AI04 from Sam wing, in a SOP-14. 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 | Power ground (电源地). Reference 0V for the device. |
| 2 | C1 | passive | Internal reference/balance capacitor connection (内部基准电容). Connect a 4.7nF capacitor to GND (range 1nF-10nF). Use NPO 10% dielectric placed close to the IC. |
| 3 | CSEL | passive | Sensitivity-adjust capacitor connection (灵敏度调节电容接口). Connect 0-100pF to GND; smaller value increases sensitivity, larger value increases noise immunity. Typically left floating (0pF) but a placeholder pad is recommended. |
| 4 | KEY1 | input | Capacitive touch sensing input for channel 1 (触摸按键/感应天线). Connect through a 1kΩ series resistor to the touch pad. Sensed capacitance range 0.2-200pF. |
| 5 | KEY2 | input | Capacitive touch sensing input for channel 2. Connect through a 1kΩ series resistor to the touch pad. |
| 6 | KEY3 | input | Capacitive touch sensing input for channel 3. Connect through a 1kΩ series resistor to the touch pad. |
| 7 | KEY4 | input | Capacitive touch sensing input for channel 4. Connect through a 1kΩ series resistor to the touch pad. |
| 8 | OUT4 | output | Channel 4 key output (通道4输出口). Output polarity/mode set by MD pin: direct active-high (MD=VDD), toggle/latched (MD=GND), or active-low open-drain requiring external pull-up (MD=floating). Sink current 30-40mA at VDD=5V. |
| 9 | OUT3 | output | Channel 3 key output. Behavior determined by MD pin (direct / toggle / open-drain). |
| 10 | OUT2 | output | Channel 2 key output. Behavior determined by MD pin (direct / toggle / open-drain). |
| 11 | OUT1 | output | Channel 1 key output. Behavior determined by MD pin (direct / toggle / open-drain). |
| 12 | SLEEP | input | Sleep mode select (睡眠模式选择). Tie to VDD to enable auto-sleep after ~80s of inactivity (reduced current, wakes on touch). Tie to GND to keep chip always active. |
| 13 | MD | input | Output mode select (输出模式选择). MD=VDD → direct active-high push-pull output. MD=GND → toggle/self-lock output, initial low. MD=floating → active-low open-drain output requiring external pull-up. |
| 14 | VDD | power_in | Positive supply (正电源). Operating range 2.5-5.5V; absolute max 6.0V. Typical operating current 0.8mA at 3V / 1.6mA at 5V; sleep current 45µA at 3V / 90µA at 5V. Decouple with 100nF near the pin; a ~20Ω series resistor from the rail is recommended in the typical application. |
