Product details
Overview
MAX6069CAAWS+T from Analog Devices is a precision 2.500V, 0.2% initial accuracy, ultra-low-power shunt voltage reference in a 4-bump wafer-level package (WLP), operating from 1μA to 2mA with 20ppm/°C max temperature coefficient over –40°C to +85°C - ideal for portable sensors and high-precision A/D converters.
For engineers reviewing the MAX6069CAAWS+T datasheet, MAX6069CAAWS+T pinout, MAX6069CAAWS+T application, or MAX6069CAAWS+T equivalent, this page delivers verified electrical specs, WLP terminal mapping, real-world use cases, and validated alternative options for low-current, space-constrained analog signal chains.
Technical Context
The MAX6069CAAWS+T is a two-terminal shunt bandgap reference using on-chip laser-trimmed thin-film resistors to achieve 0.2% output voltage accuracy at 2.500V. It functions as a precision voltage node by sinking current through an external bias resistor, requiring no supply rail - only a pull-up to a higher potential.
Its design targets ultra-low quiescent current operation (min 0.5μA, typ 1.0μA), low-frequency noise (60µVp-p, 0.1Hz–10Hz), and stable dynamic impedance (2Ω, 1.2μA–2mA), enabling reliable performance in battery-powered sensor front-ends and loop-powered transmitters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±0.005V (0.2% initial accuracy) - sets precise reference level for 12-bit+ ADCs without calibration. |
| Temp Coefficient | 20ppm/°C max (–40°C to +85°C) - contributes ≤±0.5mV drift across industrial temp range. |
| Min Operating Current | 0.5μA - enables operation from microamp-level bias sources, e.g., high-impedance sensor interfaces. |
| Reverse Dynamic Impedance | 2Ω (1.2μA–2mA) - ensures stable regulation under varying load/supply conditions with minimal voltage shift. |
| Low-Frequency Noise | 60µVp-p (0.1Hz–10Hz) - supports high-resolution measurements in precision metering applications. |
| Operating Temp Range | –40°C to +125°C - qualified for extended industrial environments; specified accuracy applies to –40°C to +85°C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6008AESA+ | Same 2.5V output, 0.2% accuracy, but SO-8 package (3.9mm × 4.9mm); 25ppm/°C TC; min current 10μA. | Requires larger PCB area; unsuitable for ultra-miniaturized designs; higher current draw limits battery life. | Select when board space permits and legacy SO-8 layout reuse is prioritized over size/power. |
| ADR3425ARJZ-R7 | 2.5V, 0.1% accuracy, 10ppm/°C TC, SOT-23-3; min current 100μA; 65µVp-p noise. | Higher accuracy and lower TC, but 100× higher min current; incompatible WLP footprint. | Select when ultimate precision outweighs power/size constraints and SOT-23 is acceptable. |
Compared with MAX6069CAAWS+T, MAX6008AESA+ trades miniaturization and ultra-low current for package familiarity, while ADR3425ARJZ-R7 offers tighter accuracy and TC at the cost of 100× higher minimum operating current - making MAX6069CAAWS+T optimal for space- and energy-constrained portable instrumentation.

FAQ
What is the output voltage tolerance of the MAX6069CAAWS+T at room temperature?
The MAX6069CAAWS+T has a guaranteed output voltage of 2.500V with ±0.005V (±0.2%) initial accuracy at +25°C, as confirmed by 100% production testing and laser trimming of on-chip thin-film resistors per the official Analog Devices datasheet.
Can the MAX6069CAAWS+T operate from a 3.0V supply in a shunt configuration?
Yes - the MAX6069CAAWS+T operates as a two-terminal shunt reference and requires only a bias resistor connecting its OUT terminal to a supply ≥2.5V. With a 3.0V supply and appropriate RBIAS, it sinks 1.2μA–2mA while maintaining 2.500V regulation, per its Electrical Characteristics table.
Does the MAX6069CAAWS+T require an external capacitor, and if so, what value?
Yes - the MAX6069CAAWS+T requires a minimum 0.01µF capacitor from OUT to GND for stability, as specified in the Applications Information section. Larger values (e.g., 0.1µF) improve transient response in step-load applications but do not affect DC accuracy.
What is the maximum operating temperature range for the MAX6069CAAWS+T?
The MAX6069CAAWS+T is rated for operation from –40°C to +125°C. However, its guaranteed 0.2% initial accuracy and 20ppm/°C temperature coefficient apply over the extended industrial range of –40°C to +85°C, per the Electrical Characteristics table.
How does the dual-OUT/dual-GND pin configuration of the MAX6069CAAWS+T improve performance?
The MAX6069CAAWS+T uses redundant A1/B1 (OUT) and A2/B2 (GND) bumps to reduce package parasitic inductance and improve thermal symmetry. This lowers dynamic impedance variation and enhances PSRR - critical for low-noise, high-precision shunt reference operation in compact WLP layouts.
