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/擄C (max) temperature coefficients and
an excellent 鹵0.02% (max) initial accuracy. The propri-
etary low-noise reference architecture produces a low
flicker noise of 1.3碌V
P-P
and wideband noise as low as
60nV/鈭欻z (2.048V output) without the increased supply
current usually found in low-noise references. Improve
wideband noise to 35nV/鈭欻z and AC power-supply
rejection by adding a 0.1碌F 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 0.025鈩?for sink and source cur-
rents up to 10mA. These devices are available over the
automotive temperature range of -40擄C to +125擄C.
The MAX6126 typically draws 380碌A 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 0.1碌F to 10碌F of load
capacitance.
The MAX6126 is available in the tiny 8-pin 碌MAX, as
well as 8-pin SO packages.
