Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | INDEP | input | Linear gain setting mode at power-up: each string resistor is loaded independently from its associated memory location, and once enabled it cannot be disabled by software. |
| 2 | RESET | input | Active-low hardware reset that refreshes the RDAC registers from EEPROM; tie to VLOGIC if the pin is not used. |
| 3 | GND | power_in | Ground pin serving as the logic ground reference. |
| 4 | A1 | passive | Terminal A of RDAC1, with VSS ≤ VA ≤ VDD. |
| 5 | W1 | passive | Wiper terminal of RDAC1, with VSS ≤ VW ≤ VDD. |
| 6 | B1 | passive | Terminal B of RDAC1, with VSS ≤ VB ≤ VDD. |
| 7 | VSS | power_in | Negative power supply; decouple with 0.1 µF ceramic and 10 µF capacitors. |
| 8 | A2 | passive | Terminal A of RDAC2, with VSS ≤ VA ≤ VDD. |
| 9 | W2 | passive | Wiper terminal of RDAC2, with VSS ≤ VW ≤ VDD. |
| 10 | B2 | passive | Terminal B of RDAC2, with VSS ≤ VB ≤ VDD. |
| 11 | VDD | power_in | Positive power supply; decouple with 0.1 µF ceramic and 10 µF capacitors. |
| 12 | VLOGIC | power_in | Logic power supply from 1.8 V to VDD; decouple with 0.1 µF ceramic and 10 µF capacitors. |
| 13 | SCLK | input | Serial clock line; data is clocked in on the logic low transition. |
| 14 | SDI | input | Serial data input. |
| 15 | SDO | output | Serial data output; open-drain, so it requires an external pull-up resistor. |
| 16 | SYNC | input | Active-low synchronization input; data is loaded into the input shift register when SYNC returns high. |
