Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OR | tri_state | Open-drain output indicating differential amplifier overrange condition when output signal clips; requires external pull-up resistor |
| 2 | REFSEL2 | input | Digital CMOS input for reference voltage selection; used with REFSEL1 to select 2.5V fixed, 1.65V fixed, or 50% VDD ratiometric mode |
| 3 | REFSEL1 | input | Digital CMOS input for reference voltage selection; used with REFSEL2 to select 2.5V fixed, 1.65V fixed, or 50% VDD ratiometric mode |
| 4 | REFOUT | output | Output terminal for selected buffered reference voltage (2.5V, 1.65V, or VDD/2) with load regulation 0.15-0.35 mV/mA and ±5 mA sink/source capability |
| 5 | REFIN | input | Input for zero reference to differential amplifier with 50 kΩ input impedance; normally connect to REFOUT or external reference with optional 4×RSHUNT dummy shunt for CMR |
| 6 | VOUT | output | Output of differential amplifier with 4 V/V gain, 2 MHz bandwidth, 6.5 V/µs slew rate, output swing 48-85 mV from supply rails at 2.5 mA load |
| 7 | IAIN2 | input | Noninverting input of differential amplifier connected to positive shunt terminal with 20 kΩ typical impedance and -1 V to VDD+1 V common-mode input range |
| 8 | IAIN1 | input | Inverting input of differential amplifier connected to negative shunt terminal with 20 kΩ typical impedance and -1 V to VDD+1 V common-mode input range |
| 9 | GND | power_in | Ground connection; connect both GND pins to local ground plane for low impedance |
| 10 | GND | power_in | Ground connection; connect both GND pins to local ground plane for low impedance |
| 11 | ICOMP2 | output | Compensation coil H-bridge driver output with peak current 210 mA at 5 V or 125 mA at 3.3 V and common-mode output at VDD/2 |
| 12 | ICOMP1 | output | Compensation coil H-bridge driver output with peak current 210 mA at 5 V or 125 mA at 3.3 V and common-mode output at VDD/2; add external Schottky diodes for high-current protection |
| 13 | VDD | power_in | Power supply voltage input with operating range 2.7 V to 5.5 V, quiescent current 6 mA at 25°C, power-on reset threshold 2.4 V |
| 14 | GSEL2 | input | Digital CMOS input for Hall amplifier gain and compensation frequency selection; use with GSEL1 to select Gain_1/2/3 modes or external op-amp mode |
| 15 | GSEL1 | input | Digital CMOS input for Hall amplifier gain and compensation frequency selection; use with GSEL2 to select Gain_1/2/3 modes or external op-amp mode |
| 16 | ERROR | tri_state | Open-drain output indicating error conditions including power-on reset, brownout >25 µs, Hall sensor offset >50 mV, or open Hall connection; requires external pull-up |
| 17 | HALL4 | input | Connection to pin 4 of symmetrical InSb Hall element (AKM HW322/HW302) for Hall signal output; current limited to 10 mA maximum |
| 18 | HALL3 | output | Connection to pin 3 of symmetrical InSb Hall element (AKM HW322/HW302) for excitation return; provides regulated 0.6-0.95 V across HALL1-HALL3 dependent on GSEL mode |
| 19 | HALL2 | input | Connection to pin 2 of symmetrical InSb Hall element (AKM HW322/HW302) for Hall signal output with dynamic offset and 1/f noise cancellation via current spinning; current limited 10 mA |
| 20 | HALL1 | output | Connection to pin 1 of symmetrical InSb Hall element (AKM HW322/HW302) for excitation drive; provides regulated 0.6-0.95 V across HALL1-HALL3 dependent on GSEL mode |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
