**Texas Instruments** · Proximity Sensors · TSSOP-16

LDC3114QPWRQ1 from Texas Instruments, in a TSSOP-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 | COM | passive | Common return current path for all LC resonator sensors; a capacitor should be connected from this pin to GND (see Setting COM Pin Capacitor). |
| 2 | GND | power_in | Ground; both GND pins should be connected to the system ground on the PCB. |
| 3 | LPWRB | input | Normal/Low Power Mode select: set to VDD for Normal Power Mode or to ground for Low Power Mode. |
| 4 | VDD | power_in | Power supply; recommended operating range is 1.71 V to 1.89 V, with an absolute maximum of 2.2 V. |
| 5 | INTB | output | Interrupt output whose polarity can be configured in Register 0x11; SCL, SDA and INTB are rated to 3.6 V absolute maximum. |
| 6 | IN3 | passive | Channel 3 LC sensor input (analog). |
| 7 | IN2 | passive | Channel 2 LC sensor input (analog). |
| 8 | IN1 | passive | Channel 1 LC sensor input (analog). |
| 9 | IN0 | passive | Channel 0 LC sensor input (analog). |
| 10 | GND | power_in | Ground; both GND pins should be connected to the system ground on the PCB. |
| 11 | OUT3 | output | Channel 3 logic output whose polarity can be configured in Register 0x1C. |
| 12 | OUT2 | output | Channel 2 logic output whose polarity can be configured in Register 0x1C. |
| 13 | OUT1 | output | Channel 1 logic output whose polarity can be configured in Register 0x1C. |
| 14 | SDA | bidirectional | I2C data line; the I2C address is 0x2A. SDA is rated to 3.6 V absolute maximum. |
| 15 | OUT0 | output | Channel 0 logic output whose polarity can be configured in Register 0x1C. |
| 16 | SCL | input | I2C clock input; SCL is rated to 3.6 V absolute maximum. |
