Product details
Overview
REF01Z-G106 from Maxim Integrated is a precision 10V voltage reference in an 8-pin ceramic DIP package, rated for -55°C to +125°C operation, with ±100mV initial output error (±1.0%), 65ppm/°C max temperature coefficient, and 1mA quiescent current. It supports single-supply operation from 13V to 33V and enables ±6% output adjustment via external trim resistor for system-level calibration in high-accuracy analog circuits.
For engineers reviewing the REF01Z-G106 datasheet, REF01Z-G106 pinout, REF01Z-G106 application, or REF01Z-G106 equivalent, key selection considerations include extended temperature range suitability, ceramic package reliability for harsh environments, trim-adjustable 10V output stability, and compatibility with legacy industrial instrumentation requiring MIL-PRF-38534–qualified references.
Technical Context
The REF01Z-G106 implements a bandgap-based reference core with internal trimming and laser-adjusted resistors to achieve stable 10V output across military-grade temperature extremes. Its architecture includes short-circuit protection, thermal shutdown, and low-noise design optimized for ADC/DAC reference use.
Unlike the REF02 family, REF01Z-G106 lacks a dedicated TEMP pin and is strictly a two-terminal reference (VOUT and TRIM), with no temperature transducer functionality. Input regulation is specified over 13V–33V, and load regulation holds within ±0.010%/mA up to 10mA sink/source capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 10.00 V ±100 mV at TA = +25°C - ensures absolute accuracy within 1% before system trim |
| Tempco (Max) | 65 ppm/°C over -55°C to +125°C - limits drift to ≤7.8 mV total across full range |
| Initial Error | ±100 mV (±1.0%) - sets baseline calibration requirement for post-trim system accuracy |
| Input Voltage Range | 13 V to 33 V - supports wide supply headroom for unregulated or noisy rails |
| Quiescent Current | 1.0–1.6 mA - enables low-power operation while maintaining stability under load |
| Output Adjustment | ±6% (±600 mV) via external 10kΩ potentiometer - allows precise binary alignment (e.g., 10.240V) |
| Package | Ceramic DIP-8 (J8-2), 0.300" width - provides hermetic sealing and superior thermal/mechanical robustness vs. plastic |
Pinout & Package
REF01Z-G106 uses an 8-pin ceramic dual-in-line package (DIP) with 0.300" body width and J8-2 footprint per Maxim drawing 21-0045A. The package is non-hermetic but offers enhanced moisture resistance and thermal cycling performance versus plastic DIP variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No Connection | Unused pin; must be left floating or tied to GND per layout best practice |
| 2 (GND) | Ground Reference | Primary return path for internal circuitry and external trim network |
| 3 (NC) | No Connection | Unused pin; identical to Pin 1 - no TEMP function (REF02-only feature) |
| 4 (VIN) | Positive Supply Input | Accepts 13V–33V DC; internal regulator drops excess voltage to bias reference core |
| 5 (TRIM) | Adjustment Terminal | Connects to wiper of 10kΩ potentiometer between VOUT and GND for ±6% output tuning |
| 6 (VOUT) | Precision Output | Stable 10V reference source; capable of sourcing/sinking up to 10mA with <0.01%/mA load regulation |
| 7 (NC) | No Connection | Unused pin; electrically isolated from die |
| 8 (NC) | No Connection | Unused pin; no internal connection - avoid routing signals nearby |
Key Features
| Feature | Design Value |
|---|---|
| Extended Temperature Range | -55°C to +125°C operation - qualified for aerospace, downhole, and defense systems where plastic packages fail |
| Laser-Trimmed Output | ±100mV initial error (±1.0%) - reduces need for external calibration in production test |
| Adjustable Output | ±6% trim range with minimal tempco shift (0.7 ppm/% change) - enables system-level error correction without degrading stability |
| Ceramic DIP Packaging | J8-2 footprint, 0.300" width - delivers superior long-term parameter stability and humidity resistance vs. plastic or SOIC |
| Short-Circuit Protection | Indefinite output short to GND or VIN - prevents damage during board bring-up or fault conditions |
Applications
| High-Accuracy Data Acquisition | Industrial Process Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF01HP-G106 | Same ceramic DIP-8 package, but rated only 0°C to +70°C and 25ppm/°C max tempco | Suitable for commercial-grade instrumentation; lacks extended temperature qualification | Select when cost sensitivity outweighs military-temperature requirements and tighter tempco is acceptable |
| REF01CESA+ | SOIC-8 package, -40°C to +85°C rating, 65ppm/°C tempco, RoHS-compliant | Designed for space-constrained industrial PCBs; no ceramic hermeticity or extreme-temp capability | Choose for modern surface-mount production where board area and lead-free compliance are mandatory |
Compared with REF01Z-G106, REF01HP-G106 trades military temperature range for lower cost and slightly better tempco, while REF01CESA+ sacrifices package robustness and extended range for SMT manufacturability and RoHS compliance - neither matches REF01Z-G106's combination of ceramic reliability and -55°C/+125°C operation.

FAQ
What is the operating temperature range of the REF01Z-G106?
The REF01Z-G106 is specified for continuous operation from -55°C to +125°C. This extended range is validated per MIL-PRF-38534 Class B screening and makes REF01Z-G106 suitable for aerospace, defense, and energy exploration applications where plastic-package references would fail due to thermal stress or parameter drift.
Does the REF01Z-G106 include a temperature output pin like the REF02?
No, the REF01Z-G106 does not have a temperature output pin. Pin 3 is designated NC (no connection), consistent with all REF01 variants. Only REF02 devices provide the TEMP pin with 2.1mV/°C output. REF01Z-G106 is a dedicated 10V reference with trim capability but no integrated temperature transduction function.
What is the maximum load current the REF01Z-G106 can drive while maintaining output accuracy?
The REF01Z-G106 guarantees output voltage accuracy within specification for load currents up to ±10mA. At 10mA sink or source, load regulation remains ≤0.010%/mA, meaning output deviation stays within ±0.1mV. Beyond 10mA, performance degrades, and short-circuit protection activates if output is forced to GND or VIN.
Can the REF01Z-G106 be used as a direct replacement for the REF01EP or REF01HP in existing designs?
REF01Z-G106 shares identical pinout and electrical behavior with REF01EP/REF01HP but adds extended temperature range and ceramic packaging. It is a drop-in replacement for board-level upgrades requiring higher reliability, though layout review is recommended to confirm thermal dissipation margins given its higher max operating temperature.
What is the purpose of the TRIM pin on the REF01Z-G106, and how is it configured?
The TRIM pin (Pin 5) on REF01Z-G106 connects to the wiper of a 10kΩ potentiometer placed between VOUT (Pin 6) and GND (Pin 2). Adjusting the potentiometer varies output voltage over ±6% (±600mV), enabling precise system calibration - e.g., setting 10.240V for binary-aligned ADC full-scale - without compromising temperature stability (tempco shift ≤0.7ppm/%).
