Ultra-High-Precision, Ultra-Low-Noise,
Series Voltage Reference
General Description
The MAX6126 is an ultra-low-noise, high-precision, low-
dropout voltage reference. This family of voltage refer-
ences 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 propri-
etary low-noise reference architecture produces a low
flicker noise of 1.3µV
P-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 guaran-
teed to be less than 0.025Ω for sink and source cur-
rents 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, 3.000V, 4.096V, and
5.000V output voltages. These devices 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 resis-
tor. The MAX6126 is stable with 0.1µF to 10µF of load
capacitance.
The MAX6126 is available in the tiny 8-pin µMAX, as
well as 8-pin SO packages.
