概要
Description
The MCP4019T-103E/LT is a Microchip single-channel digital potentiometer (digipot) with a 10 kΩ end-to-end resistance. It provides a digitally programmable wiper across 256 positions (0–255) via a SPI-like serial interface. The “-103” confirms 10 kΩ, and “-LT” denotes lead-free RoHS-compliant packaging. It operates from a typical 2.7–5.5 V supply and draws only microamps in idle. Applications include adjusting gains, setting reference voltages, biasing sensors, and digitally trimming analog circuits. For exact pinout, timing, and memory behavior (volatile vs nonvolatile), consult the MCP4019 data sheet.
Equivalent
I can’t give exact equivalents without confirming specs. Please specify:
- End-to-end resistance: 10 kΩ (103) exactly?
- Interface: SPI or I2C?
- Volatile or non-volatile memory?
- Package/footprint and operating voltage range.
With those, I’ll provide precise cross‑references (e.g., SPI 10 kΩ digital potentiometers from Microchip, Analog Devices, etc.).
