Product details
Overview
DS4301Z-200 from Maxim Integrated is a single-channel, 32-position nonvolatile digital potentiometer with 200kΩ end-to-end resistance, 2.4V–5.5V supply range, and EEPROM wiper storage. It functions as an adjustable voltage divider in analog control loops, enabling precise white LED backlight brightness tuning in portable battery-powered systems.
For engineers reviewing the DS4301Z-200 datasheet, DS4301Z-200 pinout, DS4301Z-200 application, or DS4301Z-200 equivalent, key selection considerations include its three-terminal increment/decrement interface, industrial temperature operation (–40°C to +85°C), µSOP-8 package footprint, and guaranteed 50,000 EEPROM write cycles.
Technical Context
The DS4301Z-200 implements a 5-bit wiper register controlled via asynchronous CS/U/D/INC logic, with no clock or serial protocol required. Its analog resistor network features ±0.5 LSB absolute linearity and ±20% end-to-end resistance tolerance at +25°C.
Wiper position is loaded from EEPROM within 500µs after VCC stabilizes ≥2.4V; storage to EEPROM requires a 10ms command-initiated write cycle. The device draws ≤60µA standby current at 5V and supports ±1mA wiper current without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-End Resistance | 200kΩ ±20% at +25°C - sets full-scale adjustment range for voltage divider applications |
| Wiper Positions | 32 linear steps - enables discrete but stable brightness or gain control with 3.125% resolution per step |
| Supply Voltage Range | 2.4V to 5.5V - compatible with single-cell Li-ion, 3.3V, and 5V rails in portable electronics |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded and handheld environments |
| EEPROM Endurance | 50,000 write cycles - supports field calibration and infrequent reconfiguration over product lifetime |
| Wiper Storage Time | 10ms - defines minimum interval between wiper adjustments requiring nonvolatile save |
| Standby Current | 15µA (typ) at 3V - minimizes quiescent drain in always-on backlight control circuits |
Pinout & Package
DS4301Z-200 is housed in an 8-pin µSOP (118 mil) package, measuring 3.0mm × 3.0mm × 1.0mm, optimized for space-constrained portable PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 INC | Increment/Decrement Control | Edge-triggered input: high-to-low transition moves wiper per U/D state; requires tDI setup before edge |
| 2 U/D | Direction Control | Static logic level: high = increment, low = decrement; must be stable >100ns before INC edge |
| 3 H | Potentiometer High Terminal | Analog node connected to VCC or reference voltage; forms top of resistive ladder |
| 4 GND | Ground Reference | Return path for analog and digital circuitry; must be low-impedance for linearity stability |
| 5 W | Wiper Terminal | Adjustable tap point; delivers intermediate voltage proportional to position; supports ±1mA load |
| 6 L | Potentiometer Low Terminal | Analog node tied to GND or bias point; forms bottom of resistive ladder |
| 7 CS | Chip Select | Active-low enable: wiper updates only when CS = low; high state freezes interface and prevents EEPROM writes |
| 8 VCC | Power Supply | Primary power rail; powers internal logic, EEPROM, and analog resistor network; requires local 0.1µF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Retains last setting across power cycles without external memory or initialization firmware |
| Three-terminal interface | Eliminates need for I²C/SPI controllers or address decoding-reduces BOM and layout complexity |
| Industrial temperature rating | Ensures consistent 200kΩ resistance tracking and linearity across –40°C to +85°C ambient |
| Low standby current | Enables always-on brightness control in battery-operated PDAs and phones without measurable runtime impact |
| Command-initiated EEPROM write | Prevents accidental overwrites-storage occurs only on explicit CS/INC timing sequence, not on every adjustment |
Applications
| White LED Backlight Control | Portable Device Power Management |
|---|---|

IC Role / Device Role / Timing Role: Voltage divider setting resistor for FB pin of LED driver IC (e.g., MAX1910), directly controlling output current.

Equivalent & Alternatives
The following parts are listed as comparable options for similar nonvolatile digital potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD5171BRMZ-20 | 64-position, I²C interface, 10kΩ end-to-end resistance, 2.7V–5.5V supply | Requires microcontroller I²C port and firmware; better resolution but higher system integration cost | Choose when digital bus control and finer granularity outweigh simplicity and cost |
| MCP41010-I/P | 10kΩ, SPI interface, volatile wiper (no EEPROM), 2.7V–5.5V, 256 positions | Loses setting on power loss; needs host MCU to reload value at startup | Choose when frequent dynamic reconfiguration is needed and external memory or boot-time restore is acceptable |
Compared with AD5171BRMZ-20 and MCP41010-I/P, the DS4301Z-200 uniquely combines zero-software interface simplicity, EEPROM retention, and 200kΩ impedance-making it optimal for fixed-function, low-power, self-contained analog trimming where bus overhead or external memory is undesirable.

FAQ
What is the supply voltage range supported by the DS4301Z-200?
The DS4301Z-200 operates from 2.4V to 5.5V, making it compatible with single-cell lithium-ion batteries (nominal 3.7V), 3.3V logic rails, and legacy 5V systems. Operation below 2.4V may result in incomplete EEPROM loading or unreliable wiper control, while voltages above 5.5V exceed absolute maximum ratings and risk permanent damage.
Does the DS4301Z-200 retain its wiper setting after power is removed?
Yes, the DS4301Z-200 stores the wiper position in on-chip EEPROM. Upon power-up, once VCC reaches a stable ≥2.4V level, the stored setting is automatically loaded into the wiper register within 500µs. This behavior eliminates the need for external memory or host MCU initialization code.
How does the three-terminal interface of the DS4301Z-200 work?
The DS4301Z-200 uses CS (chip select), U/D (up/down), and INC (increment/decrement) pins. To adjust the wiper, pull CS low, set U/D to high (increment) or low (decrement), then apply high-to-low pulses to INC. Each pulse moves the wiper one step; no clock or data framing is required.
What is the maximum wiper current rating for the DS4301Z-200?
The DS4301Z-200 specifies a wiper current limit of ±1mA under DC conditions. Exceeding this may cause localized heating, resistance drift, or accelerated EEPROM wear. For LED current-setting applications, ensure the DS4301Z-200 operates as a voltage divider-not a current-carrying element-in the feedback path of a dedicated LED driver IC.
Is the DS4301Z-200 pin-compatible with other Maxim digital potentiometers?
No, the DS4301Z-200 is not pin-compatible with other Maxim digital potentiometers such as the DS1804 or DS3930. Its µSOP-8 pinout (INC/U/D/H/GND/W/L/CS/VCC) is unique to the DS4301 family. Substituting alternate parts requires PCB layout revision and interface logic adaptation.
