Product details

50 kOhm linear-taper digital pot — 64 taps, volatile

The Microchip MCP4011T-503E/MS is a single-channel, 50 kOhm digital potentiometer with a linear taper and 64 wiper tap positions. The resistance is set via an Up/Down (U/D, CS) interface, and the wiper position is volatile — it resets to mid-scale on power-up and loses the setting when power is removed.

The supply voltage spans 1.8V to 5.5V, so it runs directly off a 3.3V or 5V rail without an extra regulator.

Housed in an 8-MSOP package (3.00 mm width, 0.118" pitch), surface-mount only. The supplier device package is 8-MSOP, consistent with the 8-TSSOP/MSOP footprint.

Listed as Active on the lifecycle status — no end-of-life or last-time-buy signal. ROHS3 compliant.

Frequently asked questions

Is MCP4011T-503E/MS a suitable replacement for MCP4011-503E/MS?

The MCP4011T-503E/MS and MCP4011-503E/MS share the same 50 kOhm resistance, linear taper, 64 taps, and 8-MSOP package. The 'T' suffix indicates Tape & Reel packaging — electrically and functionally identical. Yes, it is a drop-in replacement.

Can MCP4011T-503E/MS be used in audio volume control?

The 64-tap resolution and linear taper produce 64 discrete steps — that is coarse for audio volume control, where logarithmic taper and 128+ steps are typical. It works for basic level-setting but not for smooth volume adjustment.

Is MCP4011T-503E/MS compatible with 3.3V systems?

Yes. The supply voltage range of 1.8V to 5.5V includes 3.3V, so it operates directly on a 3.3V rail without a level shifter.
