Product details
Overview
MAX6069CBAWS+T from Analog Devices is a precision 2.500V, 0.5% initial accuracy, 50ppm/°C temperature coefficient shunt voltage reference in a 4-bump wafer-level package (WLP), operating from 1μA to 2mA and supporting portable sensors, loop-powered transmitters, and high-resolution ADCs.
For engineers reviewing the MAX6069CBAWS+T datasheet, MAX6069CBAWS+T pinout, MAX6069CBAWS+T application, or MAX6069CBAWS+T equivalent, key selection criteria include ultra-low operating current (<1μA min), 0.88mm × 1.16mm WLP footprint, ±2.5mV reverse breakdown change over 1.2μA–2mA, 2Ω dynamic impedance, and thermal hysteresis <200ppm.
Technical Context
The MAX6069CBAWS+T is a two-terminal shunt bandgap reference with laser-trimmed thin-film resistors enabling 0.5% factory-set output accuracy at 2.500V. It operates across -40°C to +125°C with guaranteed 50ppm/°C TC over -40°C to +85°C and 75ppm/°C up to +125°C.
Its low-frequency noise is 60µVp-p (0.1Hz–10Hz), reverse dynamic impedance is 2Ω (1.2μA–2mA), and long-term drift is 150ppm after 1000h at +25°C. The device requires no external biasing beyond a pull-up resistor and ≥0.01µF OUT-to-GND capacitor.

Applications
| Portable Sensors | Precision Regulators |
|---|---|
Use Scenario: Battery-powered gas sensor node measuring ppm-level CO using electrochemical cell. IC Role / Device Role / Timing Role: Shunt reference providing stable 2.500V excitation and ADC reference for analog front-end. Use Value: 0.5μA min current draw extends 10-year battery life; 50ppm/°C TC prevents calibration drift across outdoor temperature swings. | Use Scenario: Low-power LDO feedback network requiring precise 2.5V setpoint in medical infusion pump. IC Role / Device Role / Timing Role: Precision voltage reference setting output of adjustable LDO via resistor divider. Use Value: 0.5% initial accuracy eliminates manual trim; WLP package allows placement directly adjacent to LDO die for minimal trace inductance. |
| 4mA–20mA Loop-Powered Sensors | A/D and D/A Converters |
Use Scenario: Two-wire pressure transmitter powered from 4–20mA loop with onboard signal conditioning. IC Role / Device Role / Timing Role: Shunt reference supplying stable bias to op-amps and ADC in loop-powered architecture.

IC Role / Device Role / Timing Role: Primary reference for both ADC and DAC in dual-conversion architecture. Use Value: Matched 2.500V output enables ratiometric measurement; 150ppm long-term drift limits recalibration to once per 3 years. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6008CBA+T | Same 2.5V output, 0.5% accuracy, but 100ppm/°C TC and SOT23-3 package (2.9mm × 1.6mm) | Higher TC limits use in wide-temperature industrial nodes; larger package constrains ultra-compact designs | Select when board space permits and cost sensitivity outweighs thermal performance needs |
| LM4040C25IDCKR | 2.5V, 0.5% accuracy, 100ppm/°C TC, SC70-3 package (2.0mm × 1.25mm), 60µA min current | 60× higher minimum current precludes energy-harvesting or nanoamp sensor use; SC70 larger than WLP | Select for legacy designs already using SC70 footprints and where supply current >60µA is available |
Compared with MAX6008CBA+T and LM4040C25IDCKR, the MAX6069CBAWS+T delivers superior thermal stability (50ppm/°C vs. 100ppm/°C), 60× lower minimum operating current, and a 75% smaller footprint-making it optimal for next-generation miniaturized, battery-critical systems.

FAQ
What is the exact output voltage tolerance of the MAX6069CBAWS+T at +25°C?
The MAX6069CBAWS+T has a nominal output voltage of 2.500V with an initial accuracy of ±0.5% at +25°C, corresponding to a guaranteed range of 2.4875V to 2.5125V per the Electrical Characteristics table. This tolerance is factory-laser-trimmed and applies before thermal or long-term drift effects.
Does the MAX6069CBAWS+T require an external capacitor, and if so, what value is recommended?
Yes, the MAX6069CBAWS+T requires a minimum 0.01µF capacitor between OUT and GND to ensure stability and reduce noise. The datasheet specifies this capacitance for proper transient response and low-frequency noise suppression; larger values (e.g., 0.1µF) further improve step-load immunity without compromising startup time.
What is the maximum operating current rating for the MAX6069CBAWS+T, and how does it affect power dissipation?
The MAX6069CBAWS+T supports a maximum reverse current of 20mA. At 2.5V output, this yields up to 50mW continuous power dissipation. On a multilayer board, derating begins above +70°C at 9.75mW/°C, limiting usable power at +125°C ambient to ~24mW - well within its 780mW absolute max rating.
How does the pin configuration of the MAX6069CBAWS+T differ from standard 3-pin shunt references?
The MAX6069CBAWS+T uses a 4-bump WLP with two OUT (A1/B1) and two GND (A2/B2) terminals, all internally shorted in pairs. This dual-terminal layout reduces parasitic inductance and improves thermal symmetry versus single-pin SOT23 or SC70 packages - critical for noise-sensitive precision applications.
Can the MAX6069CBAWS+T be used in automotive under-hood applications?
Yes, the MAX6069CBAWS+T is rated for -40°C to +125°C operation and qualified per JEDEC standards for reliability. Its 50ppm/°C tempco over -40°C to +85°C and 75ppm/°C up to +125°C, combined with 200ppm thermal hysteresis, make it suitable for engine control modules, battery monitoring, and other under-hood subsystems requiring stable 2.5V referencing.
