Product details
Overview
The MAX6241BEPA+ from Maxim Integrated is a precision 4.096V buried-zener voltage reference with ±0.02% initial accuracy, 7.0ppm/°C max temperature coefficient over –40°C to +85°C, and 2.4µVP-P (0.1Hz–10Hz) output noise-designed for high-resolution ADC/DAC biasing in metrology-grade instrumentation.
For engineers reviewing the MAX6241BEPA+ datasheet, MAX6241BEPA+ pinout, MAX6241BEPA+ application, or MAX6241BEPA+ equivalent, key selection criteria include guaranteed ±15mA sourcing/sinking capability, optional external trim (±40mV range), NR-pin noise reduction support, and stability with 0–100µF capacitive loads without compensation.
Technical Context
This device uses buried-zener topology with on-chip temperature compensation to achieve laboratory-grade stability without heater power. Its low 2.4µVP-P noise and 20ppm/1000h long-term drift are validated across the full –40°C to +85°C industrial temperature range.
It delivers 4.096V output with ±15mA load regulation performance (≤7ppm/mA sourcing, ≤7ppm/mA sinking), 8V–36V input range, and fast 8µs turn-on settling to ±0.01%. The TRIM and NR pins enable system-level calibration and wideband noise filtering without external op-amps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.004V at +25°C - tight tolerance enables direct interface with 12-bit to 16-bit SAR and sigma-delta ADCs without gain calibration. |
| Tempco (Max) | 7.0ppm/°C over –40°C to +85°C - ensures ≤±0.35mV total drift across full industrial range, critical for portable calibrators. |
| Noise (0.1–10Hz) | 2.4µVP-P - low enough to avoid degrading ENOB in 16-bit data converters operating at <10ksps. |
| Load Regulation | ≤7ppm/mA sourcing & sinking - supports dynamic current loads up to ±15mA while maintaining sub-30ppm error. |
| Supply Current | 2.9mA typical - enables low-power operation in battery-backed precision sensors and handheld DMMs. |
| Long-Term Stability | 20ppm/1000h - predictable aging behavior allows drift compensation in automated test equipment with multi-year calibration cycles. |
| Input Voltage Range | 8V to 36V - accommodates unregulated industrial rails and legacy 12V/24V systems without external LDO pre-regulation. |
Pinout & Package
MAX6241BEPA+ uses an 8-pin plastic DIP package (PDIP) with lead(Pb)-free/RoHS-compliant finish. Pins 1, 7, and 8 are internally connected and must remain unconnected in PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 2 (IN) | Positive power-supply input | Accepts 8V–36V; internal regulator rejects ripple-no external filter required for moderate-noise supplies. |
| 3 (NR) | Noise reduction terminal | Connects to 1µF capacitor to reduce wideband noise; open-circuit if unused-no pull-up/down needed. |
| 4 (GND) | Analog ground reference | Must be star-connected to system AGND; separates reference return from digital or power return paths. |
| 5 (TRIM) | External voltage trim input | Accepts 0–4.096V for ±40mV adjustment via 10kΩ potentiometer-trimming does not degrade tempco or noise. |
| 6 (OUT) | Precision reference output | Delivers stable 4.096V; drives 0–100µF capacitive loads directly-no series resistor or isolation buffer required. |
Key Features
| Feature | Design Value |
|---|---|
| Buried-zener core | Enables 2.4µVP-P (0.1–10Hz) noise and 20ppm/1000h stability-superior to bandgap references in metrology applications. |
| ±15mA sourcing/sinking | Eliminates need for external buffer op-amps when driving ADC reference inputs, multiplexer switches, or DAC bias networks. |
| Optional NR capacitor | 1µF on NR pin reduces wideband noise by >10dB above 10Hz-critical for FFT-based spectral analysis systems. |
| Industry-standard pinout | Pin-compatible with legacy MAX62xx family and many competing 8-pin DIP references-enables drop-in replacement in existing designs. |
| Stable with all capacitive loads | Operates reliably from 0µF to 100µF output capacitance-supports ceramic, tantalum, and electrolytic bypass without phase-margin risk. |
Applications
| High-Resolution Data Acquisition | Digital Multimeters (DMMs) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5040IDR | 4.096V, 3ppm/°C max, 1.8µVP-P, SO-8 package, 3.6mA supply current | Lower tempco/noise but limited to ±10mA output; requires external buffer for >10mA loads | Select for ultra-low-drift lab instruments where board space is constrained and load current ≤10mA. |
| ADR444BRZ | 4.096V, 3ppm/°C max, 1.75µVP-P, SO-8, 4.5mA supply current, higher cost | Superior noise and tempco but no TRIM/NR pins; fixed-output only | Select when absolute minimum noise is required and external trimming is unnecessary-e.g., fixed-gain medical ADC modules. |
Compared with REF5040IDR and ADR444BRZ, the MAX6241BEPA+ trades minor tempco/noise margin for integrated trim and noise-reduction flexibility, ±15mA drive, and PDIP compatibility-making it optimal for industrial field instruments requiring field recalibration and robust load handling.

FAQ
What is the maximum operating temperature range for the MAX6241BEPA+?
The MAX6241BEPA+ is rated for –40°C to +85°C operation, confirmed in the Ordering Information table and Electrical Characteristics section. This extended industrial temperature range ensures reliable performance in factory-floor PLCs, outdoor instrumentation, and automotive test rigs where ambient temperatures exceed commercial-grade limits. The MAX6241BEPA+ maintains its 7.0ppm/°C max tempco and ±0.02% initial accuracy across this full range.
Can the MAX6241BEPA+ drive a 100µF output capacitor without instability?
Yes-the MAX6241BEPA+ is explicitly characterized as stable with capacitive loads from 0µF to 100µF across all load currents, per the "Bypassing" section and Typical Operating Characteristics. This eliminates need for series isolation resistors or external compensation networks, simplifying layout in high-EMI environments like motor-drive feedback circuits where large bulk capacitance is used for local energy storage.
How much can the output voltage of the MAX6241BEPA+ be adjusted using the TRIM pin?
The TRIM pin on the MAX6241BEPA+ supports ±40mV output adjustment (±0.98% of 4.096V), verified in the MAX6241 Electrical Characteristics table under "Trim-Adjustment Range." This is achieved using a 10kΩ potentiometer between OUT and GND, with wiper connected to TRIM. External trimming does not affect temperature coefficient or long-term stability-critical for field-calibrated devices.
Is the MAX6241BEPA+ RoHS-compliant?
Yes-the "+" suffix in MAX6241BEPA+ denotes a lead(Pb)-free and RoHS-compliant package, as stated in the "Ordering Information" and "Package Information" sections. The device uses a standard 8-pin plastic DIP (PDIP) package with matte tin lead finish, meeting EU Directive 2011/65/EU and China RoHS II requirements without exemptions.
What is the typical turn-on settling time for the MAX6241BEPA+?
The MAX6241BEPA+ achieves turn-on settling to ±0.01% of final value in 8µs at +25°C, per the Electrical Characteristics table. This fast settling enables use in burst-mode data acquisition systems and time-domain reflectometry instruments where reference activation must synchronize tightly with sampling clocks-without requiring external delay circuits or power-good assertion logic.
