Key Features
- Quad-channel non-volatile digital potentiometer with 257-position resolution for precise resistance control
- 2-wire I2C serial interface with 100kΩ end-to-end resistance and 0.1 kHz bandwidth
- 14-pin TSSOP package with non-volatile memory retains wiper position after power cycling
Applications
The MCP4462-104E/ST is well-suited for programmable gain amplifiers, offset voltage adjustments, and signal conditioning circuits where precise resistance tuning is required. Its non-volatile memory makes it ideal for calibration systems, industrial control panels, and consumer electronics where the last set resistance value must be retained across power cycles. With 4 independent channels and an I2C interface, it simplifies designs requiring multiple independent analog adjustments in space-constrained PCB layouts.

Frequently Asked Questions
How many wiper positions does the MCP4462-104E/ST support, and what is the end-to-end resistance?
The MCP4462-104E/ST provides 257 wiper positions across a 100 kΩ end-to-end resistance, giving each step approximately 390 Ω of resolution. This fine granularity makes it suitable for precision analog tuning applications requiring tight resistance control.
Does the MCP4462-104E/ST retain its wiper settings after power is removed?
Yes, the MCP4462-104E/ST features non-volatile memory that retains all 4 channel wiper positions after power is removed. This eliminates the need for a microcontroller initialization sequence on startup, which is critical in industrial calibration and always-on sensor systems operating from 1.8 V to 5.5 V supply rails.
Which communication protocol does the MCP4462-104E/ST use, and how many devices can share the same bus?
The MCP4462-104E/ST uses a 2-wire I2C serial interface operating at standard 100 kHz and fast 400 kHz bus speeds. Multiple devices can share the same bus by configuring unique 7-bit addresses, supporting up to 8 devices per I2C segment, making it efficient for multi-channel boards with up to 32 independent potentiometer channels.
What package does the MCP4462-104E/ST use and what are the key physical dimensions?
The MCP4462-104E/ST is housed in a 14-pin TSSOP package measuring approximately 5 mm × 4.4 mm with 0.65 mm pin pitch. This compact footprint enables use in space-constrained PCB designs while maintaining 4 independent 100 kΩ potentiometer channels with full I2C control.
