Product details
Overview
MAX6033AAUT30#TG16 from Maxim Integrated is a precision series voltage reference IC delivering a stable 3.000V output with ±0.04% initial accuracy, 7ppm/°C max temperature coefficient, and 200mV max dropout voltage. It operates from -40°C to +125°C and supports up to 15mA load current, making it suitable for high-resolution ADC/DAC biasing in automotive-grade instrumentation.
For engineers reviewing the MAX6033AAUT30#TG16 datasheet, MAX6033AAUT30#TG16 pinout, MAX6033AAUT30#TG16 application, or MAX6033AAUT30#TG16 equivalent, key selection criteria include ultra-low drift (7ppm/°C), low-noise operation (24µVP-P, 0.1Hz–10Hz), capacitive-load stability up to 100µF, and minimal quiescent current (40µA).
Technical Context
The MAX6033AAUT30#TG16 employs bandgap-based architecture with laser-trimmed thin-film resistors and post-package trimming to achieve ±0.04% initial accuracy and 7ppm/°C max tempco over -40°C to +125°C. Its dual-output force-sense topology (OUTF/OUTS) enables precise regulation under varying load and layout conditions.
It functions as a low-dropout series reference with 200mV max dropout at 1mA, 2.7V min input for 3V output, and excellent line regulation (≤30µV/V). The device draws only 40µA quiescent current and remains stable with output capacitance from 0.1µF to 100µF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.04% (±1.2mV) at +25°C - ensures direct compatibility with 3V-domain precision converters without scaling. |

FAQ
What is the maximum operating temperature range for MAX6033AAUT30#TG16?
MAX6033AAUT30#TG16 is rated for continuous operation from −40°C to +125°C, fully compliant with automotive Grade 0 temperature requirements. This range is guaranteed per the datasheet's operating temperature specification and validated through production testing across the full interval.
Does MAX6033AAUT30#TG16 require an input bypass capacitor?
While not strictly required for stability, MAX6033AAUT30#TG16 recommends a 0.1µF ceramic capacitor between IN and GND to optimize line-transient performance. The device remains functional without it but exhibits improved rejection of supply ripple and step changes when the capacitor is used.
Can MAX6033AAUT30#TG16 drive a 100µF output capacitor?
Yes, MAX6033AAUT30#TG16 is explicitly characterized and guaranteed stable with output capacitance ranging from 0.1µF to 100µF. This wide range allows designers to select optimal capacitance for transient response without risk of oscillation or instability.
What is the purpose of the OUTF and OUTS pins on MAX6033AAUT30#TG16?
OUTF (pin 5) is the force output delivering regulated voltage, while OUTS (pin 6) is the sense input that feeds back to the internal error amplifier. Shorting OUTF to OUTS near the device enables Kelvin sensing, eliminating errors caused by PCB trace resistance between the reference and load.
Is MAX6033AAUT30#TG16 RoHS-compliant?
Yes, MAX6033AAUT30#TG16 is RoHS-compliant per the manufacturer's ordering information, indicated by the "#" suffix. It conforms to EU Directive 2011/65/EU and may contain lead exempted under Annex III of the RoHS directive for specific high-melting-temperature solder applications.
