RS3112

Low-Noise, Very Low Drift, Precision Voltage Reference

1 FEATURES

3 DESCRIPTIONS

The RS3112 is a family of low-noise, low-drift, very high

•

Low Temperature Drift: 20 ppm/°C(Max)

precision voltage references. These references are

capable of both sinking and sourcing current, and have

excellent line and load regulation.

High Accuracy: 0.1% Maximum

Low Noise: 35μV_PP/V

Low I_Q: 150μA (Typical)

Operating Temperature Range: -40°C to

+125°C

Excellent temperature drift (20ppm/°C) and high accuracy

(0.1%) are achieved using proprietary design techniques

with 150uA(typical) quiescent current. These features,

combined with low noise, make the RS3112 family ideal

for use in high-precision data acquisition systems.

•

High Output Current: ±10 mA

Micro SIZE PACKAGES: SOIC-8(SOP8)、

SOT23

The RS3112 is available in Green SOIC-8(SOP8) and

SOT23 packages. It operates over an ambient

temperature range of -40°C to +125°C.
