STRUCT MCP4725_PLATFORM_DATA(9)

🌸 struct mcp4725_platform_data(9) 🌸

okay bestie, welcome to the Kernel API Manual — yes we're in that part of the kernel, the part where a DAC gets its own little struct and honestly? iconic. this page is about struct mcp4725_platform_data, no cap 💅

---

✨ NAME ✨

struct mcp4725_platform_data — MCP4725/6 DAC specific data 🎀 like, the little bundle of settings that tells the driver how you want your DAC to behave. she's small. she's specific. she slays.

---

🦋 SYNOPSIS 🦋

struct mcp4725_platform_data {
    bool use_vref;
    bool vref_buffered;
 };

two bools. that's the whole struct. lowkey elegant, highkey minimal 🫶

---

💖 Members 💖

• use_vref — whether an external reference voltage on the Vref pin should be used. and heads up: when you turn this on, an additional vref-supply must be specified. no supply, no vibe. 🧚
• vref_buffered — controls buffering of the external reference voltage. that's it, that's the whole job. she buffers. 🌈

---

🎀 Description 🎀

okay so here's the tea ☕ — the Vref related settings are available only on MCP4756 👑 so don't come for the other chips expecting vref magic, they simply don't have it.

want the full lore? go read Documentation/devicetree/bindings/iio/dac/microchip,mcp4725.yaml for more information. it's giving "the source of truth" fr fr 📜✨

⭐ SEE ALSO ⭐

• Kernel file ./include/linux/iio/dac/mcp4725.h — go peek, iykyk 💜

bestie reminder 🌸: use_vref without a vref-supply is a whole mess — the docs say it must be specified when used, so pls don't skip it 🙈

that's the page!! short, sweet, and fully documented — this one came from ./include/linux/iio/dac, dated October 2026, and it's out here doing main character energy in struct mcp47...latform_data(9). periodt 💅🎀🦋
