What are the key features of MCP4562-502E/MS?
- 256-step, 5 kOhm digital potentiometer with ~19.6 Ohm per step resolution for precise analog signal conditioning and gain adjustment
- Non-volatile EEPROM wiper memory retains the set resistance across power cycles, eliminating MCU-driven initialization on every startup
- I2C interface with increment/decrement and direct-write commands, allowing up to 8 devices on a single 2-wire bus via programmable address pins
- 2 kHz small-signal bandwidth enables use in audio signal paths and low-frequency filter tuning applications up to the audio band
- Compact MSOP-8 package operating from 1.8 V to 5.5 V with less than 1 µA standby current for space-constrained, battery-powered designs
What is MCP4562-502E/MS used for?
The MCP4562-502E/MS is well suited for audio amplifier gain control, sensor bridge offset trimming, and LCD bias adjustment where a 5 kOhm, 256-step digitally programmable resistance with 2 kHz bandwidth replaces a mechanical trimmer. Its I2C interface allows a single microcontroller to address multiple potentiometers on a shared 2-wire bus, simplifying board routing in multi-channel calibration systems. The non-volatile wiper storage and 1.8 V to 5.5 V supply range also make it practical for portable medical instruments and industrial process control modules that require power-cycle-persistent calibration settings.

Frequently Asked Questions
How fine is the resistance resolution of the MCP4562-502E/MS across its 256 steps?
With a 5 kOhm end-to-end resistance divided into 256 steps, each step changes the wiper resistance by approximately 19.6 Ohm. The wiper contact resistance is typically 75 Ohm, so the minimum settable resistance is about 75 Ohm when the wiper is at position 0. This 19.6 Ohm step size is finer than the 128-step, 100 kOhm variants and suits precision gain-setting networks in instrumentation amplifiers and active filter tuning circuits.
Does the MCP4562-502E/MS remember its wiper position after a power cycle, and how long does it retain the value?
Yes, the MCP4562 includes on-chip EEPROM that automatically saves the wiper position. The EEPROM is rated for 100,000 write cycles and retains data for over 40 years without power. This means a factory-programmed gain or offset trim survives board power-cycling, resets, and battery replacement without any MCU re-initialization routine, reducing firmware complexity in calibrated measurement products.
How many MCP4562-502E/MS devices can share a single I2C bus, and how are they addressed?
The MCP4562 supports up to 8 devices on a single I2C bus by combining a fixed 3-bit device code with 2 hardware address pins (A0, A1), giving 4 unique addresses for this variant. Additional bus expansion can be achieved with I2C multiplexers. The I2C interface supports standard 100 kHz and fast 400 kHz modes, allowing a microcontroller to update all 8 devices' 5 kOhm wiper positions within a few microseconds per transaction.
What is the signal bandwidth of the MCP4562-502E/MS and does it suit audio applications?
The MCP4562-502E/MS has a nominal small-signal bandwidth of 2 kHz, which covers the audible frequency range from 20 Hz to 2 kHz. For full audio bandwidth up to 20 kHz, the MCP4562 can be used in DC or very low frequency gain-setting positions in an amplifier feedback network rather than directly in the signal path. In bass-frequency filter tuning, volume control attenuator ladders, and low-frequency oscillator timing networks, the 2 kHz bandwidth is entirely adequate.
How does the MSOP-8 package of the MCP4562-502E/MS help reduce PCB area compared to SOIC alternatives?
The MSOP-8 package measures approximately 3 mm × 3 mm with a 0.65 mm pin pitch, roughly half the footprint of an equivalent SOIC-8 device at 3.9 mm × 4.9 mm. In dense portable or wearable PCB layouts where every square millimeter of board space saves cost, the MSOP-8 allows 5 kOhm digital potentiometer functionality in a minimal footprint. The package also has a lower profile suitable for thin consumer devices, while the 1.8 V to 5.5 V supply range keeps it compatible with modern low-voltage MCU platforms.
