- 256-position resolution over a 50 kΩ end-to-end resistance providing approximately 195 Ω per step for fine adjustment
- I2C increment/decrement control interface enabling simple two-wire digital resistance adjustment from any microcontroller
- 2.7 V to 5.5 V single-supply operation in compact 8-pin MSOP for portable and battery-powered calibration circuits
Applications
The MCP4562-503E/MS serves as a digitally programmable gain or bias element in precision analog circuits where the resistance setting must survive power interruptions, such as factory-calibrated sensor offsets in industrial transmitters and medical monitoring devices. Its I2C interface allows a microcontroller to trim gain, set reference voltages, or adjust filter cut-off frequencies under firmware control without mechanical potentiometers. It is widely used in audio volume controls, programmable current sources, and LCD display contrast adjustment where non-volatile position storage eliminates the need for re-calibration at every power-up.

Frequently Asked Questions
How does the non-volatile memory in MCP4562-503E/MS differ from volatile digital potentiometers, and when is it essential?
The MCP4562-503E/MS stores its 256-position wiper setting in internal EEPROM, retaining the value indefinitely through power loss. A volatile potentiometer such as MCP4132 resets to mid-scale or its POR default at every power cycle, requiring the host MCU to restore the setting from external memory after boot. The non-volatile variant is essential in factory-calibrated systems — sensor transmitters, precision references, and analog trimmers — where the calibrated resistance value must survive field power interruptions without software intervention.
What resistance resolution does MCP4562-503E/MS provide, and is 256 steps sufficient for a 1% trim accuracy requirement?
With 256 positions over a 50 kΩ end-to-end resistance, each step is approximately 195 Ω (50 kΩ / 256). As a fraction of full scale, one step equals 0.39%, so a 1% trim accuracy requirement (±0.5%) spans about ±1.3 steps. For most analog trim applications — gain adjust, offset null, or filter pole tuning — 256 steps provides sufficient granularity, but critical precision circuits requiring sub-0.1% adjustment should use a narrower end-to-end resistance variant.
How does MCP4562-503E/MS behave as a voltage divider for a DAC reference voltage adjustment?
Connected as a voltage divider with the high terminal at VREF and the low terminal at ground, each of the 256 steps changes the wiper voltage by VREF/256. For a 2.048 V reference, one step equals 8 mV (2048 mV / 256), which is equivalent to the LSB size of an 8-bit DAC. The non-volatile position ensures the trimmed reference voltage is restored on power-up, making the MCP4562-503E/MS suitable for one-time factory calibration of precision voltage references in data acquisition systems.
What is the bandwidth of MCP4562-503E/MS, and does it limit use in audio signal path applications?
The MCP4562-503E/MS is specified with a nominal -3 dB bandwidth of approximately 200 Hz in the rheostat configuration with 50 kΩ resistance. This low bandwidth, caused by the RC product of the 50 kΩ resistance and the wiper parasitic capacitance of about 45 pF, restricts use to DC and very-low-frequency applications such as bias adjustment and calibration trim. For audio volume control requiring flat response to 20 kHz, a lower-resistance variant (5 kΩ) or a dedicated audio-grade digital potentiometer should be selected instead.
