Analog Devices Inc./Maxim Integrated MAX6007BEUR-T

Overview

MAX6007BEUR-T from Maxim Integrated is a precision 2.048V shunt voltage reference in a 3-pin SOT23 package, designed for ultra-low-power operation with guaranteed <1µA minimum operating current, 0.5% initial accuracy, and 75ppm/°C temperature coefficient over -40°C to +85°C. It serves as a stable reference in battery-powered meters and precision A/D converters where low quiescent current and compact size are critical.

For engineers reviewing the MAX6007BEUR-T datasheet, MAX6007BEUR-T pinout, MAX6007BEUR-T application, or MAX6007BEUR-T equivalent, key selection factors include its 2.048V output voltage, 0.5% initial tolerance, 75ppm/°C TC, SOT23-3 package footprint, and compatibility with 0.01µF output bypassing - all essential for low-power analog signal conditioning and data acquisition systems.

Technical Context

The MAX6007BEUR-T is a two-terminal bandgap shunt reference using laser-trimmed thin-film resistors to achieve factory-set 2.048V output. Its internal architecture delivers stable reverse breakdown behavior with dynamic impedance of 1.8Ω (1.2µA–2mA) and low-frequency noise of 50µV_P-P (0.1Hz–10Hz).

It operates across 1.2µA to 2mA cathode current, with reverse breakdown change ≤2.3mV over that range and thermal hysteresis ≤200ppm. The device requires external bias via a pull-up resistor and 0.01µF GND bypass at OUT to ensure stability under load transients.

FAQ

What is the guaranteed minimum operating current for MAX6007BEUR-T?

The MAX6007BEUR-T guarantees a minimum operating current of 1.0µA (typical) with VR change <0.2% from its 2.048V nominal value. This ultra-low threshold enables use in energy-harvesting circuits and multi-year battery applications where supply current must remain below 2µA. The MAX6007BEUR-T remains stable down to this level when properly bypassed with ≥0.01µF to GND.

Does MAX6007BEUR-T require an external capacitor, and if so, what value?

Yes, the MAX6007BEUR-T requires a minimum 0.01µF capacitor from OUT to GND for stability, as specified in the Typical Applications section. This capacitor mitigates transient overshoot during load or supply steps and reduces low-frequency noise. Larger values (e.g., 0.1µF) may further improve PSRR but do not degrade performance. The MAX6007BEUR-T's internal design relies on this external bypass for predictable startup and regulation behavior.

What is the temperature coefficient specification for MAX6007BEUR-T, and over what range is it guaranteed?

The MAX6007BEUR-T has a maximum temperature coefficient of 75ppm/°C, guaranteed over the full industrial temperature range of -40°C to +85°C. This value is measured using the "box" method (TC = (V_MAX – V_MIN) / (T_MAX – T_MIN)). At 2.048V output, this corresponds to a worst-case drift of ±6.3mV across the range - a key parameter verified per unit during production test.

Can MAX6007BEUR-T be used as a direct replacement for LM4040B20?

No, MAX6007BEUR-T is not a direct replacement for LM4040B20. While both are 2.048V shunt references in SOT23-3, the LM4040B20 has ±0.2% initial accuracy and 50ppm/°C TC, whereas MAX6007BEUR-T offers ±0.5% accuracy and 75ppm/°C TC. Additionally, the MAX6007BEUR-T's 1µA minimum current is significantly lower than LM4040B20's 45µA minimum. System validation is required before substitution.

What is the purpose of the IC pin (Pin 3) on MAX6007BEUR-T?

The IC pin (Pin 3) on MAX6007BEUR-T is an internally connected test point used during wafer sort and final test. It is not functional in normal operation and must be left unconnected or tied to GND - either configuration yields identical electrical performance. No external circuitry should drive or load this pin, as it provides no user-accessible signal or control function in the MAX6007BEUR-T.
