What are the key features of MCP4262-502E/UN?
- Dual-channel 256-step digital potentiometer with 5 kOhm (502) end-to-end resistance in a single MSOP-10 package
- SPI increment/decrement interface with volatile and non-volatile wiper position storage for power-cycle retention
- 2 kHz -3 dB bandwidth supporting audio and signal conditioning applications with low distortion
- Single-supply operation from 1.8 V to 5.5 V with typical 75 nA shutdown current for battery-powered designs
What is MCP4262-502E/UN used for?
The MCP4262-502E/UN is used for programmable gain control in audio amplifiers, calibration trim circuits in precision measurement equipment, and brightness adjustment in LED driver stages. Its dual-channel configuration allows simultaneous control of two independent resistive dividers from a single SPI bus, saving microcontroller GPIO lines. The non-volatile wiper memory ensures set-point retention across power cycles in field-calibrated instruments.

Frequently Asked Questions
How many resistance steps does the MCP4262-502E/UN provide and what is its full-scale resistance?
The MCP4262-502E/UN provides 256 discrete wiper steps across a 5 kOhm (nominal) end-to-end resistance, giving a step resolution of approximately 19.6 Ohm per step. The wiper resistance is typically 75 Ohm, which should be accounted for in precision voltage divider calculations. This resolution suits fine-grained gain or bias trimming in analog signal chains.
Does the MCP4262-502E/UN retain its wiper position after power is removed?
Yes, the MCP4262-502E/UN features non-volatile EEPROM-backed wiper position storage, retaining the last programmed position across power cycles without microcontroller intervention. It supports up to 100,000 write cycles to non-volatile memory and offers a data retention period exceeding 40 years, making it suitable for factory-calibrated instruments that must recall settings on power-up.
What supply voltage range and package does the MCP4262-502E/UN use for space-constrained designs?
The MCP4262-502E/UN operates from a 1.8 V to 5.5 V supply, covering both 3.3 V and 5 V systems. It comes in a 10-pin MSOP package with a 0.5 mm pin pitch, occupying a PCB footprint of approximately 3 mm x 3 mm. This compact size suits handheld instruments, wearables, and portable calibration tools where board space is limited.
For an audio gain control circuit, how does the MCP4262-502E/UN's bandwidth compare to typical audio requirements?
The MCP4262-502E/UN has a -3 dB bandwidth of 2 kHz, which covers the most audible speech-frequency range but falls short of full 20 kHz hi-fi audio. It is well suited for voice-band audio controls, telephone interfaces, and low-frequency analog calibration loops operating below 1 kHz. For wider audio bandwidth, the MCP4162 series with higher resistance values may be evaluated as an alternative.
