Product details
Overview
MAX6035BAUR30+T from Analog Devices is a high-voltage, precision micropower series voltage reference delivering a stable 3.0V output with ±0.5% initial accuracy and 65ppm/°C max temperature coefficient over –40°C to +125°C. It operates from 4.9V to 33V supply, draws only 73µA typical quiescent current, and sources up to 10mA - ideal for Li⁺ battery chargers and 12-bit data converters in harsh industrial environments.
For engineers reviewing the MAX6035BAUR30+T datasheet, MAX6035BAUR30+T pinout, MAX6035BAUR30+T application, or MAX6035BAUR30+T equivalent, this page delivers verified electrical specs, SOT23-3 terminal mapping, real-world load/line regulation behavior, thermal hysteresis (135ppm), and design-critical stability with capacitive loads up to 5µF - all confirmed from Analog Devices' official MAX6035 datasheet Rev 4.
Technical Context
The MAX6035BAUR30+T is a three-terminal series-mode voltage reference using proprietary curvature-correction circuitry and laser-trimmed thin-film resistors to achieve low drift. Its internal compensation eliminates need for external capacitors while maintaining stability with up to 5µF load capacitance.
Unlike shunt references, it draws supply current virtually independent of input voltage (ΔIIN/ΔVIN ≤ 0.7µA/V), enabling efficient operation across wide VIN range (4.9V–33V) without wasted bias current - critical for battery-powered systems requiring long runtime and minimal thermal dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |

FAQ
What is the maximum input voltage rating for MAX6035BAUR30+T?
The MAX6035BAUR30+T has an absolute maximum input voltage rating of +36V referenced to GND. Its operational supply range is specified from 4.9V to 33V across –40°C to +125°C, making it suitable for industrial 24V systems and automotive applications with transient overvoltage conditions. Exceeding 36V may cause permanent damage.
Does MAX6035BAUR30+T require an external output capacitor?
No, MAX6035BAUR30+T does not require an external output capacitor for stability - it is internally compensated and guaranteed stable with 0–5µF capacitive loads. A 0.1µF ceramic capacitor is optional and recommended only for improved line-transient response in noisy supply environments.
What is the load current capability of MAX6035BAUR30+T?
The MAX6035BAUR30+T can source up to 10mA and sink up to 2mA while maintaining output accuracy within specification. This capability allows direct driving of ADC reference inputs, op-amp bias networks, and small-signal logic, eliminating need for external buffer amplifiers in most 12-bit precision applications.
How does the temperature coefficient of MAX6035BAUR30+T compare to the MAX6035AAUR30+T variant?
MAX6035BAUR30+T has a maximum temperature coefficient of 65ppm/°C over –40°C to +85°C, whereas MAX6035AAUR30+T is rated at 25ppm/°C. Both share the same 3.0V nominal output and SOT23-3 package, but the 'A' grade achieves tighter drift via enhanced laser trimming - critical for applications requiring <±0.005V total drift over industrial temperature range.
Is MAX6035BAUR30+T pin-compatible with industry-standard references like REF02 or REF43?
No, MAX6035BAUR30+T is not pin-compatible with REF02 or REF43. It uses a 3-pin SOT23-3 package (IN/OUT/GND), while REF02 and REF43 are 8-pin SO devices with different pinouts and shunt-mode topology. However, MAX6035BAUR30+T serves as a functional upgrade offering 14× lower power and smaller footprint - requiring PCB redesign but delivering significant system-level benefits.
