MAX5400EKA+T from Analog Devices Inc Maxim Integrated, in a SOT-23-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | L | passive | Low terminal of the internal 50kΩ resistor string. Absolute voltage must remain between -0.3V and (VDD + 0.3V); maximum continuous current ±1mA. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | CS | input | Active-low chip select input for the 3-wire SPI-compatible serial interface. When taken low, DIN data is clocked into the 8-bit shift register on SCLK rising edges; latching to the decoder occurs on the rising edge of CS. |
| 4 | DIN | input | Serial data input. MSB (D7) is shifted in first on each rising SCLK edge while CS is low. Logic thresholds are 0.7×VDD (VIH) and 0.3×VDD (VIL). |
| 5 | SCLK | input | Serial clock input. Minimum clock period 100ns (tCP); minimum high/low pulse widths 40ns. |
| 6 | VDD | power_in | Positive supply, +2.7V to +5.5V. Bypass with a 0.1µF capacitor to GND. Typical supply current 0.1µA at 2.7V, 0.7µA at 5V. |
| 7 | W | passive | Wiper terminal of the digital potentiometer. Selects 1 of 256 tap points along the H-to-L resistor string; wiper resistance typically 250Ω (max 800Ω). Maximum continuous current ±1mA. |
| 8 | H | passive | High terminal of the internal 50kΩ resistor string. Absolute voltage must remain between -0.3V and (VDD + 0.3V); maximum continuous current ±1mA. |
