pin DI_PD digital input pull-down DO_T digital output /tri- state DI_PU digital input pull-up ST schmitt-trigger input AI analog input AO analog output DI digital input 5.1 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). See section 9. Pin 3 Chip Select (CSn; active low) selects a device for serial data transmission over the SSI interface. A “logic high” at CSn forces output DO to digital tri- state. Pin 4 CLK is the clock input for serial data transmission over the SSI interface (see section 8) Pin 6 DO (Data Out) is the serial data output during data transmission over the SSI interface (see section 8) Pin 8 PROG_DI is used to program the different operation modes, as well as the zero-position in the OTP register. This pin is also used as a digital input to shift serial data through the device in Daisy Chain Configuration, (see page 6). 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 (Vout) will be ratiometric to the voltage on this pin. 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. |
