Product details
Overview
MAX6023EBT41+T from Maxim Integrated is a precision, low-power, low-dropout series-mode voltage reference in a 5-bump UCSP package (1.0mm × 1.5mm × 0.3mm), 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 quiescent current, and maintains stability with up to 2.2nF capacitive load - ideal for high-resolution data acquisition systems requiring tight reference stability.
For engineers reviewing the MAX6023EBT41+T datasheet, MAX6023EBT41+T pinout, MAX6023EBT41+T application, or MAX6023EBT41+T equivalent, key selection considerations include its 4.096V output optimized for 12-bit ADCs, 100mV dropout at 500µA, 160µV/V line regulation, and UCSP footprint constraints for space-constrained portable instrumentation.
Technical Context
The MAX6023EBT41+T uses a proprietary curvature-corrected bandgap core with laser-trimmed thin-film resistors to achieve <30ppm/°C drift and ±0.20% initial accuracy. Its series-mode architecture enables bidirectional output current (±500µA) without external compensation.
It features internally compensated stability across 0–2.2nF load capacitance, 0.8µA/V supply current variation with input voltage, and turn-on settling to 0.1% of final value in 160µs (COUT = 50pF). Input voltage range is strictly (4.296V to 12.6V), defined by the VOUT + 0.2V minimum.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.20% at +25°C - matches standard 12-bit DAC/ADC full-scale reference points. |
| Initial Accuracy | ±0.20% - eliminates need for system-level calibration in precision measurement front-ends. |
| Tempco | ≤30ppm/°C - ensures <±1.2mV drift over –40°C to +85°C, critical for industrial sensor signal chains. |
| Dropout Voltage | 100mV at 500µA load - supports operation from 4.296V input, enabling single-cell Li-ion or 5V rail margin. |
| Quiescent Current | 35µA max - extends battery life in handheld meters and wireless sensor nodes beyond 10 years at µA-level sleep currents. |
| Line Regulation | 160µV/V max - limits output shift to <1.3mV over full 4.296V–12.6V input range, easing LDO selection. |
| Capacitive Load Stability | 0–2.2nF - allows direct connection to ADC reference inputs without destabilizing oscillation risk. |
Pinout & Package
MAX6023EBT41+T uses a 5-bump wafer-level chip-scale package (UCSP) measuring 1.0mm × 1.5mm × 0.3mm, with bumps on the bottom side. The package requires JEDEC J-STD-020A-compliant reflow profiles; hand/wave soldering is prohibited.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A3 | I.C. | Internally connected; must remain unconnected on PCB - no routing or vias allowed. |
| A2 | GND | Reference ground return path; requires low-inductance connection to system AGND plane. |
| B1 | OUT | 4.096V precision reference output; drives ADC/DAC reference inputs or op-amp feedback networks. |
| B3 | IN | Input supply pin; must be decoupled with ≥0.1µF ceramic capacitor placed within 2mm of bump. |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Stable with 0–2.2nF load capacitance - eliminates BOM cost and board area for reference bypass caps. |
| Low dropout at full load | 100mV dropout at 500µA sink/source - enables use with low-headroom supplies like buck converters near VOUT. |
| Supply current independence | Only 0.8µA/V variation with input voltage - simplifies power budgeting across varying battery states. |
| Ultra-small footprint | 1.0mm × 1.5mm UCSP - saves >70% board area vs. SOT23, critical for wearable and implantable devices. |
| High PSRR | 77dB ripple rejection at 120Hz - suppresses switching regulator noise coupling into precision analog circuits. |
Applications

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 output, ±0.1% initial accuracy, 30ppm/°C tempco, SOT23-5 package (2.9mm × 1.6mm), 4.5µA typical supply current. | Larger footprint and lower quiescent current; better for ultra-low-power sleep modes but less suitable for height-constrained designs. | Select when board area is less constrained than height, and sub-µA sleep current dominates power budget. |
| REF3340AIDBVR | 4.096V output, ±0.2% initial accuracy, 50ppm/°C tempco, SOT23-3 package, 3.9µA typical supply current, 150mV dropout. | Higher tempco and dropout; smaller 3-pin SOT23 but lacks load-current sourcing capability. | Select for cost-sensitive, non-precision applications where 50ppm/°C drift is acceptable and sourcing current is not required. |
Compared with ADR3440BRJZ-R7 and REF3340AIDBVR, MAX6023EBT41+T uniquely combines UCSP's 1.0mm × 1.5mm footprint, ±0.20% accuracy, 30ppm/°C tempco, and ±500µA output drive - making it optimal for miniaturized, high-accuracy data loggers and portable instrumentation where board height and reference stability are co-constrained.

FAQ
What is the minimum input voltage required for stable operation of MAX6023EBT41+T?
The MAX6023EBT41+T requires a minimum input voltage of VOUT + 0.2V = 4.296V for guaranteed specifications. Operation below this voltage may result in degraded line regulation, increased dropout, or failure to maintain 4.096V output. The absolute maximum input is 12.6V, and the device is rated for continuous operation across –40°C to +85°C ambient.
Can MAX6023EBT41+T drive an ADC reference input directly without an external capacitor?
Yes, MAX6023EBT41+T is stable with 0–2.2nF capacitive loads and does not require an external output capacitor for basic operation. However, adding a 100pF–1nF ceramic capacitor close to the OUT pin improves transient response during fast load steps - especially beneficial when driving successive-approximation ADCs with dynamic reference current demands.
How does the supply current of MAX6023EBT41+T vary with input voltage?
MAX6023EBT41+T exhibits only 0.8µA/V variation in supply current across its operating input range (4.296V to 12.6V), with a maximum quiescent current of 35µA. This near-constant current draw simplifies power budgeting in battery-powered systems where VIN declines over time, unlike shunt references that waste current continuously.
Is MAX6023EBT41+T compatible with standard reflow soldering processes?
MAX6023EBT41+T requires strict adherence to JEDEC J-STD-020A reflow profiles (paragraph 7.6, Table 3), including preheating. Hand soldering and wave soldering are explicitly prohibited due to UCSP's thermal sensitivity. Peak bump temperature must not exceed +300°C for 10 seconds, and thermal profile validation is mandatory before production ramp.
What is the maximum load current MAX6023EBT41+T can source or sink while maintaining specification?
MAX6023EBT41+T is specified to source or sink up to ±500µA while maintaining output voltage accuracy within ±0.2% and dropout ≤200mV. At 500µA load, dropout is guaranteed ≤100mV. Exceeding ±500µA may cause output deviation beyond datasheet limits or thermal instability in the UCSP package.
