Product details
Overview
MAX6023EBT41 from Maxim Integrated is a precision, low-power, low-dropout series-mode voltage reference in a 5-bump UCSP package, delivering a stable 4.096V output with ±0.20% initial accuracy and ≤30ppm/°C temperature coefficient over –40°C to +85°C. It operates from (VOUT + 0.2V) to 12.6V input, draws only 35µA max supply current, and maintains stability with up to 2.2nF capacitive load-ideal for high-resolution ADC biasing in portable data acquisition systems.
For engineers reviewing the MAX6023EBT41 datasheet, MAX6023EBT41 pinout, MAX6023EBT41 application, or MAX6023EBT41 equivalent, this page delivers verified electrical specs, UCSP package layout, real-world use cases in battery-powered instrumentation, and validated alternative options for voltage reference selection.
Technical Context
The MAX6023EBT41 implements a laser-trimmed bandgap core with proprietary curvature correction to achieve <30ppm/°C drift and ±0.20% initial accuracy at 4.096V. Its series-mode architecture enables sourcing/sinking up to 500µA while maintaining ≤200mV dropout at full load.
Unlike shunt references, it exhibits only 0.8µA/V supply current variation across input voltage and requires no external compensation capacitor-achieving dynamic stability from 0 to 2.2nF load capacitance without oscillation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.20% at +25°C - matches common 12-bit DAC/ADC full-scale reference points |
| Initial Accuracy | ±0.20% - eliminates need for system-level calibration in precision measurement |
| Temp Coefficient | ≤30ppm/°C - ensures <±1.2mV drift over –40°C to +85°C operating range |
| Dropout Voltage | 100–200mV at 500µA - supports operation from 4.296V input, enabling single-cell Li-ion compatibility |
| Supply Current | 27–35µA - extends battery life in always-on sensor nodes beyond 10 years at 1µA average load |
| Line Regulation | ≤160µV/V - rejects input ripple without additional filtering in noisy power rails |
| Noise (10Hz–10kHz) | 200µVRMS - preserves SNR in 16-bit+ data converters |
Pinout & Package
MAX6023EBT41 uses a 5-bump UCSP package (1.0mm × 1.5mm × 0.3mm), optimized for ultra-low profile and minimal PCB footprint. Bumps are on the bottom side; top-side markings include "AAQ".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A3 | I.C. | Internally connected; must remain unconnected on PCB - floating bumps prevent unintended parasitic coupling |
| A2 | GND | Reference ground return path - requires low-impedance connection to system AGND plane |
| B1 | OUT | Stable 4.096V reference output - routed with short, guarded trace to ADC REF+ or DAC VREF |
| B3 | IN | Input supply pin - accepts 4.296V to 12.6V; decoupling capacitor recommended within 2mm |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Stable with 0–2.2nF load capacitance - eliminates BOM cost and board space for ceramic cap in space-constrained designs |
| Low dropout voltage | 100mV min at 500µA - enables direct regulation from low-headroom supplies like buck converter outputs |
| Ultra-low quiescent current | 27µA typical - reduces standby power in wake-on-event sensor systems |
| Supply current stability | 0.8µA/V variation - minimizes error contribution from input rail fluctuations in battery-powered systems |
| UCSP footprint | 1.0mm × 1.5mm - occupies 65% less area than SOT23-5, enabling placement adjacent to high-speed ADCs |
Applications
| Portable Data Acquisition | Industrial Sensor Transmitters |
|---|---|

IC Role / Device Role / Timing Role: Supplies shared 4.096V reference to multiple ADC channels and internal voltage monitor. Use Value: Matches industry-standard 4.096V reference point for IEEE 1459 compliance testing; long-term stability <50ppm/1000hr prevents calibration drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3440BRJZ-R7 | 4.096V, ±0.1% initial accuracy, 3 ppm/°C drift, SOT23-5 package, 4.5µA supply current | Lower drift and higher accuracy but higher cost; requires external 100nF output capacitor for stability | Select when ultra-low drift dominates over size/cost; not drop-in due to capacitor requirement and larger footprint |
| REF3340AIDBVR | 4.096V, ±0.2% initial accuracy, 50ppm/°C drift, SOT23-3 package, 3.9µA supply current | Lower power but higher tempco; limited to 500µA load; no guaranteed 2.2nF capacitive-load stability | Choose for ultra-low-power sub-µA sleep modes where moderate drift is acceptable; verify stability with target load |
Compared with ADR3440BRJZ-R7 and REF3340AIDBVR, MAX6023EBT41 uniquely balances 0.2% accuracy, 30ppm/°C drift, UCSP size, and capacitor-free operation-making it optimal for space-constrained, battery-powered precision measurement where moderate power and proven 2.2nF load tolerance are critical.

FAQ
What is the maximum load current supported by MAX6023EBT41 without exceeding specified dropout?
MAX6023EBT41 supports up to 500µA load current while maintaining ≤200mV dropout voltage, as confirmed in the Electrical Characteristics table for MAX6023EBT41. At 500µA, dropout is guaranteed between 100mV and 200mV across –40°C to +85°C. Exceeding 500µA may cause output regulation loss or increased drift, and is outside the device's characterized operating range.
Does MAX6023EBT41 require an external output capacitor for stability?
No, MAX6023EBT41 does not require an external output capacitor for stability. It is explicitly characterized as stable with capacitive loads from 0 to 2.2nF, per the Capacitive-Load Stability Range specification. Adding a capacitor may improve transient response under step-load conditions but is unnecessary for basic DC regulation or noise filtering in most applications.
What is the minimum input voltage required for proper operation of MAX6023EBT41?
The minimum input voltage for MAX6023EBT41 is (VOUT + 0.2V) = 4.296V, as specified in the Selector Guide and Electrical Characteristics tables. Operation below this voltage results in loss of regulation; the device remains functional but cannot maintain 4.096V output accuracy or specified dropout performance.
How does the supply current of MAX6023EBT41 vary with input voltage?
MAX6023EBT41 exhibits a supply current variation of ≤0.8µA/V across its input voltage range (4.296V to 12.6V), meaning total supply current stays within 27–35µA. This near-constant current draw-unlike shunt references-maximizes battery efficiency and minimizes input rail interaction in low-power systems.
Is MAX6023EBT41 compatible with standard reflow soldering processes?
Yes, MAX6023EBT41 supports JEDEC J-STD-020A-compliant reflow profiles (IR/VPR and convection), including preheating. Hand soldering and wave soldering are explicitly prohibited per the Absolute Maximum Ratings section. Peak bump temperature must not exceed +300°C for 10 seconds to ensure UCSP reliability.
