The
INA121
is a low power, FET-input instrumentation amplifier.
FET-input IAs reduce errors and noise when amplifying signals from
high impedance sources.
The INA121 offers lower power (450μA), higher accuracy, and lower
cost than previous FET instrumentation amplifiers.
The combination of low cost, low power and low input bias current
make the INA121 an excellent choice for a wide variety of industrial,
test instrumentation and medical applications including ECG and
EEG monitoring systems.
Single Supply, mcroPower,
Instrumentation Amplifier
The
INA122
micropower, single supply instrumentation amplifier is
ideal for battery–powered applications. Operating on a mere 60μA, it
is the lowest power instrumentation amplifier available. Its wide
output voltage swing (150mV to the rails) and wide power supply
range (2.2V to 36V single supply) make it a versatile performer.
Special circuitry allows its input common-mode voltage to extend to
the negative rail (or single supply ground)—a feat that cannot be
duplicated with discrete circuits using single supply op amps.
The INA122 is ideal for a wide range of micropower, single supply
applications in general data acquisition, industrial and medical
instrumentation.
Single Supply, CMOS, Instrumentation Amplifier
The
INA155
is a single supply, CMOS IA with rail-to-rail output and
provides fixed gains of 10 and 50 CMOS inputs provide very high
input impedance low input bias current.
The INA155 operates on supplies from 2.5V to 5.5V and its output
swings to within 10mV of either rail. With 6V/μs slew rate, it can
easily drive CDAC A/D converters.
Its combination of low power, high speed, and low noise make the
INA155 well suited for portable, single supply applications.
