Pinout

Pin Name Type Function
1 P3W passive Potentiometer 3 wiper terminal; its voltage must be between VSS and VDD and it can carry positive or negative current.
2 P3B passive Potentiometer 3 terminal B, the zero-scale connection for wiper value 0x00; its voltage must be between VSS and VDD and it can carry positive or negative current.
3 HVC/A0 input I2C address bit 0 latched at POR/BOR, and High Voltage Command pin when driven to VIHH; a high-voltage tolerant Schmitt-trigger input.
4 SCL input I2C serial clock input, which accepts only external clock signals as a slave; a high-voltage tolerant Schmitt-trigger input.
5 SDA bidirectional I2C serial data I/O implemented as an open-drain N-channel driver; a high-voltage tolerant Schmitt-trigger input.
6 VSS power_in Device ground reference.
7 P1B passive Potentiometer 1 terminal B, the zero-scale connection for wiper value 0x00; its voltage must be between VSS and VDD and it can carry positive or negative current.
8 P1W passive Potentiometer 1 wiper terminal; its voltage must be between VSS and VDD and it can carry positive or negative current.
9 P0W passive Potentiometer 0 wiper terminal; its voltage must be between VSS and VDD and it can carry positive or negative current.
10 P0B passive Potentiometer 0 terminal B, the zero-scale connection for wiper value 0x00; its voltage must be between VSS and VDD and it can carry positive or negative current.
11 A1 input I2C address bit 1 input that, together with A0, completes the device address; a high-voltage tolerant Schmitt-trigger input.
12 VDD power_in Positive power supply input relative to VSS; electrical performance may not meet data sheet specifications while VDD is below 2.7V.
13 P2B passive Potentiometer 2 terminal B, the zero-scale connection for wiper value 0x00; its voltage must be between VSS and VDD and it can carry positive or negative current.
14 P2W passive Potentiometer 2 wiper terminal; its voltage must be between VSS and VDD and it can carry positive or negative current.
