MAX6226
Ultra-High-Precision, Ultra-Low-Noise, Series Voltage Reference
General Description
The MAX6226 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 5ppm/°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/√Hz (2.5V output) without the increased supply current usually found in low-noise references. Improve wideband noise to 45nV/√Hz and AC power-supply rejection by adding a 0.
