Product details
Overview
MCP4013T-103E/CH from Microchip Technology is a volatile 6-bit digital potentiometer in SOT-23-6 package, configured as a 10 kΩ potentiometer with 64-step resolution, ±20% resistance tolerance, and mid-scale power-on wiper default (1Fh). It operates from 1.8V to 5.5V, supports up/down serial interface, and delivers 10 ppm ratiometric tempco for precision analog trimming in sensor signal conditioning circuits.
For engineers reviewing the MCP4013T-103E/CH datasheet, MCP4013T-103E/CH pinout, MCP4013T-103E/CH application, or MCP4013T-103E/CH equivalent, key selection criteria include its 10 kΩ nominal resistance, SOT-23-6 footprint compatibility, 75 Ω typical wiper resistance, 4 µA max static current at 2.7V, and support for high-voltage digital inputs up to 12.5V.
Technical Context
The MCP4013T-103E/CH implements a resistor ladder with volatile RAM-based wiper control, using a simple two-wire up/down protocol without clock or address lines. Its internal architecture includes power-up and brown-out logic that loads the factory-default 1Fh wiper position on reset.
It functions exclusively as a three-terminal potentiometer (A–W–B), not rheostat mode - unlike MCP4012/MCP4014 - and requires external pull-up/pull-down on CS for proper U/D sequencing. Wiper settling time is 2 µs (typ.) for 10 kΩ load with 100 pF capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Resistance | 10 kΩ ±20% - defines full-scale analog attenuation range between terminals A and B |
| Resolution | 64 taps (6-bit) - enables 15.625% incremental adjustment per step across full resistance range |
| Wiper Resistance | 75 Ω typ. - contributes minimal series offset in precision voltage divider configurations |
| Ratiometric Tempco | 10 ppm/°C typ. - ensures stable output ratio over temperature in potentiometer mode |
| Supply Current | 1 µA max (serial inactive) - enables ultra-low-power biasing in battery-operated sensor front-ends |
| Operating Voltage | 1.8V to 5.5V - supports direct interface with 1.8V logic and mixed-voltage systems |
| Digital Input Tolerance | Up to 12.5V - allows direct connection to higher-voltage control signals without level-shifting |
Pinout & Package
SOT-23-6 package: 2.9 mm × 1.6 mm × 1.1 mm body, gull-wing leads, JEDEC MO-178AC compliant. Thermal resistance θJA = 120°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (W) | Wiper Output | Adjustable tap point; delivers variable voltage/current based on 64-step setting |
| 3 (B) | Resistor Terminal B | Low-side end of resistive element; typically tied to ground or return path |
| 4 (CS) | Chip Select | Active-low enable for U/D commands; internal weak pull-up/pull-down (16 kΩ) |
| 5 (U/D) | Up/Down Control | Edge-triggered direction input: rising edge increments wiper, falling edge decrements |
| 6 (VDD) | Positive Supply | Power rail (1.8–5.5V); powers internal logic and resistor array bias circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Volatile wiper memory | RAM-based setting resets to 1Fh (mid-scale) on power-up - simplifies initialization in closed-loop calibration |
| Simple 2-wire interface | No clock, no data lines - reduces PCB routing complexity and eliminates timing setup/hold constraints |
| High-voltage tolerant inputs | CS and U/D accept up to 12.5V - enables direct drive from industrial PLC outputs or legacy microcontrollers |
| Low wiper resistance | 75 Ω typ. - minimizes gain error in op-amp feedback networks and improves linearity at low codes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP4013T-103E/MC | Same electrical specs; MSOP-8 package (3.0 × 3.0 mm), higher θJA (206°C/W) | Requires PCB redesign for larger footprint and different thermal profile | Select when board space permits larger package and enhanced thermal dissipation is needed |
| AD5160BRJZ-10-RL7 | 64-step, 10 kΩ, but uses SPI interface and has 125 Ω wiper resistance; ±30% RAB tolerance | Requires SPI controller resource and suffers higher gain error in precision feedback loops | Choose only if existing design already uses SPI peripherals and wiper resistance is not critical |
Compared with MCP4013T-103E/MC, the MSOP variant trades compactness for thermal margin; compared with AD5160BRJZ-10-RL7, the MCP4013T-103E/CH offers simpler control, lower wiper resistance, tighter resistance tolerance, and better ratiometric stability - making it preferable for analog-critical trimming where minimal component count and predictable linearity matter.

FAQ
What is the power-on wiper position for MCP4013T-103E/CH?
The MCP4013T-103E/CH defaults to wiper code 1Fh (31 decimal, mid-scale) on power-up. This is factory-programmed volatile RAM behavior and occurs regardless of prior state. No external programming is required to achieve this reset condition, and it applies consistently across all units of MCP4013T-103E/CH.
Can MCP4013T-103E/CH be used in rheostat mode?
No, MCP4013T-103E/CH is specified and tested exclusively as a potentiometer (three-terminal A–W–B device). Unlike MCP4012 or MCP4014, it lacks rheostat-mode characterization - its INL/DNL, tempco, and bandwidth specs apply only to potentiometer configuration. Using terminal A or B as open violates datasheet operating conditions.
What is the maximum allowable voltage across terminals A and B of MCP4013T-103E/CH?
The absolute maximum voltage between terminals A and B is limited by the device's absolute maximum rating: |VA – VB| ≤ VDD + 0.3V, with VDD ≤ 6.5V. For safe operation within specifications, the analog voltage across A–B must remain within VSS to VDD, and total power dissipation must stay below 100 mW to avoid exceeding θJA-limited junction temperature.
Does MCP4013T-103E/CH support 1.8V logic-level control signals?
Yes, MCP4013T-103E/CH fully supports 1.8V operation: VIH = 0.7×VDD and VIL = 0.3×VDD ensure reliable detection of U/D and CS edges at 1.8V supply. Its 1.8V–5.5V operating range and 1 µA static current make it suitable for ultra-low-power IoT sensor nodes powered by coin cells or energy harvesters.
How does the high-voltage input feature work on MCP4013T-103E/CH?
MCP4013T-103E/CH accepts up to 12.5V on CS and U/D pins independent of VDD, enabling direct interface with 5V/12V control systems. This is implemented via internal protection clamps and threshold-detect circuitry (VIHH = 8.5–12.5V), not level-shifting. The feature remains active even when VDD = 1.8V, allowing mixed-voltage system integration without external components.
