LM8342SD from Texas Instruments, in a WSON-10-EP(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 | OUT | output | Current sink output adjustable in 128 steps; full scale current range 5 µA to 100 µA |
| 2 | AVDD | power_in | Analog reference voltage input for DAC; operating range 4.5 V to 18 V |
| 3 | WPN | input | Write protect input active low; high level enables EEPROM access; includes internal pull-down resistor |
| 4 | WPP | output | Write protect signal output; logical inverse of WPN input signal |
| 5 | GND | power_in | Ground reference connection |
| 6 | VDD | power_in | Digital supply voltage; operating range 2.25 V to 3.6 V (2.6 V to 3.6 V when AVDD exceeds 13 V) |
| 7 | SDA | bidirectional | I2C compatible serial data line; maximum bus speed 400 kHz; open-drain output requires external pull-up resistor |
| 8 | SCL | bidirectional | I2C compatible serial clock line; maximum bus speed 400 kHz; open-drain output requires external pull-up resistor |
| 9 | SCL-S | input | Switched SCL connection for in-circuit PCB testing; connected to SCL when WPN is high; alternative clock source |
| 10 | SET | input | Maximum output current adjustment pin; connects to external RSET resistor to set full-scale current; typical values 10 kΩ to 45 kΩ |
| 11 | DAP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
