BUF12800 IN INDUSTRIAL APPLICATIONS
The wide supply range, high output current and very low
cost make the BUF12800 attractive for a range of medium
accuracy industrial applications such as programmable
power supplies, multi-channel data-acquisition systems,
data-loggers,
sensor
excitation
power-supply generation, and others. Each DAC channel
features 1LSB DNL and INL.
and
linearization,
Many systems require different levels of biasing and power
supply for various components as well as sensor
excitation, control-loop set-points, voltage outputs, current
outputs, and other functions. The BUF12800, with its 12
programmable DAC channels, provides great flexibility to
the whole system by allowing the designer to change all
these parameters via software.
Figure 16 provides ideas on how the BUF12800 can be
used in an application. A micro controller with two-wire
serial interface controls the various DACs of the
BUF12800. The BUF12800 can be used for:
sensor excitation
programmable bias/reference voltages
variable power-supplies
high-current voltage output
4-20mA output
set-point generators for control loops.
NOTE:
At power-up the output voltages of the BUF12800
DACs are pre-defined by the codes in Table 1. Therefore,
each DAC voltage will be set to a different level at
power-up or reset.
