Series Voltage Reference General Description 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, …
