Product details
Overview
MCP4013T-503E/CH from Microchip Technology is a volatile 6-bit digital potentiometer in SOT-23-6 package, configured as a 3-terminal potentiometer with 64-step resolution and 50 kΩ nominal resistance. It operates from 1.8V to 5.5V, features 75 Ω typical wiper resistance, 10 ppm/°C ratiometric tempco, and supports up/down serial interface for analog gain/offset trimming in sensor signal conditioning circuits.
For engineers reviewing the MCP4013T-503E/CH datasheet, MCP4013T-503E/CH pinout, MCP4013T-503E/CH application, or MCP4013T-503E/CH equivalent, key selection criteria include its 50 kΩ resistance value, SOT-23-6 footprint compatibility, ±0.5 LSb INL/DNL accuracy at 25°C, 200 kHz bandwidth, and high-voltage tolerant U/D inputs (up to 12.5 V) enabling direct interfacing with legacy logic families.
Technical Context
The MCP4013T-503E/CH implements a resistor ladder architecture with volatile RAM-based wiper control, where the wiper position is set via asynchronous up/down pulses on the U/D pin synchronized by CS. Its potentiometer configuration requires external connection of terminals A, W, and B - with no internal switching - and supports both voltage-divider and variable-resistor (rheostat) modes depending on terminal biasing.
Power-on reset defaults the wiper to mid-scale (code 1Fh), and device operation is validated across –40°C to +125°C with analog resistor characteristics specified only from 2.7V to 5.5V. The 50 kΩ variant exhibits 200 kHz –3 dB bandwidth and 10 µs typical wiper settling time under 100 pF load, directly tied to its higher resistance value and associated RC time constant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Resistance | 50 kΩ ±20% - defines full-scale analog range for gain/attenuation scaling in feedback networks |
| Resolution | 64 taps (6-bit) - provides 1.56% step granularity for fine analog adjustment |

FAQ
What is the nominal resistance value of the MCP4013T-503E/CH?
The MCP4013T-503E/CH has a nominal resistance of 50 kΩ, with a tolerance of ±20% across the A–B terminals. This value is confirmed in the Electrical Characteristics table of DS20001978D, where the "–503" suffix explicitly denotes the 50 kΩ variant. The resistance remains stable across the full operating temperature range when powered within 2.7V to 5.5V.
Does the MCP4013T-503E/CH retain its wiper setting after power cycling?
No, the MCP4013T-503E/CH uses volatile RAM for wiper storage and resets to mid-scale (code 1Fh) on power-up. This behavior is documented in the Features section and Electrical Specifications table of DS20001978D. For nonvolatile retention, Microchip offers the MCP41xx series with EEPROM, but the MCP4013T-503E/CH itself does not support persistent wiper settings.
What is the maximum operating frequency of the U/D interface for the MCP4013T-503E/CH?
The MCP4013T-503E/CH supports an Up/Down toggle frequency of up to 1 MHz, as specified in the SERIAL TIMING CHARACTERISTICS table of DS20001978D. This allows rapid wiper adjustment - for example, full 64-step traversal in under 64 µs - while maintaining reliable edge detection across the full –40°C to +125°C temperature range.
Can the MCP4013T-503E/CH be used in rheostat mode?
Yes, the MCP4013T-503E/CH can operate in rheostat mode by leaving either terminal A or B unconnected (floating), as noted in Footnote 1 of DS20001978D. In this configuration, the device functions as a two-terminal variable resistor between W and the connected terminal, retaining its 64-step resolution and 50 kΩ end-to-end resistance specification.
What is the wiper settling time for the MCP4013T-503E/CH at 50 kΩ?
The MCP4013T-503E/CH exhibits a typical wiper settling time of 10 µs for the 50 kΩ variant with a 100 pF capacitive load, as specified in the AC/DC CHARACTERISTICS table under "Wiper Settling Time". This value increases with load capacitance and decreases at lower resistance values (e.g., 0.5 µs for 2.1 kΩ), reflecting the RC-limited response of the internal resistor array.
