MAX9926UAEE+T from ANALOG DEVICES INC./MAXIM INTEGRATED, in a QSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | INT_THRS1 | input | Internal Adaptive Threshold 1 mode configuration pin; with ZERO_EN it selects Mode A1, A2, B or C per the MAX9924/MAX9926 mode table. |
| 2 | EXT1 | input | External Reference Input 1 must be left unconnected in Modes A1 and A2 and driven with an external voltage in Modes B and C (Mode B: 1.5V to VCC - 1.1V at TA = +125°C; Mode C: 0.14V to VCC - 1.1V at TA = +125°C). |
| 3 | BIAS1 | input | Input Bias 1 connects to an external resistor-divider and is bypassed to ground with 0.1µF and 10µF capacitors; BIAS voltage range is 1.5V to VCC - 1.1V in Modes A1 and B at TA = +125°C. |
| 4 | COUT1 | output | Comparator Output 1 is open-drain and requires a 10kΩ pullup resistor from COUT1 to VPULLUP. |
| 5 | COUT2 | output | Comparator Output 2 is open-drain and requires a 10kΩ pullup resistor from COUT2 to VPULLUP. |
| 6 | BIAS2 | input | Input Bias 2 connects to an external resistor-divider and is bypassed to ground with 0.1µF and 10µF capacitors. |
| 7 | EXT2 | input | External Reference Input 2 must be left unconnected in Modes A1 and A2 and driven with an external voltage in Modes B and C. |
| 8 | INT_THRS2 | input | Internal Adaptive Threshold 2 is a mode configuration pin for channel 2. |
| 9 | IN2+ | input | Noninverting Input 2 of the channel 2 input operational amplifier, which is rail-to-rail with a guaranteed input voltage range of 0 to VCC for the operational amplifier devices; for the differential-amplifier devices, input range is -0.3V to VCC + 0.3V. |
| 10 | IN2- | input | Inverting Input 2 of the channel 2 input stage; input current is limited to ±40mA on IN+, IN-, IN_+, IN_- per the absolute maximum ratings. |
| 11 | GND | power_in | Ground reference (VGND = 0V in the test conditions). |
| 12 | DIRN | output | Rotational Direction Output (MAX9926 only) is open-drain, indicates rotation direction from COUT1 and COUT2 for quadrature sensors, and requires a pullup resistor to VPULLUP. |
| 13 | ZERO_EN | input | Zero-Crossing Enable is a mode configuration pin internally pulled up to VCC with a 10kΩ resistor. |
| 14 | VCC | power_in | Power supply with an operating range of 4.5V to 5.5V; absolute maximum VCC to GND is -0.3V to +6V. |
| 15 | IN1- | input | Input 1 terminal named IN1- in the pin table; the table labels it 'Noninverting Input 1', which conflicts with the IN1- name (see review_required). |
| 16 | IN1+ | input | Input 1 terminal named IN1+ in the pin table; the table labels it 'Inverting Input 1', which conflicts with the IN1+ name (see review_required). |
