Product details
Overview
MAX5417PETA+ from Maxim Integrated is a 256-tap, nonvolatile, I²C-interface digital potentiometer with 50kΩ end-to-end resistance, 35ppm/°C end-to-end temperature coefficient, and ±0.5 LSB INL/DNL in voltage-divider mode. It replaces mechanical potentiometers in precision gain-setting, LCD contrast control, and programmable filter circuits operating from +2.7V to +5.25V supply.
For engineers reviewing the MAX5417PETA+ datasheet, MAX5417PETA+ pinout, MAX5417PETA+ application, or MAX5417PETA+ equivalent, key selection criteria include its factory-preset I²C address (010111A0), 3mm × 3mm TDFN-EP package with exposed pad, power-on wiper recall from EEPROM, and 5ppm/°C ratiometric tempco for low-drift analog designs.
Technical Context
The MAX5417PETA+ integrates a 255-element resistor string with digitally controlled wiper positioning via an I²C-compatible 2-wire interface supporting up to 400kbps. Its internal nonvolatile EEPROM stores wiper position for automatic restoration at power-up within 10µs.
It operates as a three-terminal device (H, L, W) configurable in voltage-divider or variable-resistor modes, with wiper resistance specified at 325–675Ω and wiper capacitance at 10pF. The device supports eight unique I²C addresses via A0 pin and factory-programmed address bits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-End Resistance | 50kΩ - defines maximum adjustable resistance range for gain/offset tuning and bias networks |
| Tap Resolution | 256 taps - enables 0.39% step resolution for fine-grained analog control |
| INL / DNL | ±0.5 LSB - ensures monotonicity and predictable linearity in voltage-divider configurations |
| Tempco (End-to-End) | 35ppm/°C - guarantees stable resistance over -40°C to +85°C industrial temperature range |
| Tempco (Ratiometric) | 5ppm/°C - maintains precise voltage division ratio despite temperature drift |
| I²C Speed | 400kbps - supports fast reconfiguration without bus contention in multi-device systems |
| Supply Voltage | +2.7V to +5.25V - compatible with 3.3V and 5V logic domains and mixed-supply systems |
Pinout & Package
MAX5417PETA+ is housed in a RoHS-compliant 3mm × 3mm, 8-pin TDFN package with exposed pad (EP) internally connected to GND for thermal management. The package requires PCB land pattern per Maxim document 21-0137 and supports reflow soldering at +260°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Power supply input | Accepts +2.7V to +5.25V; requires local 0.1µF bypass capacitor to GND |
| SCL (Pin 2) | I²C clock input | Active-high synchronous clock; open-drain input requiring external pullup |
| SDA (Pin 3) | I²C bidirectional data line | Open-drain I/O; shares bus with other I²C devices; requires 4.7kΩ pullup |
| A0 (Pin 4) | Address select input | Configures LSB of I²C slave address (010111A0); ties to GND or VDD for dual addressing |
| GND (Pin 5) | Ground reference | Primary return path; EP must be soldered to large ground plane for thermal performance |
| L (Pin 6) | Low terminal | One end of resistor string; connects to system ground or negative reference in divider mode |
| W (Pin 7) | Wiper terminal | Adjustable tap point; unloaded output impedance ≤675Ω; 10pF capacitance |
| H (Pin 8) | High terminal | Other end of resistor string; connects to VDD or positive reference in divider mode |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5175BRMZ-50 | 256-tap, 50kΩ, SPI interface; 30ppm/°C tempco; 10ppm/°C ratiometric; 2.7V–5.5V supply | Lacks I²C compatibility; requires SPI host; higher ratiometric tempco reduces gain stability vs. MAX5417PETA+ | Select when SPI-native microcontrollers dominate the design and I²C bus loading is a concern |
| MCP45HV51-503E/MS | 256-tap, 50kΩ, I²C interface; 100ppm/°C end-to-end tempco; 20ppm/°C ratiometric; 4.5V–22V high-voltage operation | Higher tempco degrades precision gain accuracy; supports higher voltage rails unsuitable for 3.3V/5V systems | Select only for high-voltage bias applications where MAX5417PETA+'s 5.25V max rating is insufficient |

FAQ
What is the factory-default wiper position stored in MAX5417PETA+ nonvolatile memory?
The MAX5417PETA+ is programmed at the factory with the wiper set to midscale (tap position 128). Upon power-up, the device automatically loads this value from EEPROM into the volatile register, ensuring repeatable startup behavior without host initialization.
Does MAX5417PETA+ support standard I²C bus speeds including 100kHz and 400kHz?
Yes, MAX5417PETA+ is fully compliant with standard-mode (100kHz) and fast-mode (400kHz) I²C specifications. Its timing parameters-including tSU-STA (0.6µs), tHD-STA (0.6µs), and fSCL (400kHz max)-meet I²C bus requirements under all operating conditions from -40°C to +85°C.
Can MAX5417PETA+ operate with a 2.5V supply voltage?
No, MAX5417PETA+ has a minimum supply voltage of +2.7V per absolute maximum ratings and electrical characteristics tables. Operation below 2.7V is not guaranteed and may result in undefined wiper behavior or I²C communication failure.
How is the I²C address of MAX5417PETA+ determined, and what is its value?
The MAX5417PETA+ uses a 7-bit I²C slave address of 0101110 (0x2E) with the A0 pin tied high (per Ordering Information: 010111A0). This yields a full 8-bit address byte of 0x5C for write operations and 0x5D for read operations.
What is the maximum continuous current rating for the wiper terminal (W) of MAX5417PETA+?
The MAX5417PETA+ wiper terminal supports a maximum continuous current of ±1.3mA when used in variable-resistor mode. Exceeding this limit risks parametric shift or permanent damage, especially under sustained DC load conditions.
