Product Introduction
The MAX6126 is an ultra- low- noise, high- precision, lowdropout 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 1.3μVₚ₋ₚ and wideband noise as low as 60nV / √Hz (2.048V output) without the increased supply current usually found in low- noise references. Improve wideband noise to 35nV / √Hz and AC power- supply rejection by adding a 0.1μF capacitor at the noise reduction pin. The MAX6126 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 0.025Ω for sink and source currents up to 10mA. These devices are available over the automotive temperature range of - 40°C to +125°C.
The MAX6126 typically draws 380μA of supply current and is available in 2.048V, 2.500V, 2.800V, 3.000V, 3.300V, 3.600V, 4.096V, and 5.000V output voltages. The MAX6126 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 MAX6126 offers supply current that is virtually independent of supply voltage and does not require an external resistor. The MAX6126 is stable with 0.1μF to 10μF of load capacitance.
The MAX6126 is available in the tiny 8- pin μMAX⁽ᴮ⁾, as well as 8- pin SO packages.
