HX717 from Avia Semicon Xiamen, in a SOP-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 | AVDD | power_in | Analog power supply input, 2.7 V to 5.5 V; it also supplies the internal regulator, and VRO must be set at least 200 mV below AVDD. |
| 2 | AGND | power_in | Analog ground input. |
| 3 | VRO/VREF | power_out | Regulator output for the external sensor supply and ADC reference input, set between 1.8 V and AVDD through the external divider where VRO = 1.11×(R1+R2)/R2. |
| 4 | VFB | input | Control input for the regulator feedback divider; it must be tied to AVDD when the internal regulator is not used. |
| 5 | AGND | power_in | Analog ground input. |
| 6 | S0 | input | Output data rate control bit 0, which together with S1 selects 10, 20, 80 or 320 Hz. |
| 7 | INNA | input | Channel A differential negative signal input. |
| 8 | INPA | input | Channel A differential positive signal input. |
| 9 | INNB | input | Channel B differential negative signal input. |
| 10 | INPB | input | Channel B differential positive signal input. |
| 11 | PD_SCK | input | Power-down control (active high; holding high for more than 80 µs powers the chip down) and serial clock input that shifts out data and selects the next channel and gain. |
| 12 | DOUT | output | Serial data output; it stays high while a conversion is not ready and goes low when 24-bit data is available. |
| 13 | S1 | input | Output data rate control bit 1; S1S0 = 00 gives 10 Hz, 01 gives 20 Hz, 10 gives 80 Hz and 11 gives 320 Hz. |
| 14 | XI | input | External clock input; when set to 0 the on-chip oscillator is used. |
| 15 | DGND | power_in | Digital ground input. |
| 16 | DVDD | power_in | Digital power supply input, 2.7 V to 5.5 V, which must be less than or equal to AVDD. |
