Ultra-High-Precision, Ultra-Low-Noise,

Series Voltage Reference

General Description

Features

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 ±±.±2ꢀ (max) initial accuracy. The propri-

etary low-noise reference architecture produces a low

6±nV/√Hz (2.±48V 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 ±.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 ±.±25Ω for sink and source cur-

rents up to 1±mA. These devices are available over the

automotive temperature range of -4±°C to +125°C.

The MAX6126 typically draws 38±µA of supply current

and is available in 2.±48V, 2.5±±V, 3.±±±V, 4.±96V, and

5.±±±V output voltages. These devices also feature

dropout voltages as low as 2±±mV. 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 ±.1µF to 1±µF of load

capacitance.
