AD5141WBCPZ10-RL7 from Analog Devices, in a LFCSP-16(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground pin, serves as the logic ground reference. |
| 2 | A | passive | Terminal A of the RDAC, with VSS ≤ VA ≤ VDD. |
| 3 | W | passive | Wiper terminal of the RDAC, with VSS ≤ VW ≤ VDD. |
| 4 | B | passive | Terminal B of the RDAC, with VSS ≤ VB ≤ VDD. |
| 5 | VSS | power_in | Negative power supply; decouple with 0.1 µF ceramic and 10 µF capacitors. |
| 6 | SYNC/ADDR0 | input | Programmable address ADDR0 for multiple package decoding when DIS = 1; active-low synchronization data input when DIS = 0, where data loads into the RDAC register on SYNC returning high. |
| 7 | RESET | input | Hardware reset that refreshes the RDAC registers from EEPROM, activated at logic low; tie to VLOGIC if unused. |
| 8 | DIS | input | Digital interface select, selecting SPI when tied to GND (DIS = 0) and I2C when tied to VLOGIC (DIS = 1); this pin cannot be left floating. |
| 9 | VDD | power_in | Positive power supply; decouple with 0.1 µF ceramic and 10 µF capacitors. |
| 10 | VLOGIC | power_in | Logic power supply from 1.8 V to VDD; decouple with 0.1 µF ceramic and 10 µF capacitors. |
| 11 | SCLK/SCL | input | SPI serial clock (SCLK) or I2C serial clock (SCL), with data clocked in at logic low transition. |
| 12 | SDI/SDA | bidirectional | Serial data input (SDI) when DIS = 0 and serial data input/output (SDA) when DIS = 1. |
| 13 | WP | input | Optional write protect, active at logic low, that prevents changes to RDAC and EEPROM contents except when reloading EEPROM into the RDAC register; tie to VLOGIC if unused. |
| 14 | SDO/ADDR1 | output | Programmable address ADDR1 for multiple package decoding when DIS = 1; open-drain serial data output requiring an external pull-up resistor when DIS = 0. |
| 15 | INDEP | input | Linear gain setting mode at power-up, loading each string resistor from its associated memory location; once enabled it cannot be disabled by software. |
| 16 | LRDAC | input | Load RDAC, activated low, transferring the input register contents to the RDAC register for asynchronous update; tie to VLOGIC if unused. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
