The MAX6126AASA25+ is an ultra-low-noise, high-precision, low-dropout Voltage Reference for high-resolution A/D and D/A converters. This family of voltage references feature curvature-correction circuitry and high-stability, laser-trimmed, thin-film resistors that result in 3ppm/°C (maximum) temperature coefficients and an excellent ±0.02% (maximum) 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 2.7 to 12.6V supply voltage range and load-regulation specifications are guaranteed to be less than 0.025R for sink and source currents up to 10mA.
