Analog Devices Inc./Maxim Integrated MAX6008AEUR/V+T

Overview

MAX6008AEUR/V+T from Maxim Integrated is a precision 2.5V two-terminal shunt voltage reference in a 3-pin SOT23 package, featuring 0.2% initial accuracy, 30ppm/°C temperature coefficient over -40°C to +85°C, <1µA guaranteed operating current, and AEC-Q100 qualification for automotive use. It serves as a low-power, high-stability reference in battery-powered sensor signal chains and precision ADC biasing.

For engineers reviewing the MAX6008AEUR/V+T datasheet, MAX6008AEUR/V+T pinout, MAX6008AEUR/V+T application, or MAX6008AEUR/V+T equivalent, this page delivers verified electrical specs, automotive-grade thermal stability data, SOT23 terminal mapping, and validated alternatives for design-in and BOM replacement decisions.

Technical Context

The MAX6008AEUR/V+T implements a laser-trimmed series bandgap core with on-chip thin-film resistors, delivering stable 2.500V output at 1.2µA test current. Its two-terminal architecture requires external bias resistor (R_Bias) and 0.01µF minimum output capacitance for stability.

It operates across 1µA–2mA load current range with <2.5mV reverse breakdown change from 200µA to 2mA, 2Ω typical dynamic impedance, and 60µV_P-P low-frequency noise (0.1Hz–10Hz), enabling high-resolution analog measurement systems.

FAQ

What is the maximum operating current for MAX6008AEUR/V+T?

The MAX6008AEUR/V+T supports a continuous operating current range from 1.0µA minimum to 2mA maximum. At 2mA, its reverse breakdown voltage changes by ≤2.5mV versus the 1.2µA test point, and power dissipation remains within safe limits for the SOT23 package at ambient temperatures up to +85°C. This wide current range allows flexible bias resistor selection in varying supply and load conditions.

Does MAX6008AEUR/V+T require an external capacitor?

Yes, MAX6008AEUR/V+T requires a minimum 0.01µF capacitor connected between OUT (pin 1) and GND (pin 2). This capacitor stabilizes the reference against load and supply transients, reduces noise, and ensures proper startup behavior. Larger values (e.g., 0.1µF) further improve transient response in applications with step-load changes, such as multiplexed sensor readouts.

Is MAX6008AEUR/V+T pin-compatible with other MAX600x variants?

Yes, all MAX6006–MAX6009 variants in the 3-pin SOT23 package share identical pinout: pin 1 = OUT, pin 2 = GND, pin 3 = IC (no-connect). The MAX6008AEUR/V+T is functionally and physically interchangeable with MAX6006AEUR+T, MAX6007AEUR+T, and MAX6009AEUR+T in the same package - only the output voltage and top-mark differ.

What does the "/V" suffix indicate in MAX6008AEUR/V+T?

The "/V" suffix in MAX6008AEUR/V+T denotes AEC-Q100 qualification per Grade 3 (-40°C to +85°C), including stress testing for automotive reliability (HTOL, TCT, ESD, etc.). This distinguishes it from industrial-grade MAX6008AEUR+T and confirms suitability for under-hood and cabin electronics where extended temperature operation and failure-rate requirements apply.

Can MAX6008AEUR/V+T replace LM4040 in existing designs?

MAX6008AEUR/V+T can replace LM4040 in many shunt reference applications due to identical 3-pin SOT23 footprint and compatible biasing, but requires verification of current compliance: LM4040 typically needs ≥45µA, while MAX6008AEUR/V+T operates down to 1µA. Its tighter 0.2% accuracy and 30ppm/°C TC offer measurable improvement in precision systems, especially where AEC-Q100 compliance is needed.
