Product details
Overview
MAX6069BBAWS+T from Analog Devices is a precision 2.048V, 0.5% initial accuracy, 50ppm/°C temperature coefficient shunt voltage reference in a 0.88mm × 1.16mm 4-bump wafer-level package (WLP), operating from 1μA to 2mA and rated for -40°C to +125°C - ideal for portable sensors and loop-powered instrumentation requiring ultra-low power and high stability.
For engineers reviewing the MAX6069BBAWS+T datasheet, MAX6069BBAWS+T pinout, MAX6069BBAWS+T application, or MAX6069BBAWS+T equivalent, this page delivers verified electrical specs, validated WLP terminal mapping, real-world use cases in 4mA–20mA transmitters and precision ADCs, and two confirmed alternative references with documented performance trade-offs.
Technical Context
The MAX6069BBAWS+T implements a two-terminal shunt bandgap architecture with on-chip laser-trimmed thin-film resistors, delivering stable 2.048V output across its full -40°C to +125°C junction range. Its reverse dynamic impedance remains ≤1.8Ω from 1.2μA to 2mA, enabling low-noise operation with <50µVp-p (0.1Hz–10Hz) and minimal current-induced voltage shift (≤2.3mV over 200μA–2mA).
Designed for space-constrained systems, it uses a 4-bump WLP with internal A1/B1 shorted (OUT) and A2/B2 shorted (GND), eliminating routing complexity while maintaining thermal hysteresis <200ppm and long-term drift <150ppm over 1000 hours at +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.048V ±0.5% at +25°C - ensures accurate scaling for 12-bit DACs and 10-bit ADCs without calibration. |
| Initial Accuracy | ±0.5% - enables single-point trimming in portable meters and sensor front-ends. |
| Temp Coefficient | 50ppm/°C (−40°C to +85°C), 75ppm/°C (−40°C to +125°C) - defines worst-case drift in industrial ambient conditions. |
| Min Operating Current | 1.0μA max - supports battery life >10 years in always-on IoT nodes drawing <10μA system current. |
| Reverse Dynamic Impedance | 1.8Ω (1.2μA–2mA) - minimizes load regulation error in high-impedance sensing circuits. |
| Low-Frequency Noise | 50µVp-p (0.1Hz–10Hz) - preserves resolution in sub-16-bit precision measurement paths. |
| Package | 0.88mm × 1.16mm, 4-bump WLP - fits within 1.0mm² PCB area, compatible with 0201 footprint constraints. |
Pinout & Package
MAX6069BBAWS+T uses a 4-bump wafer-level package (WLP) with top-side bump layout: A1 and B1 are internally shorted OUT terminals; A2 and B2 are internally shorted GND terminals. This dual-bump configuration improves thermal and current-handling symmetry versus single-terminal WLPs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | OUT | Main output node; must be biased via external pull-up resistor to voltage >2.048V and bypassed with ≥0.01µF capacitor to GND. |
| A2 | GND | Reference ground return; electrically tied to B2; requires low-inductance connection to system ground plane. |
| B1 | OUT | Internally shorted to A1 - provides redundant current path and improved thermal dissipation under 2mA load. |
| B2 | GND | Internally shorted to A2 - enhances ground current sharing and reduces package thermal resistance (θJA = 102.59°C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low operating current | Guaranteed ≤1.0μA minimum - extends coin-cell battery life in wireless sensor nodes beyond 5 years. |
| Laser-trimmed accuracy | 0.5% initial tolerance at +25°C - eliminates post-assembly calibration in cost-sensitive portable instruments. |
| Low thermal hysteresis | <200ppm after −40°C/+125°C cycling - maintains repeatability in field-deployed environmental monitors. |
| Stable low-frequency noise | 50µVp-p (0.1Hz–10Hz) - avoids signal corruption in high-gain amplifier stages feeding 24-bit ΣΔ ADCs. |
| Compact WLP footprint | 0.88mm × 1.16mm - enables placement directly adjacent to ADC input pins, minimizing trace inductance and EMI pickup. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6007BASA+ | Same 2.048V output, 0.5% accuracy, but in SO-8 package (3.9mm × 4.9mm); higher θJA (140°C/W); 10µA min current. | Requires larger PCB area; unsuitable for wearables or implantables; better suited for board-level test equipment. | Select when board space permits and higher drive capability (up to 15mA) is needed. |
| LM4040C20IDCKR | 2.048V, 0.5% accuracy, SOT-23-3 package; 60ppm/°C TC; 60µA min current; 75µVp-p noise. | Higher quiescent current limits battery life; larger noise degrades 16-bit+ measurements; less stable over temperature cycling. | Select only if legacy compatibility or SOT-23 assembly infrastructure exists and ultra-low power is not critical. |
Compared with MAX6069BBAWS+T, MAX6007BASA+ trades miniaturization for higher current drive and thermal margin, while LM4040C20IDCKR sacrifices low-noise performance and sub-µA operation for broader manufacturing availability - making MAX6069BBAWS+T optimal for next-gen compact, battery-critical systems.

FAQ
What is the guaranteed minimum operating current for MAX6069BBAWS+T?
The MAX6069BBAWS+T guarantees a maximum minimum operating current of 1.0μA, measured as the lowest current at which the reverse breakdown voltage changes by less than 0.2% from its value at 1.2μA. This specification is tested across the full −40°C to +125°C temperature range and ensures reliable startup and regulation in energy-harvesting and coin-cell applications where supply current is tightly constrained. The MAX6069BBAWS+T maintains regulation down to this level without oscillation or dropout.
Does MAX6069BBAWS+T support operation up to +125°C junction temperature?
Yes, MAX6069BBAWS+T is fully specified and guaranteed over an operating temperature range of −40°C to +125°C. Its temperature coefficient is characterized at 75ppm/°C over this extended range, and all key parameters - including output voltage accuracy, dynamic impedance, and noise - are validated per the datasheet's Electrical Characteristics tables. The WLP package's thermal resistance (θJA = 102.59°C/W on a four-layer board) enables safe operation at full rating when mounted on standard FR-4 PCBs with adequate copper pour.
How is the pinout configured on the MAX6069BBAWS+T WLP package?
The MAX6069BBAWS+T uses a 4-bump WLP with A1 and B1 internally shorted to form the OUT terminal, and A2 and B2 internally shorted to form the GND terminal. This dual-bump topology improves current sharing and thermal symmetry. The top-side marking "+AP" identifies the B-grade 2.048V variant. No external connections are required between bumps - A1/B1 serve as one output node, A2/B2 as one ground node - simplifying layout and reducing parasitic inductance in high-precision analog paths.
Can MAX6069BBAWS+T replace LM4040 in existing designs?
MAX6069BBAWS+T can functionally replace LM4040 in shunt reference roles but requires PCB layout revision due to its 4-bump WLP versus LM4040's SOT-23-3. While both provide 2.048V output and 0.5% accuracy, MAX6069BBAWS+T operates down to 1μA (vs. LM4040's 60μA minimum), offers lower noise (50µVp-p vs. 75µVp-p), and tighter tempco (50ppm/°C vs. 60ppm/°C). However, its WLP footprint and dual-output/dual-ground bump structure demand new land patterns and stencil design.
What is the reverse dynamic impedance of MAX6069BBAWS+T and why does it matter?
The reverse dynamic impedance of MAX6069BBAWS+T is 1.8Ω over the 1.2μA to 2mA operating range. This low value directly determines load regulation error: for example, a 100μA change in shunt current causes only 180μV output shift. In precision sensor interfaces and ratiometric ADC systems, this ensures stable reference voltage despite varying load currents - critical for maintaining measurement accuracy in battery-powered devices where supply current fluctuates with RF transmission or sensor activation cycles. The MAX6069BBAWS+T's impedance remains flat across frequency and temperature, unlike discrete Zener alternatives.
