Pin Functions
| PIN | TYPE(1) | DESCRIPTION | |
|---|---|---|---|
| NO. | NAME | ||
| 1 | SCL | I | I2C Clock input |
| 2 | SDA | I/O | I2C Data input/output |
| 3 | CLKIN | I | Master Clock input. Tie this pin to GND if internal oscillator is selected |
| 4 | ADDR | I | I2C Address selection pin: when ADDR=L, I2C address = 0x2A, when ADDR=H, I2C address = 0x2B. |
| 5 | INTB | O | Configurable Interrupt output pin |
| 6 | SD | I | Shutdown input |
| 7 | VDD | P | Power Supply |
| 8 | GND | G | Ground |
| 9 | IN0A | A | External LC sensor 0 connection |
| 10 | IN0B | A | External LC sensor 0 connection |
| 11 | IN1A | A | External LC sensor 1 connection |
| 12 | IN1B | A | External LC sensor 1 connection |
| 13 | IN2A | A | External LC sensor 2 connection (LDC1314 only) |
| 14 | IN2B | A | External LC sensor 2 connection (LDC1314 only) |
| 15 | IN3A | A | External LC sensor 3 connection (LDC1314 only) |
| 16 | IN3B | A | External LC sensor 3 connection (LDC1314 only) |
| DAP | DAP(2) | N/A | Connect to Ground |
(1) I = Input, O = Output, P=Power, G=Ground, A=Analog
(2) There is an internal electrical connection between the exposed Die Attach Pad (DAP) and the GND pin of the device. Although the DAP can be left floating, for best performance the DAP should be connected to the same potential as the device's GND pin. Do not use the DAP as the primary ground for the device. The device GND pin must always be connected to ground.
