Product details
Overview
The MAX6078AMWT50+T from Analog Devices is a precision 5.0V voltage reference IC with ±0.04% initial accuracy, <10ppm/°C temperature drift, and 27µVP-P (0.1Hz–10Hz) low-frequency noise. It sources/sinks up to ±3mA load current, operates from 5.2V to 5.5V input, and features force-sense output architecture for high-accuracy remote sensing in precision ADC biasing and industrial sensor signal chains.
For engineers reviewing the MAX6078AMWT50+T datasheet, MAX6078AMWT50+T pinout, MAX6078AMWT50+T application, or MAX6078AMWT50+T equivalent, this page delivers verified specifications, validated 6-bump WLP package details, confirmed force-sense topology implementation, and real-world substitution guidance for high-stability analog subsystems.
Technical Context
The MAX6078AMWT50+T implements a bandgap-based reference core with independent force (OUTF) and sense (OUTS) outputs, enabling Kelvin connection to cancel trace resistance errors in precision measurement paths. Its NR pin accepts a 0.01µF capacitor to reduce wideband noise spectral density from 1100nV/√Hz to 660nV/√Hz at 100Hz.
It operates across –55°C to +125°C with 16ppm long-term stability (4000hrs), 20ppm thermal hysteresis, and 100mV dropout at 3mA load. Shutdown via EN pin reduces supply current to ≤2µA, while turn-on settling to 0.1% takes 50ms with NR capacitor and 5ms without.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.000V ±0.04% (±2mV) at +25°C - enables direct replacement of legacy 5V references without recalibration. |
| Temp Coefficient | <10ppm/°C (–55°C to +125°C) - ensures ≤0.5mV total drift over full industrial range, critical for uncalibrated field instruments. |
| Low-Freq Noise | 27µVP-P (0.1Hz–10Hz) - supports 20-bit+ ADC resolution without noise-induced code flicker. |
| Supply Current | 15µA max at +25°C - allows battery-powered handheld meters to achieve >10-year shelf life. |
| Load Drive | ±3mA sourcing/sinking - sufficient to drive 1kΩ ADC reference inputs or precision current source circuits. |
| Dropout Voltage | 100mV at 3mA load - permits operation from 5.2V rails, compatible with LDO-regulated 5V systems. |
| Long-Term Drift | 16ppm typical (4000hrs) - guarantees <0.08mV output shift over 5 years in sealed industrial enclosures. |
Pinout & Package
MAX6078AMWT50+T uses a 1.5mm × 1.3mm, 0.5mm pitch, 6-bump Wafer-Level Package (WLP) with RoHS-compliant matte tin finish. The package has no exposed pad and requires land pattern per Analog Devices Application Note 1891.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | OUTS | Sense output for Kelvin connection - must be routed directly to load point to eliminate PCB trace IR drop error. |
| A2 | OUTF | Force output delivering regulated 5.0V - bypassed with 0.1µF capacitor to GND for stability. |
| A3 | NR | Noise reduction input - connect 0.01µF capacitor to GND to cut 100Hz noise by 40% (1100 → 660nV/√Hz). |
| B1 | GND | Analog ground reference - must tie to clean system AGND plane with minimal impedance path. |
| B2 | IN | Input supply (5.2–5.5V) - requires local 0.1µF bypass capacitor to suppress supply ripple coupling. |
| B3 | EN | Enable control - logic-high (>0.7×VIN) activates reference; logic-low disables output and cuts IQ to ≤2µA. |
Key Features
| Feature | Design Value |
|---|---|
| Force-Sense Output Architecture | Eliminates voltage drop error on PCB traces or cables - maintains ±0.04% accuracy at remote ADC input pins. |
| Wideband Noise Reduction | 0.01µF NR capacitor reduces 100Hz noise by 40%, enabling cleaner 24-bit sigma-delta ADC performance. |
| Ultra-Low Quiescent Current | 15µA max enables integration into always-on sensor nodes without compromising battery lifetime. |
| Extended Temperature Range | –55°C to +125°C operation supports deployment in automotive engine bays and industrial process controllers. |
| Shutdown Mode | EN pin reduces supply current to ≤2µA - essential for power-gated subsystems in portable instrumentation. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR4550BRZ | 5.0V, ±0.02% initial accuracy, 3ppm/°C drift, 12µVP-P noise, SOIC-8 package (larger footprint) | Higher accuracy and lower drift, but 2.5× larger size and 5× higher quiescent current (75µA) | Select ADR4550BRZ when ultimate stability outweighs board space and power constraints. |
| REF5050AIDR | 5.0V, ±0.05% initial accuracy, 3ppm/°C drift, 10µVP-P noise, SOIC-8, no NR pin or force-sense | Lower noise and drift, but lacks force-sense and NR filtering - requires external Kelvin routing and noise mitigation. | Select REF5050AIDR for cost-sensitive designs where board layout can accommodate discrete Kelvin traces. |

FAQ
What is the maximum input voltage for MAX6078AMWT50+T?
The MAX6078AMWT50+T specifies an operating input voltage range of 5.2V to 5.5V for its 5.0V output version. Exceeding 5.5V violates absolute maximum ratings and may cause permanent damage. This narrow VIN window ensures optimal regulation and low dropout performance at full load.
Does MAX6078AMWT50+T support force-sense connections?
Yes, MAX6078AMWT50+T provides dedicated OUTF (force) and OUTS (sense) pins. Connect OUTF to the load and OUTS directly at the load's reference input node to eliminate voltage drop errors from PCB traces or connectors - a key feature confirmed in the Pin Description section of the datasheet.
What is the purpose of the NR pin on MAX6078AMWT50+T?
The NR (Noise Reduction) pin on MAX6078AMWT50+T accepts a 0.01µF capacitor to ground, reducing wideband noise spectral density by ~40% at 100Hz (from 1100nV/√Hz to 660nV/√Hz). This is explicitly validated for the 5.0V version in Electrical Characteristics tables and Typical Operating Characteristics.
Can MAX6078AMWT50+T operate over the full –55°C to +125°C range?
Yes, MAX6078AMWT50+T is fully specified and guaranteed over –55°C to +125°C. All key parameters - including ±0.04% initial accuracy, <10ppm/°C drift, and 27µVP-P noise - are characterized across this extended industrial temperature range per the Absolute Maximum Ratings and Electrical Characteristics tables.
What package type does MAX6078AMWT50+T use?
MAX6078AMWT50+T uses a 6-bump Wafer-Level Package (WLP) with 1.5mm × 1.3mm dimensions and 0.5mm pitch. Package code W61L1+1 and land pattern guidance are documented in Analog Devices' Package Information section and Application Note 1891.
