Frequently Asked Questions
What is the gain range of the INA122P and how is it set?
The INA122P supports a gain range from 1 to 10,000, set by a single external resistor (RG) connected between pins 1 and 8. The gain formula is G = 1 + (200kΩ / RG), making it simple to configure for various signal levels without complex calibration.
What supply voltage does the INA122P support?
The INA122P operates from a single supply of 2.2V to 36V or dual supplies of ±1.1V to ±18V. Its rail-to-rail output capability makes it ideal for low-voltage, single-supply applications such as battery-powered and portable instrumentation systems.
What are typical applications for the INA122P?
Typical applications include bridge transducer amplification (load cells, pressure sensors, strain gauges), medical bio-signal acquisition (ECG, EEG), thermocouple signal conditioning, and industrial data acquisition. Its 83dB CMRR and 250µV offset make it suitable for precision differential measurements.
What package does the INA122P come in and what are alternatives?
The INA122P is available in an 8-pin PDIP (DIP-8) package, which is through-hole and breadboard-friendly. A surface-mount alternative is the INA122U in an 8-pin SOIC package. Other comparable instrumentation amplifiers include the INA128P and INA129P for higher precision requirements.
