**Texas Instruments** · Digital Potentiometers · WQFN-16-EP(3x3)

TPL0202-10MRTER from Texas Instruments, in a WQFN-16-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 | VDD | power_in | Power supply voltage; recommended VDD to GND range is 2.7 V to 5.5 V (absolute maximum VDD to GND is -0.3 V to 7 V). |
| 2 | SCLK | input | SPI serial clock input; the datasheet specifies a maximum SCLK frequency of 5 MHz and input levels of VIH 0.7 x VDD (2.7 V to 3.6 V supply) or 2.4 V (3.6 V to 5.5 V supply) and VIL 0 to 0.8 V. |
| 3 | DIN | input | SPI serial data input, using the same logic levels as SCLK (VIL max 0.8 V; VIH as specified for SCLK). |
| 4 | CS | input | SPI chip select, active low, using the same logic levels as SCLK and DIN. |
| 5 | N.C. | unconnected | Not internally connected; can be connected to GND. |
| 6 | N.C. | unconnected | Not internally connected; can be connected to GND. |
| 7 | GND | power_in | Ground reference; all voltages in the datasheet are referenced to ground. |
| 8 | N.C. | unconnected | Not internally connected; can be connected to GND. |
| 9 | N.C. | unconnected | Not internally connected; can be connected to GND. |
| 10 | LB | bidirectional | Low terminal of potentiometer B; terminal voltage range is 0 to VDD and wiper current is limited to ±2 mA. |
| 11 | WB | bidirectional | Wiper terminal of potentiometer B; wiper current is limited to ±2 mA (continuous, TPL0202-10). |
| 12 | HB | bidirectional | High terminal of potentiometer B; terminal voltage range is 0 to VDD. |
| 13 | LA | bidirectional | Low terminal of potentiometer A; terminal voltage range is 0 to VDD and wiper current is limited to ±2 mA. |
| 14 | WA | bidirectional | Wiper terminal of potentiometer A; wiper current is limited to ±2 mA (continuous, TPL0202-10). |
| 15 | HA | bidirectional | High terminal of potentiometer A; terminal voltage range is 0 to VDD. |
| 16 | N.C. | unconnected | Not internally connected; can be connected to GND. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
