- Wide supply voltage range of 1.8 V to 5.5 V supporting both 3.3 V and 5 V system architectures
Applications
The MCP4262-104E/UN is used in audio processing circuits requiring independent control of two analog parameters such as volume and tone from a single MSOP-10 package, reducing BOM count compared to two separate single-channel devices. Its 100 kΩ resistance and 256-step resolution make it suitable for precision offset and gain trimming in instrumentation amplifier circuits and active filter designs. The non-volatile memory and wide 1.8 V to 5.5 V operating range also suit battery-powered portable instruments where calibration constants must persist through power cycles.

Frequently Asked Questions
How does the MCP4262-104E/UN provide two independent analog adjustment channels, and what resolution does each channel offer?
The MCP4262-104E/UN contains 2 independent digital potentiometer channels, each with 256 wiper positions across a 100 kΩ end-to-end resistance, providing approximately 391 Ω per step. Both channels share the SPI bus and are individually addressable, allowing simultaneous independent control of two analog signals such as gain and offset in a single MSOP-10 package.
How does the 0.1 kHz nominal bandwidth of the MCP4262-104E/UN affect its suitability for different signal conditioning applications?
The 0.1 kHz (100 Hz) nominal bandwidth means the MCP4262-104E/UN accurately passes signals up to approximately 100 Hz through the resistive element, making it suitable for DC trimming, slow feedback loop control, and very low-frequency audio adjustments. For higher-frequency signal paths above 1 kHz, the bandwidth limitation attenuates the signal, so designers should consider higher-bandwidth alternatives for AC signal applications.
In a battery-powered portable instrument, what advantage does the non-volatile wiper memory of the MCP4262-104E/UN provide over a volatile digital potentiometer?
The non-volatile EEPROM in the MCP4262-104E/UN retains both channel wiper positions after power-down, so the instrument restarts with the same calibration offsets without any microcontroller initialization sequence. This eliminates a potential firmware failure mode at startup, reduces system wake-up time by several milliseconds, and ensures consistent measurement accuracy across battery replacement events in handheld instruments.
For a compact dual-axis servo bias circuit, how does the MSOP-10 package footprint of the MCP4262-104E/UN compare to using two separate SOIC-8 potentiometers?
The MSOP-10 package of the MCP4262-104E/UN measures approximately 3.0 mm × 4.9 mm (about 15 mm²), delivering 2 channels in roughly half the area of a single SOIC-8 device at around 30 mm². Replacing two SOIC-8 single-channel potentiometers with one MCP4262-104E/UN saves approximately 45 mm² of PCB area and reduces solder joint count from 16 to 10 pads.
