Product details
Overview
REF01HP+ from Maxim Integrated is a precision 10V voltage reference IC in an 8-pin plastic DIP package, featuring ±50mV initial output error, 25ppm/°C temperature coefficient over 0°C to +70°C, 1mA quiescent current, and ±6% output adjustability via external resistor-used in high-accuracy ADC/DAC calibration and industrial instrumentation.
For engineers reviewing the REF01HP+ datasheet, REF01HP+ pinout, REF01HP+ application, or REF01HP+ equivalent, this page delivers verified electrical parameters, thermal stability data, trim circuit implementation guidance, and validated alternatives for precision analog system design.
Technical Context
The REF01HP+ implements a bandgap-based reference core with internal trimming for 10V nominal output, supporting single-supply operation from 13V to 33V input. Its output is adjustable ±600mV (±6%) using a 10kΩ potentiometer between TRIM and GND without degrading temperature stability beyond 0.7ppm/°C per 100mV of adjustment.
It delivers low-noise performance (20–30µVP-P, 0.1Hz–10Hz), load regulation of 0.006–0.012%/mA (0–8mA), and line regulation of 0.007–0.012%/V (13–33V), with turn-on settling time of 400µs to ±0.1%-all specified across its full operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 9.95V to 10.05V at 25°C - ensures 10V reference accuracy within ±50mV for high-resolution data conversion systems. |
| Tempco | 25ppm/°C max (0°C to +70°C) - guarantees ≤1.75mV total drift over full operating range, critical for stable calibration references. |
| Initial Error | ±50mV - enables direct use in 12-bit systems (LSB = 2.44mV at 10V) without post-manufacture trimming. |
| Quiescent Current | 1.0–1.4mA - supports low-power portable instrumentation while maintaining output regulation under load. |
| Input Voltage Range | 13V to 33V - allows compatibility with standard industrial 15V/24V rails and accommodates supply ripple without output degradation. |
| Output Adjust Range | ±6% (±600mV) - permits binary-aligned outputs (e.g., 10.240V) and system-level offset correction without external amplification. |
| Short-Circuit Duration | Indefinite - provides robust fault tolerance during board bring-up or transient overloads without latch-up or damage. |
Pinout & Package
REF01HP+ uses an 8-pin plastic DIP (P8-2) package with 0.3-inch width and through-hole mounting. Pin 1 is VOUT, Pin 2 is TRIM, Pin 4 is GND, Pin 5 is N.C., Pin 6 is VIN, Pins 3/7/8 are N.C. No TEMP pin - distinct from REF02 series.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VOUT) | Reference Output | 10V precision source; requires low-ESR bypass capacitor (≥1µF) for noise suppression and stability. |
| 2 (TRIM) | Adjustment Terminal | Connects to wiper of 10kΩ potentiometer between GND and VOUT to shift output ±6% without affecting tempco significantly. |
| 4 (GND) | Analog Ground Reference | Must be star-connected to system ground plane; separates reference return from power or digital ground currents. |
| 6 (VIN) | Positive Supply Input | Accepts 13–33V DC; internal regulator rejects >60dB of supply ripple up to 10kHz per typical characteristics. |
| 5, 3, 7, 8 | No Connection | Unbonded; must remain unconnected and unstubbed to avoid parasitic coupling or ESD path formation. |
Key Features
| Feature | Design Value |
|---|---|
| Pretrimmed 10V Output | Factory-trimmed to ±50mV at 25°C - eliminates need for user calibration in production test fixtures and field instruments. |
| Adjustable Output Range | ±6% (±600mV) via external potentiometer - supports custom reference voltages like 10.240V for binary-scaled ADCs without external op-amps. |
| Low Temperature Drift | 25ppm/°C max over 0°C to +70°C - limits total error to <1.75mV across operating range, enabling 14-bit effective resolution. |
| Short-Circuit Protection | Indefinite short-circuit survival at VO or VIN - prevents failure during probe contact, solder bridging, or layout errors in prototype validation. |
| Low Quiescent Current | 1.0–1.4mA - reduces self-heating (<15mW at 15V), minimizing thermal gradient-induced drift in sealed enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF01EP+ | Lower tempco (8.5ppm/°C) and tighter initial error (±30mV); same 8-pin DIP package and pinout. | Suitable where extended temperature stability is required (e.g., lab-grade equipment), but higher cost and same power envelope. | Select REF01EP+ when system-level drift budget demands <0.6mV over 0–70°C, accepting premium pricing for enhanced spec. |
| MAX6035AESA+ | 5V output, SOT23-3 package, 15ppm/°C tempco, 1.8–5.5V supply; no trim capability. | Used in space-constrained, low-voltage embedded systems (e.g., IoT sensor nodes), not compatible with 10V or DIP layouts. | Choose MAX6035AESA+ only for new 5V, surface-mount designs where size and supply voltage constrain REF01HP+ use. |
Compared with REF01HP+, REF01EP+ offers superior thermal stability at higher cost and identical form factor, while MAX6035AESA+ trades adjustability and voltage level for miniaturization and low-voltage operation-neither is pin-compatible, and both require PCB redesign for substitution.

FAQ
What is the maximum input voltage rating for REF01HP+?
The absolute maximum input voltage for REF01HP+ is 40V, as specified in the Absolute Maximum Ratings table. However, the recommended operating input voltage range is 13V to 33V to ensure stable 10V output regulation and maintain specified line regulation (0.007–0.012%/V). Exceeding 33V may increase power dissipation beyond safe limits in the 8-pin DIP package.
Does REF01HP+ include a temperature output pin like REF02?
No, REF01HP+ does not include a temperature output pin. Pin 3 is designated N.C. (No Connection) per the official pin configuration diagram. The TEMP pin functionality is exclusive to REF02-series devices. REF01HP+ is strictly a 10V reference IC with TRIM, VOUT, VIN, and GND terminals-no linear temperature transducer capability.
Can REF01HP+ be used to generate a 10.240V reference for binary-scaled ADCs?
Yes, REF01HP+ supports precise 10.240V output generation via its TRIM terminal. Using a 10kΩ potentiometer between TRIM and GND adjusts the output over ±6% (±600mV), enabling accurate 10.240V setting. The datasheet confirms that output adjustment introduces only ~0.7ppm/°C tempco change per 100mV, preserving stability for 12-bit and 14-bit ADC applications.
What is the short-circuit current limit of REF01HP+?
The short-circuit current of REF01HP+ is 30mA, measured when VOUT is forced to 0V. This value is consistent across REF01E/H/C variants and is guaranteed in the Electrical Characteristics tables. The device sustains indefinite short-circuit conditions at either VOUT or VIN without damage, making it robust for bench testing and fault-prone environments.
Is REF01HP+ RoHS-compliant and lead-free?
Yes, REF01HP+ is RoHS-compliant and lead-free, as indicated by the "+" suffix in the part number per Maxim's ordering information. The "+" denotes a lead-free package, and the device meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for standard reflow profiles. Full compliance documentation is available in Maxim's official packaging reports.
