INA101/INA102 High-Performance, Low-Power Instrumentation Amplifier
●The INA101/2 is a low cost, high accuracy instrumentation amplifier that requires only one external resistor to set gains of 1 to 10,000. Furthermore, the INA101/2 features 8-lead SOIC packaging that is smaller than discrete designs and offers lower power (only 1.56mA supply current), making it a good fit for battery-powered, portable (or remote) applications.
●The INA101/2, with its high accuracy of 0.8ppm maximum nonlinearity, low offset voltage of 12μV max, is ideal for use in precision data acquisition systems, such as weigh scales and transducer interfaces. Furthermore, the low noise, low input bias current, and low power of the INA101/2 make it well suited for medical applications, such as ECG and noninvasive blood pressure monitors.
●The INA101/2 works well as a preamplifier due to its low input voltage noise of 14nV/√Hz at 1kHz, 3μVPP in the 0.1Hz to 10Hz band, and 0.35pA/√Hz input current noise. Also, the INA101/2 is well suited for multiplexed applications with its settling time of 75μs to 0.01%, and its cost is low enough to enable designs with one in-amp per channel.
