APPLICATIONS
This voltage reference can be used in high precision
industrial applications, data acquisition systems, high
resolution ADCs or DACs, optical control circuits, medical
instruments, etc.
DESCRIPTION
The 3-terminal voltage reference features high accuracy,
ultra low noise, and low temperature drift, which is a best
choice for optical applications and high end data acquisition
systems, etc. The output voltage change is ±1μV when the
input voltage, temperature or the output current changes.
Figure 1 shows the photos of voltage reference.
It comes with a curvature-correction circuit and lasertrimmed
thin-film resistors so that a low temperature
coefficient of 1ppm/°C can be achieved. This voltage
reference draws as low as 90μA of supply current and can
source 10mA or sink −5mA of load current. It provides a
supply current that is virtually independent of the supply
voltage and do not need an external resistor, which is better
than those conventional two-terminal references that need an
external resistor. Moreover, this voltage reference is
internally compensated so that no external compensation
capacitor is needed. This helps save valuable board space for
most applications. Its low dropout voltage and low supply
current make these devices ideal for battery-powered and
low voltage systems.
Figure 1 is the photos of this voltage reference. Figure 2 is
the real size top view of the voltage reference showing the
pin names and locations with the actual size. The pin
functions are shown in Table 1.
