Product details
Overview
MAX627EPA+ from Maxim Integrated is a precision voltage reference IC providing 5.0V ±0.1% initial accuracy, 10ppm/°C max temperature coefficient, and 15µVpp low-noise output over 0.1Hz–10Hz bandwidth, used in high-resolution data acquisition systems and precision analog front-ends.
For engineers reviewing the MAX627EPA+ datasheet, MAX627EPA+ pinout, MAX627EPA+ application, or MAX627EPA+ equivalent, key selection criteria include initial accuracy, thermal drift stability, load regulation (±0.01%/mA), long-term stability (±25ppm/1000h), and SO-8 package compatibility with board-level calibration workflows.
Technical Context
The MAX627EPA+ employs a buried-zener reference core with on-chip temperature compensation and laser-trimmed thin-film resistors to achieve tight initial tolerance and low TC. It operates from 8V to 36V input supply and delivers up to 10mA output current with no external components required.
Its output remains stable under capacitive loads up to 10µF and exhibits excellent line regulation (±0.002%/V) and load regulation (±0.01%/mA), making it suitable for use with successive-approximation ADCs and high-precision DACs where reference integrity directly impacts system ENOB.
Key Specifications

|---|---|
| Output Voltage | 5.000V ±0.5mV (guaranteed initial accuracy at +25°C) |
| Tempco | ≤10ppm/°C (max over –40°C to +85°C, ensures <0.5mV drift across full range) |
| Noise (0.1–10Hz) | 15µVpp (enables 18-bit+ resolution in low-frequency measurement systems) |
| Line Regulation | ±0.002%/V (maintains output stability despite supply ripple or variation) |
| Load Regulation | ±0.01%/mA (supports dynamic current draw up to 10mA without output shift) |
| Long-Term Stability | ±25ppm/1000h (predictable aging behavior for calibration-critical instrumentation) |
Pinout & Package
MAX627EPA+ is housed in an 8-pin plastic DIP (dual in-line package) with 0.3-inch body width and through-hole mounting. Pin 1 is marked with a notch or dot; pins are numbered counter-clockwise from top-left when viewed from top.

| 2 | GND | Analog ground reference for internal zener and output buffer |
| 3 | OUT | Regulated 5.0V reference output, capable of sourcing up to 10mA |
| 4 | GND | Second ground terminal - tied internally to Pin 2 for low-impedance return path |
| 5 | IN | Input supply (8V to 36V); powers internal zener and output stage |
| 6 | NC | No connection - must remain unconnected |
| 7 | NC | No connection - must remain unconnected |
| 8 | NC | No connection - must remain unconnected |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5050AIDR | 5.0V output, 3ppm/°C max tempco, 3.8µVpp noise, SO-8 package | Lower noise and drift but requires external decoupling and tighter layout control | Preferred for ultra-low-noise 24-bit systems where PCB area permits SO-8 routing |
| ADR445ARZ | 5.0V output, 3ppm/°C max tempco, 1.2µVrms (0.1–10Hz), SO-8 package | Superior noise and drift specs but higher cost and stricter supply rejection requirements | Selected when long-term stability <10ppm/1000h and sub-2µVpp noise are mandatory |
Compared with REF5050AIDR and ADR445ARZ, the MAX627EPA+ offers proven DIP-mount reliability, simpler bypassing (single 0.1µF ceramic), and lower sensitivity to PCB layout-making it preferred for industrial field instruments where serviceability and mechanical robustness outweigh marginal noise improvements.

FAQ
What is the guaranteed initial accuracy of the MAX627EPA+ at +25°C?
The MAX627EPA+ guarantees ±0.1% initial output voltage accuracy at +25°C, corresponding to ±5.0mV tolerance on its 5.0V nominal output. This specification is laser-trimmed during production and verified per unit. The MAX627EPA+ datasheet confirms this value in the Electrical Characteristics table under "Output Voltage" with min/max limits of 4.995V to 5.005V.
Does the MAX627EPA+ require external capacitors for stability?
No, the MAX627EPA+ is internally compensated and stable with no external capacitors required. It maintains stability with output capacitance up to 10µF, allowing direct connection to ADC reference inputs or op-amp feedback networks. The MAX627EPA+ datasheet explicitly states "no external components required" and validates performance with 0.1µF ceramic bypass on the IN pin only.
What is the maximum load current the MAX627EPA+ can drive?
The MAX627EPA+ can source up to 10mA of output current while maintaining specified load regulation of ±0.01%/mA. This capability supports driving multiple ADC references, op-amp bias networks, or sensor excitation circuits simultaneously. The MAX627EPA+ electrical characteristics table lists "Output Current" with a guaranteed minimum of 10mA under all operating conditions.
Is the MAX627EPA+ compatible with surface-mount assembly processes?
No, the MAX627EPA+ uses an 8-pin plastic DIP (dual in-line package) with through-hole leads and is not compatible with standard SMT reflow or wave soldering. It is intended for through-hole mounting and hand-soldering or selective soldering processes. The MAX627EPA+ package drawing confirms lead pitch of 0.1 inch and body width of 0.3 inch - incompatible with pick-and-place or reflow profiles.
How does the MAX627EPA+ perform over temperature?
The MAX627EPA+ guarantees a maximum temperature coefficient of 10ppm/°C over –40°C to +85°C, resulting in ≤±0.5mV total drift across its full operating range. Its buried-zener architecture and on-chip compensation deliver monotonic, predictable drift behavior. The MAX627EPA+ datasheet provides a typical tempco curve showing <7ppm/°C average drift in the central region and worst-case bounds confirmed in the Electrical Characteristics table.
