Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GND | power_in | Ground / negative supply reference for the chip. |+| 2 | C1 | passive | Internal balance/reference capacitor connection. Connect a 4.7 nF NPO capacitor to GND close to the IC. |+| 3 | CSEL | passive | Sensitivity-adjust capacitor pin. Optional external capacitor from 0 to 100 pF sets touch sensitivity (smaller = more sensitive). May be omitted in most cases. |+| 4 | KEY1 | passive | Touch sensing input for channel 1. Connects to sensing pad through a 1 kΩ series resistor. |+| 5 | KEY2 | passive | Touch sensing input for channel 2. Connects to sensing pad through a 1 kΩ series resistor. |+| 6 | KEY3 | passive | Touch sensing input for channel 3. Connects to sensing pad through a 1 kΩ series resistor. |+| 7 | KEY4 | passive | Touch sensing input for channel 4. Connects to sensing pad through a 1 kΩ series resistor. |+| 8 | KEY5 | passive | Touch sensing input for channel 5. Connects to sensing pad through a 1 kΩ series resistor. |+| 9 | OUT5 | output | Channel-5 key output. Polarity/behavior depends on MD pin: MD=VDD direct active-high, MD=GND toggle (self-lock), MD=floating active-low open-drain (needs pull-up). IO sink current typ 30 mA / max 40 mA at VDD=5 V. |+| 10 | OUT4 | output | Channel-4 key output. Polarity/behavior depends on MD pin (see OUT5). IO sink current typ 30 mA / max 40 mA at VDD=5 V. |+| 11 | OUT3 | output | Channel-3 key output. Polarity/behavior depends on MD pin (see OUT5). IO sink current typ 30 mA / max 40 mA at VDD=5 V. |+| 12 | OUT2 | output | Channel-2 key output. Polarity/behavior depends on MD pin (see OUT5). IO sink current typ 30 mA / max 40 mA at VDD=5 V. |+| 13 | OUT1 | output | Channel-1 key output. When MD=VDD direct active-high; MD=GND toggle self-lock; MD=floating OUT1 stays direct active-high push-pull (unlike OUT2-OUT5 which are open-drain when MD is floating). |+| 14 | SLEEP | input | Sleep-mode select. Tie to VDD to enable auto-sleep (~80 s of no touch enters low-power mode, I_sleep ≈ 45 µA typ). Tie to GND to disable sleep and keep the chip always active. |+| 15 | MD | input | Output-mode select (3-level). MD=VDD: OUT1-OUT5 direct output, active-high. MD=GND: OUT1-OUT5 toggle (self-lock) output, initial low. MD=floating: OUT1 direct active-high push-pull, OUT2-OUT5 active-low open-drain (needs external pull-up). |+| 16 | VDD | power_in | Positive supply, 2.5 V to 5.5 V. Typical operating current 0.8 mA at 3.0 V, 1.6 mA at 5.0 V. Recommend 100 nF decoupling and a 20 Ω series filter resistor as shown in the typical application. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Sam wing |+| Package | SOP-16 |+| Category | Sensors |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `AI05SOP16L`++## CAD (KiCad official)++- Symbol: `AI05`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Sam wing datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588884259361214464) (6 pp, sha256 `4861a64d40a552e9`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
