**SGMICRO** · Operational Amplifier · QFN-10(1.4x1.8)

SGM7222YWQ10 from SGMICRO, in a QFN-10(1.4x1.8). 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 | HSD1+ | passive | Analog switch port HSD1+ of the DPDT switch, with analog I/O range 0 V to V+ and continuous/peak current limits of ±100 mA / ±150 mA for HSDn or Dn. |
| 2 | HSD2+ | passive | Analog switch port HSD2+ of the DPDT switch, with analog I/O range 0 V to V+ and continuous/peak current limits of ±100 mA / ±150 mA for HSDn or Dn. |
| 3 | D+ | passive | USB D+ data port of the switch, with analog I/O range 0 V to V+ and continuous/peak current limits of ±100 mA / ±150 mA for HSDn or Dn. |
| 4 | GND | power_in | Ground reference for the device (0 V). |
| 5 | D- | passive | USB D- data port of the switch, with analog I/O range 0 V to V+ and continuous/peak current limits of ±100 mA / ±150 mA for HSDn or Dn. |
| 6 | HSD2- | passive | Analog switch port HSD2- of the DPDT switch, with analog I/O range 0 V to V+ and continuous/peak current limits of ±100 mA / ±150 mA for HSDn or Dn. |
| 7 | HSD1- | passive | Analog switch port HSD1- of the DPDT switch, with analog I/O range 0 V to V+ and continuous/peak current limits of ±100 mA / ±150 mA for HSDn or Dn. |
| 8 | OE | input | Enable control pin; logic high (VIH min 1.6 V) turns both switch paths OFF, and logic low is VIL max 0.5 V. |
| 9 | V+ | power_in | Positive power supply, specified 1.8 V to 4.3 V with an absolute maximum of 4.6 V to GND. |
| 10 | S | input | Select input that chooses between the HSD1± and HSD2± channels when OE is low, with VIH min 1.6 V and VIL max 0.5 V. |
