TOTAL TI PANEL SOLUTION
In addition to the BUF16820 programmable voltage
reference, TI offers a complete set of ICs for the LCD panel
market, including gamma correction buffers, various
power-supply solutions, and audio power solutions. See
Figure 19 for the total IC solution from TI.
THE BUF16820 IN INDUSTRIAL
APPLICATIONS
The wide supply range, high output current, and very low
cost make the BUF16820 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 more. 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 BUF16820, with its 16
total programmable DAC channels, provides great
flexibility to the entire system by allowing the designer to
change all these parameters via software.
Figure 20 provides various examples of how the
BUF16820 can be used in applications. A microcontroller
with a two-wire serial interface controls the various DACs
of the BUF16820. The BUF16820 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
BUF16820 DACs are set to either the programmed
OTP memory values, or to 0000 if the OTP values
have not been programmed.
