INA12x Precision, Low Power Instrumentation Amplifiers
1 Features 3 Description
The INA128 and INA129 are low-power, general
1
• Low Offset Voltage: 50 μV Maximum
purpose instrumentation amplifiers offering excellent
• Low Drift: 0.5 μV/°C Maximum
accuracy. The versatile 3-op amp design and small
• Low Input Bias Current: 5 nA Maximum
size make these amplifiers ideal for a wide range of
applications. Current-feedback input circuitry provides
• High CMR: 120 dB minimum
wide bandwidth even at high gain (200 kHz at G =
• Inputs Protected to ±40 V
100).
• Wide Supply Range: ±2.25 V to ±18 V
A single external resistor sets any gain from 1 to
• Low Quiescent Current: 700 μA
10,000. The INA128 provides an industry-standard
• 8-PIN Plastic Dip, SO-8
gain equation; the INA129 gain equation is
compatible with the AD620.
2 Applications
The INA12x is laser-trimmed for very low offset
• Bridge Amplifier
voltage (50 μV), drift (0.5 μV/°C) and high common-
mode rejection (120 dB at G ≥ 100). The INA12x
• Thermocouple Amplifier
operates with power supplies as low as ±2.25 V, and
• RTD Sensor Amplifier
quiescent current is only 700 μA, ideal for battery-
• Medical Instrumentation
operated systems. Internal input protection can
withstand up to ±40 V without damage.
• Data Acquisition
The INA12x 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.
