MAX6226ALA25+ by Analog Devices

Ultra-High-Precision, Ultra-Low-Noise, Series Voltage Reference


The MAX6226 is an ultra-low-noise, high-precision, low-dropout voltage reference. This family of voltage references feature curvature-correction circuitry and high-stability, laser-trimmed, thin-film resistors that result in 3ppm/°C (max) temperature coefficients and an excellent ±0.02% (max) initial accuracy. The proprietary low-noise reference architecture produces a low flicker noise of 1.45µVP-P and wideband noise as low as 75nV/ (2.5V output) without the increased supply current usually found in low-noise references. Improve wideband noise to 45nV/ and AC power-supply rejection by adding a 0.1µF capacitor at the noise reduction pin. The MAX6226 series mode reference operates from a wide 2.7V to 12.6V supply voltage range and load-regulation specifications are guaranteed to be less than 0.25Ω and 0.05Ω for sink and source currents up to 10mA, respectively. These devices are available over the automotive temperature range of -40°C to +125°C. The MAX6226 typically draws 380µA of supply current and the output voltages are 2.5V, 3.3V, and 5.0V. The MAX6226 also feature dropout voltages as low as 200mV. Unlike conventional shunt-mode (two-terminal) references that waste supply current and require an external resistor, the MAX6226 offers supply current that is virtually independent of supply voltage and does not require an external resistor.The MAX6226 is stable with 0.1µF to 10µF of load capacitance, and is available in an 8-pin ceramic package.
