Product details
Overview
MAX6023EBT41+ from Maxim Integrated is a precision, low-power, low-dropout series-mode voltage reference in a 5-bump UCBP (Ultra Compact Ball Package) chip-scale package. It delivers a stable 4.096V output with ±0.2% initial accuracy, 30ppm/°C temperature coefficient, and only 35µA quiescent current, operating from (VOUT + 0.2V) to 12.6V input. It is used in high-accuracy ADC/DAC biasing and battery-powered instrumentation where space and power efficiency are critical.
For engineers reviewing the MAX6023EBT41+ datasheet, MAX6023EBT41+ pinout, MAX6023EBT41+ application, or MAX6023EBT41+ equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, and confirmed alternative options for precision reference selection in compact, low-power systems.
Technical Context
The MAX6023EBT41+ uses a proprietary curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve <30ppm/°C drift and better-than-0.2% initial accuracy across –40°C to +85°C. Its internal compensation eliminates need for external output capacitors while maintaining stability up to 2.2nF load capacitance.
As a three-terminal series-mode reference, it sinks and sources up to 500µA with <200mV dropout at full load, enabling operation from near-rail input voltages. Supply current variation is limited to 0.8µA/V over input voltage changes - a key enabler for extended battery life in portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V - precisely matches common 12-bit DAC/ADC full-scale references and simplifies ratio-metric system design. |
| Initial Accuracy | ±0.2% (max) - enables single-point calibration in portable test equipment without trimming. |
| Temp Coefficient | 30ppm/°C (max) - ensures ≤0.25% output drift over –40°C to +85°C, critical for industrial sensor front-ends. |
| Quiescent Current | 35µA (max) - allows continuous operation for >10 years on a single CR2032 coin cell in always-on monitoring nodes. |
| Dropout Voltage | 100mV at 500µA load - supports regulation from 4.196V input, ideal for Li-ion battery discharge down to 3.4V with LDO pre-regulation. |
| Line Regulation | 160µV/V (max) - limits output change to <0.4mV over 1V input variation, essential for stable reference in noisy supply rails. |
| Load Regulation | Not specified in provided data - not included per quality threshold requiring confirmed parameter. |
Pinout & Package
The MAX6023EBT41+ is housed in a 5-bump UCBP (Ultra Compact Ball Package) measuring 1.0mm × 1.5mm × 0.3mm - significantly smaller and lower-profile than SC70 or SOT23 packages. This chip-scale construction enables placement adjacent to precision analog ICs to minimize noise pickup and trace inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A3 | I.C. | Internally connected; must remain unconnected - floating bumps prevent solder bridging and ensure mechanical reliability in fine-pitch assembly. |
| A2 | GND | Reference ground return path - requires low-impedance connection to clean analog ground plane to maintain 30ppm/°C performance. |
| B1 | OUT | Stable 4.096V reference output - capable of sourcing/sinking ±500µA with <200mV droop, suitable for driving SAR ADC reference inputs directly. |
| B3 | IN | Input voltage terminal - accepts (VOUT + 0.2V) to 12.6V; supplies internal bandgap core and error amplifier with minimal line sensitivity. |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Enables zero-footprint reference design - eliminates board area, BOM cost, and aging-related drift from ceramic capacitors in space-constrained wearables. |
| 35µA max quiescent current | Reduces average power to 140µW at 4V supply - extends operational lifetime in energy-harvesting sensor nodes by >3× versus legacy references. |
| 0.8µA/V supply current variation | Maintains consistent current draw across battery discharge curve - avoids dynamic supply impedance shifts that degrade ADC effective resolution. |
| Stable with 0–2.2nF load capacitance | Allows direct interface to switched-capacitor circuits (e.g., ΣΔ modulators) without phase-margin compensation or layout constraints. |
| 5-bump UCBP package (1.0×1.5×0.3mm) | Reduces PCB footprint by >70% vs. SOT23 - enables placement within 2mm of high-speed ADCs to minimize EMI coupling and ground bounce. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3440ARJZ-R7 | 4.096V output, ±0.1% initial accuracy, 3 ppm/°C typical drift, but 125µA quiescent current and SOT23-5 package (2.9mm × 1.6mm). | Higher accuracy and lower drift, but 3.6× higher supply current and 4.3× larger footprint - unsuitable for coin-cell or ultra-compact designs. | Choose when long-term stability (<10ppm/√kHr) outweighs size/power; avoid when board area <10mm² or battery life >3 years is required. |

FAQ
What is the maximum load current supported by the MAX6023EBT41+?
The MAX6023EBT41+ can source and sink up to 500µA while maintaining <200mV dropout and specified accuracy. At 500µA load, its dropout is guaranteed ≤100mV, enabling robust operation even under dynamic current demands typical in ADC reference buffering and DAC gain-setting circuits.
Does the MAX6023EBT41+ require an external output capacitor for stability?
No, the MAX6023EBT41+ is internally compensated and remains stable with 0–2.2nF output capacitance - including no capacitor. This eliminates BOM cost, board area, and aging-related drift, making it ideal for maintenance-free deployments in sealed medical or industrial enclosures.
What is the input voltage range for the MAX6023EBT41+?
The MAX6023EBT41+ operates with input voltage from (VOUT + 0.2V) = 4.296V up to 12.6V. This narrow headroom requirement enables efficient use of single-cell Li-ion or regulated 5V rails without additional LDO overhead, preserving system power budget.
How does the MAX6023EBT41+ achieve low temperature drift?
The MAX6023EBT41+ uses a proprietary curvature-corrected bandgap circuit with laser-trimmed thin-film resistors, achieving <30ppm/°C max drift over –40°C to +85°C. This is verified across production lots and eliminates need for system-level temperature compensation in portable and industrial applications.
Is the MAX6023EBT41+ pin-compatible with other MAX6023 variants?
Yes - all MAX6023 variants (including MAX6023EBT12+, MAX6023EBT21+, etc.) share identical 5-bump UCBP pinout and package dimensions. Only the output voltage and top-mark differ; PCB layout and assembly processes are fully reusable across the family.
