INA125 Instrumentation Amplifier with Precision Voltage Reference IC DIP-16
The INA125 is a low power, high accuracy instrumentation amplifier with a precision voltage reference. It provides complete bridge excitation and precision differential-input amplification on a single integrated circuit. A single external resistor sets any gain from 4 to 10,000. The INA125 is laser-trimmed for low offset voltage (250?V), low offset drift (2?V/?C), and high common-mode rejection (100dB at G = 100). It operates on single ( 2.7V to 36V) or dual (?1.35V to ?18V) supplies. The voltage reference is externally adjustable with pinselectable voltages of 2.5V, 5V, or 10V, allowing use with a variety of transducers.
INA126 Micro Power Instrumentation Amplifier IC DIP-8
The INA126 is precision instrumentation amplifiers for accurate, low noise differential-signal acquisition. Their two-op-amp design provides excellent performance with low quiescent current (175 ?A/channel). Combined with a wide operating voltage range of ?1.35 V to ?18 V, makes the INA126 ideal for portable instrumentation and data acquisition systems.
Gain can be set from 5 V/V to 10000 V/V with a single external resistor. Laser-trimmed input circuitry provides low offset voltage (250-?V maximum), low offset voltage drift (3-?V/?C maximum), and excellent common-mode rejection.
INA128 Low Power Instrumentation Amplifier IC DIP-8
The INA128 is low-power, general purpose instrumentation amplifiers offering excellent accuracy. The versatile 3-op amp design and small size make these amplifiers ideal for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain (200 kHz at G = 100).
A single external resistor sets any gain from 1 to 10,000. The INA128 provides an industry-standard gain equation. The INA128 is available in 8-pin plastic DIP and SO-8 surface-mount packages, specified for the ?40?C to 85?C temperature range. The INA128 is also available in a dual configuration, the INA2128.
INA132U
The INA132 is a low power, unity-gain differential
amplifier consisting of a precision op amp with a
precision resistor network. The on-chip resistors are
laser trimmed for accurate gain and high commonmode rejection. Excellent TCR tracking of the resistors maintains gain accuracy and common-mode rejection over temperature. The internal op amp?s common-mode range extends to the negative supply?
ideal for single-supply applications. It operates on
single (2.7V to 36V) or dual supplies (?1.35V to
?18V).
INA137UA
The INA137 and INA2137 are differential line receivers
consisting of high performance op amps with on-chip
precision resistors. They are fully specified for high
performance audio applications and have excellent ac
specifications, including low distortion (0.0005% at
1kHz) and high slew rate (14V/?s), assuring good
dynamic response. In addition, wide output voltage
swing and high output drive capability allow use in a
wide variety of demanding applications. The dual version features completely independent circuitry for lowest crosstalk and freedom from interaction, even when
overdriven or overloaded.
INA139NA/250
The device converts a differential input voltage to a
current output. This current is converted back to a
voltage with an external load resistor that sets any
gain from 1 to over 100. Although designed for
current shunt measurement, the circuit invites
creative applications in measurement and level
shifting.
Both the INA139 and INA169 are available in 5-pin
SOT-23 packages. The INA139 device is specified for
the ?40?C to 125?C temperature range, and the
INA169 is specified from ?40?C to 85?C.
INA155UA-ND
The INA155 is a low-cost CMOS instrumentation
amplifier with rail-to-rail output swing optimized for
low voltage, single-supply operation.
Wide bandwidth (550kHz in G = 10) and high slew
rate (6.5V/?s) make the INA155 suitable for driving
sampling A/D converters as well as general purpose
and audio applications. Fast settling time allows use
with higher speed sensors and transducers and rapid
scanning data acquisition systems.
INA163UA
The INA163 is a very low-noise, low-distortion, monolithic instrumentation amplifier. Its current-feedback
circuitry achieves very wide bandwidth and excellent
dynamic response over a wide range of gain. It is ideal
for low-level audio signals such as balanced lowimpedance microphones. Many industrial, instrumentation, and medical applications also benefit from its
low noise and wide bandwidth.
Unique distortion cancellation circuitry reduces distortion to extremely low levels, even in high gain. The
INA163 provides near-theoretical noise performance
for 200? source impedance. Its differential input, low
noise, and low distortion provide superior performance
in professional microphone amplifier applications
