Product details
Overview
MX580JESA from Maxim Integrated is a three-terminal, temperature-compensated bandgap voltage reference delivering +2.5V ±75mV (±3%) output with 10ppm/°C temperature stability, 1.5mA quiescent current, and operation from 4.5V to 30V input - designed for precision ADC/DAC biasing in industrial data acquisition systems.
For engineers reviewing the MX580JESA datasheet, MX580JESA pinout, MX580JESA application, or MX580JESA equivalent, key selection factors include its -40°C to +85°C extended temperature range, SO-8 package compatibility, unadjusted accuracy, low noise (60µVP-P, 0.1Hz–10Hz), and long-term stability of 250µV per month.
Technical Context
The MX580JESA implements a curvature-corrected bandgap core with on-chip temperature compensation to achieve stable 2.5V output across its full operating temperature range. It requires no external trimming and maintains regulation under load currents up to 10mA with ≤10mV load regulation.
Its SO-8 package supports surface-mount assembly in space-constrained industrial modules, and the device draws only 1.5mA while sustaining 4.5V–30V supply rejection - enabling direct integration into +5V-powered analog signal chains without additional regulators.
Key Specifications

|---|---|
| Output Voltage | +2.5V ±75mV (±3% initial tolerance at TA = 25°C) |
| Temp. Coefficient | 10ppm/°C (max over -40°C to +85°C - enables drift-free 12-bit designs) |

| Quiescent Current | 1.5mA (enables low-power portable instrumentation use) |
| Load Regulation | ≤10mV (0–10mA load - ensures stable reference under dynamic converter loading) |
| Long-Term Stability | 250µV/month (reduces calibration frequency in field-deployed meters) |
| Output Noise | 60µVP-P, 0.1Hz–10Hz (minimizes quantization error in high-resolution ADCs) |
Pinout & Package
MX580JESA is housed in an 8-pin SOIC (SO) package with exposed pad thermal enhancement, compliant with JEDEC MS-012 standard (body size 4.9mm × 6.0mm, 1.27mm pitch). Pin 1 is marked by a beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect | Internally unused - must be left floating or grounded per layout best practice |
| 2 | No Connect | Internally unused - no routing required |
| 3 | GND | Analog ground reference - requires low-impedance connection to system AGND plane |
| 4 | +VS | Positive supply input - accepts 4.5V–30V; bypass with 0.1µF ceramic near pin |
| 5 | +VS | Second supply connection - improves PSRR and thermal distribution in SO package |
| 6 | +VS | Third supply connection - used for internal bias distribution; tie to +VS rail |
| 7 | +VS | Fourth supply connection - enhances supply decoupling integrity |
| 8 | +2.5V | Precision output - delivers regulated 2.5V; route with short, low-inductance trace to ADC REF pin |
Key Features
| Feature | Design Value |
|---|---|
| No external adjustment required | Factory-trimmed bandgap eliminates potentiometer, calibration labor, and long-term drift from trim components |
| 10ppm/°C tempco | Enables <0.025% full-scale error over -40°C to +85°C - sufficient for 12-bit linearity without software correction |
| 250µV/month long-term stability | Reduces annual calibration drift to <3mV - critical for remote measurement systems with infrequent maintenance |
| 60µVP-P low-frequency noise | Minimizes effective number of bits (ENOB) loss in 16-bit SAR ADCs sampling at ≤100ksps |
| 4.5V–30V wide input range | Eliminates need for dedicated LDO when interfacing with unregulated 24V industrial buses or battery-backed supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5025AIDR | Initial accuracy ±0.05%, 3ppm/°C tempco, 3.6mA IQ, SO-8 | Higher precision but higher power - suited for metrology-grade instruments, not portable devices | Select when sub-0.01% total error budget is required and supply headroom permits >3.6mA draw |
| ADR441BRZ | Initial accuracy ±0.04%, 3ppm/°C tempco, 4.5mA IQ, SO-8 | Lower noise (4.8µVRMS) but higher cost and IQ - preferred in low-noise DAQ front-ends | Choose for 16-bit+ systems where noise dominates error budget and power is secondary |
Compared with REF5025AIDR and ADR441BRZ, MX580JESA offers the optimal balance of extended temperature support (-40°C to +85°C), moderate accuracy (±75mV), low IQ (1.5mA), and SO-8 compatibility - making it ideal for cost-sensitive, battery-aware, industrial-grade data converters where 12-bit performance is sufficient.

FAQ
What is the operating temperature range of the MX580JESA?
The MX580JESA is rated for continuous operation from -40°C to +85°C. This extended temperature grade distinguishes it from commercial-grade variants (e.g., MX580JCSA, 0°C to +70°C) and makes it suitable for deployment in outdoor industrial enclosures, automotive under-hood environments, and uncontrolled ambient installations where thermal cycling occurs. The device maintains its ±75mV output tolerance and 10ppm/°C temperature coefficient across this full range.
Does the MX580JESA require external trimming or calibration?
No, the MX580JESA does not require external trimming or calibration. It uses a factory-laser-trimmed, curvature-compensated bandgap architecture that achieves ±75mV initial accuracy and 10ppm/°C temperature stability without user adjustment. This eliminates the need for potentiometers, calibration firmware, or post-assembly test corrections - reducing BOM count, assembly time, and long-term drift risk in the MX580JESA-based design.
What is the maximum load current supported by the MX580JESA?
The MX580JESA supports a maximum output current of 10mA while maintaining specified load regulation (≤10mV change from no-load to full-load). Exceeding 10mA may cause output voltage deviation beyond ±75mV and increased thermal stress. For applications requiring higher drive capability - such as powering multiple ADC references or op-amp bias networks - a buffer amplifier should be used downstream of the MX580JESA output.
Can the MX580JESA be used with 3.3V supply rails?
No, the MX580JESA cannot operate from a 3.3V supply. Its minimum input voltage is 4.5V, as specified in the Absolute Maximum Ratings and Electrical Characteristics tables. Attempting to power the MX580JESA from 3.3V will result in improper bandgap biasing and failure to regulate at +2.5V. For 3.3V systems, consider alternatives like the MAX6126AASA25+ (2.5V, 3.3V min VIN) or REF3025AIDBZR.
How does the MX580JESA compare to the MX580LCSA in terms of accuracy and use case?
The MX580JESA has ±75mV (±3%) initial output tolerance and is rated for -40°C to +85°C, whereas the MX580LCSA offers ±10mV (±0.4%) accuracy but only operates from 0°C to +70°C. Thus, MX580JESA trades tighter accuracy for wider temperature coverage - making it preferable in ruggedized field instruments, while MX580LCSA suits lab-grade equipment where ambient control is guaranteed. Both share identical SO-8 packaging and pinout.
