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 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/√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 0.1μF 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 …
