Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VEXC | power_out | Bridge sensor excitation output with range 0 to VSA−0.5V at IEXC=5mA and short-circuit current of 50mA. |
| 2 | GNDA | power_in | Analog ground, must be same as GNDD. |
| 3 | VSA | power_in | Analog voltage supply ranging from 2.7V to 5.5V, within 200mV of VSD. |
| 4 | VIN1 | input | Signal input voltage 1 with linear range 0.2V to VSA−1.5V and input bias current 0.1 to 1.5nA. |
| 5 | VIN2 | input | Signal input voltage 2 with linear range 0.2V to VSA−1.5V and input bias current 0.1 to 1.5nA. |
| 6 | VFB | output | VOUT feedback pin for over/under-scale limit circuitry with output voltage range 0.1V to VSA−0.1V. |
| 7 | VOUT | output | Analog output voltage of conditioned sensor with range 0.05V to VSA−0.1V at load resistance RL=10kΩ. |
| 8 | VSJ | output | Output amplifier summing junction for compensation and external gain setting resistors when driving capacitive loads greater than 100pF. |
| 9 | TEST | input | Test/external controller mode pin; pull to GNDD for normal operation. |
| 10 | VSD | power_in | Digital voltage supply ranging from 2.7V to 5.5V, within 200mV of VSA. |
| 11 | GNDD | power_in | Digital ground, must be same as GNDA. |
| 12 | PRG | tri_state | Single-wire UART-compatible programming interface with bit rates 4.8kbps to 38.4kbps, open-drain output. |
| 13 | SCL | tri_state | Two-wire clock interface for calibration at 1kHz to 400kHz, open-drain output. |
| 14 | SDA | tri_state | Two-wire data interface for calibration at 1kHz to 400kHz, open-drain output. |
| 15 | TEMPIN | input | External temperature signal input with programmable gain of 1, 2, 4, or 8 and voltage range −0.2V to VSA+0.2V. |
| 16 | REFIN/REFOUT | bidirectional | Reference input/output pin with selectable internal reference 2.5V or 4.096V (drift ±10 or ±7ppm/°C) or external reference input. |
