Applications
The MCP4462T-502E/ST is used in multi-channel audio equalizers, programmable filter banks, and multi-axis sensor calibration circuits where 4 independently adjustable resistances with power-off retention are needed in a single package. Its I2C interface makes it easy to daisy-chain multiple devices on a shared bus for systems requiring more than 4 channels. It is also applied in programmable power supply reference voltage adjustment, LCD contrast control for multi-display panels, and fine-tuning analog signal chains in test and measurement instruments.

Frequently Asked Questions
How many wiper positions and what resistance resolution does each channel of MCP4462T-502E/ST offer?
Each of the 4 channels in MCP4462T-502E/ST provides 256 wiper positions across a 5 kΩ end-to-end resistance, giving approximately 19.5 Ω per step. This 8-bit resolution is adequate for audio volume control, gain trimming, and sensor offset calibration at 2 kHz nominal bandwidth.
Does MCP4462T-502E/ST remember its wiper settings when power is removed from the system?
Yes. All 4 channels include non-volatile memory that automatically stores the last wiper position programmed over I2C, ensuring the device restores its settings without microcontroller intervention at next power-up, which simplifies firmware in calibration-critical designs.
For a 4-channel programmable filter design, how does MCP4462T-502E/ST reduce BOM complexity compared to discrete solutions?
By integrating 4 independent 5 kΩ digital potentiometers with I2C control into a single 14-pin TSSOP, MCP4462T-502E/ST replaces 4 discrete potentiometers plus their decode logic, cutting BOM line items and reducing PCB area significantly versus separate single-channel ICs.
What is the supply chain lead time for MCP4462T-502E/ST and how should buyers plan for it?
MCP4462T-502E/ST has a factory lead time of 20 weeks, one of the longer lead times in the Microchip digital potentiometer family. Procurement teams designing it into production hardware should maintain at least 5 to 6 months of safety stock or place blanket orders to avoid line stoppages.
