Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | 5-V input supply with 4.7-µF external bypass capacitor required for stability of internal circuits. |
| 2 | GND | power_in | Ground connection to system ground rail. |
| 3 | Vref | power_in | Internally generated reference supply voltage with 22-nF external bypass capacitor for bias and noise decoupling. |
| 4 | OUT | output | Buffered analog integrator output for microprocessor A/D interface with 2.2-nF external stabilizing capacitor. |
| 5 | NC | unconnected | No connection; terminal reserved for test purposes only, not connected in system application. |
| 6 | NC | unconnected | No connection; terminal reserved for test purposes only, not connected in system application. |
| 7 | INT/HOLD | input | Integration/hold mode selection input (high for integrate, low for hold) with internal pulldown for default hold mode. |
| 8 | CS | input | Chip select for SPI communications, active low with internal pullup resistor for default inactive state. |
| 9 | XIN | input | Oscillator inverter input for external clock signal with 1-MΩ feedback resistor to XOUT for bias. |
| 10 | XOUT | output | Oscillator inverter output for external oscillator circuit with 1-MΩ feedback resistor to XIN. |
| 11 | SDO | tri_state | Serial data output for SPI bus with tri-state high-impedance mode when CS is pulled to VDD. |
| 12 | SDI | input | Serial data input for SPI with internal pullup to VDD and 8-bit word format data stream. |
| 13 | SCLK | input | SPI clock input with internal pullup resistor and data clocked into shift register on falling edge. |
| 14 | TEST | input | Test mode control input, active low with internal pullup to VDD (default inactive, leave open or tie high). |
| 15 | CH2P | input | Positive input for amplifier 2 interfacing to knock sensor with input range 0.05 to VDD-0.05 V. |
| 16 | CH2N | input | Negative input for amplifier 2 interfacing to knock sensor with input range 0.05 to VDD-0.05 V. |
| 17 | CH2FB | output | Feedback output of amplifier 2 for external gain-setting resistor connection with rail-to-rail compatibility. |
| 18 | CH1FB | output | Feedback output of amplifier 1 for external gain-setting resistor connection with rail-to-rail compatibility. |
| 19 | CH1N | input | Negative input for amplifier 1 interfacing to knock sensor with input range 0.05 to VDD-0.05 V. |
| 20 | CH1P | input | Positive input for amplifier 1 interfacing to knock sensor with input range 0.05 to VDD-0.05 V. |
