What are the key features of MCP4023T-502E/CH?
- Nonvolatile 64-position linear digital potentiometer with 5 kΩ end-to-end resistance, retaining wiper setting through power cycles without host intervention
- Simple 2-wire increment/decrement serial interface requiring only 2 control pins, ideal for microcontrollers with limited I/O
- Tiny SOT-23-6 package measuring approximately 2.9 mm x 1.6 mm, enabling ultra-compact PCB layouts in space-constrained portable designs
What is MCP4023T-502E/CH used for?
The MCP4023T-502E/CH is used in audio volume control, LCD contrast adjustment, and gain-setting circuits where a compact, nonvolatile resistance adjustment is needed without mechanical wear. Its 2-wire interface simplifies firmware integration in battery-powered devices such as wearables and IoT sensor nodes that require persistent calibration offsets across power cycles. The 5 kΩ resistance and 64-step resolution also suit precision analog tuning in instrumentation front-ends.

Frequently Asked Questions
How does the nonvolatile memory in MCP4023T-502E/CH benefit battery-powered sensor calibration designs?
Because the MCP4023T-502E/CH stores the wiper position in nonvolatile memory, a calibrated gain or offset setting at 5 kΩ total resistance across 64 steps is retained even after power is removed. This eliminates the need for a microcontroller to re-send calibration data on every startup, reducing boot time by tens of milliseconds and saving firmware complexity in constrained 8-bit MCU designs.
What bandwidth limitation should designers consider when using MCP4023T-502E/CH in audio signal paths?
The MCP4023T-502E/CH has a nominal bandwidth of 2 kHz, which is sufficient for low-frequency control signals but limits its use to sub-audio or DC control applications rather than full-range 20 Hz to 20 kHz audio. For audio volume control above 2 kHz, a higher-bandwidth digital potentiometer such as the MCP4151 (1 MHz bandwidth) should be selected instead.
How many wiper steps does MCP4023T-502E/CH provide, and what resistance increment does each step represent?
The device provides 64 wiper positions over a 5 kΩ end-to-end resistance, yielding a step size of approximately 78 Ω per increment. This granularity is adequate for gain trimming and bias adjustment where better than 2% resolution is acceptable, but designs requiring finer 256-step resolution should consider the MCP4231 or MCP4261 with the same 5 kΩ variant.
Can MCP4023T-502E/CH be driven directly from a 3.3 V microcontroller GPIO without a level shifter?
Yes. The MCP4023T-502E/CH supports a supply voltage range of 1.8 V to 5.5 V, so a 3.3 V microcontroller GPIO meets its logic-high threshold and no level shifter is required. The 2-wire increment/decrement interface uses only 2 pins, simplifying connection to any MCU with spare digital outputs and reducing BOM by eliminating external translation components.
