What are the key features of MCP4162-103E/SN?
- 256-step resolution over a 10 kOhm end-to-end resistance range with non-volatile EEPROM wiper position memory retaining settings through power cycles
- SPI interface at up to 10 MHz clock enabling fast host microcontroller updates for dynamic gain or offset trimming in signal-conditioning circuits
- 1.8 V to 5.5 V wide supply range and low quiescent current under 1 µA in standby mode supporting battery-powered calibration and portable instruments
What is MCP4162-103E/SN used for?
The MCP4162 replaces mechanical trimmers in audio volume controls, LCD contrast adjustments, and sensor offset calibration circuits where a host MCU updates the 10 kOhm wiper position via 10 MHz SPI and the value survives power loss in EEPROM. Its single-supply operation from 1.8 V suits portable test equipment, hearing-aid amplifiers, and white-goods control panels that demand precise, repeatable resistance settings without re-trimming at each power-on. Industrial process control loops and programmable filter banks also rely on its 256 discrete steps for fine gain tuning across the full temperature range.

Frequently Asked Questions
How many resistance steps does the MCP4162 provide, and what resolution does that give over a 10 kOhm range?
The MCP4162 offers 256 wiper positions across a 10 kOhm end-to-end resistance, yielding a step size of approximately 39 Ohm per increment, which is sufficient for audio loudness control, LCD contrast trimming, and op-amp gain setting where a mechanical 10 kOhm potentiometer would otherwise be used.
Does the MCP4162 retain its wiper position after a power cycle, and how is the value stored?
Yes — the MCP4162 stores the current 8-bit wiper setting in on-chip EEPROM with at least 100,000 write-cycle endurance, so the last programmed resistance between 0 Ohm and 10 kOhm is restored at every power-on without requiring the host MCU to re-initialize the SPI interface or re-send a resistance code.
At what SPI clock speed can a microcontroller update the MCP4162 wiper during closed-loop control?
The MCP4162 SPI port operates at up to 10 MHz clock frequency, allowing a microcontroller to transfer a full 16-bit command frame in 1.6 µs, fast enough to update a 10 kOhm gain resistor inside a 1 kHz bandwidth control loop without introducing perceptible latency in audio or sensor signal paths.
For a compact calibration board, how small is the MCP4162 SOIC-8 footprint compared to a through-hole trimmer?
The SOIC-8 package is 4.9 mm x 3.9 mm with 1.27 mm pitch, occupying roughly 19 mm² of PCB area, versus a typical 3296-style through-hole trimmer that requires a 9.5 mm x 4.5 mm drilled footprint of 43 mm², making the MCP4162 more than 50% smaller for dense SMD calibration arrays.
In which supply voltage systems can the MCP4162 be used alongside 1.8 V or 3.3 V microcontrollers?
The MCP4162 operates from 1.8 V to 5.5 V VDD, so it is directly compatible with 1.8 V ultra-low-power MSP430 and STM32L systems, 3.3 V ARM Cortex-M boards, and legacy 5 V PIC designs, all without a level-shifting circuit, provided the analog signal through the 10 kOhm wiper remains within the VDD-VSS window.
