DATA ACQUISITION AND MONITORING APPLICATIONS
Product Applications
ANALOG FUNCTIONS
—complex and non-
linear signal processing includes active filters,
log amps, analog multipliers, etc. See page 96.
MULTIPLEXER
—signal selector (several in-
puts, one output). Signal selection is by logic
levels. See page 95.
ANALOG/DIGITAL CONVERTERS
—a com
plete line of converters that provide flexibility
(various input ranges, serial/parallel interface,
multiple channels, sampling rates, etc.), and a
complete solution (V
REF
, sample-and-hold, in-
ternal clock all on one chip), along wth 12-
and 16-bit pin-for-pin compatibility in selected
models. See page 59.
DIGITAL/ANALOG CONVERTERS
—these
products provide up to 20 bits of resolution,
current or voltage output, serial or parallel
interface, and up to four DACs on a chip, along
wth other key features for Industrial and Pro-
cess Control applications. See page 77.
DATA ACQUISITION SYSTEM
—complete
A/D solution (multiplexer, PGA, reference, delta-
sigma modulator/filter) all in one package wth
24 bits of resolution on selected models. See
page 60.
REFERENCE AND REGULATORS
—pro-
vides controlled voltages and currents. See page
91 (reference), page 48 (regulators).
OUTPUT DEVICES
—unique output capabili-
ties.
Power Amplifiers—high-voltage and high-
current op amps. See page 14.
Buffer Amplifiers—high-speed drivers. See
page 13.
Swtchers—PWM Drivers. See page 47.

ISOLATION
—provides galvanic isolation in
signal path.
Amplifier—transmts analog signals across
a galvanically isolated barrier. See page 53.
DC/DC Converter—provides isolated power
for input stage. See page 54.
AMPLIFIERS
—typical sensor interface cir-
cuit elements.
Operational Amplifier—basic building block
for signal processing. Circuit transfer func-
tion set by user-selected components. See
page 5.
Instrumentation Amplifier—gain up to 10000
set by pin strapping or fixed resistor. Very
high common-mode rejection. See page 33.
Difference Amplifier—fixed gain of 1/2 to 10
set by pin strapping. High common-mode
rejection. See page 34.
Programmable Gain Amplifier—digitally pro-
grammed gain version of instrumentation
amp. See page 39.
