INA126PAG4 Application Field and Working Principle

Introduction

The INA126PAG4 is a low-noise, high-accuracy, single-ended, High Common-Mode Voltage, Rail-to-Rail Input-Output instrumentation amplifier featuring low offset voltage, low input bias current, and high slew rate. This device is designed for instrumentation and general purpose signal conditioning application requiring high accuracy.

Linear-Amplifiers-Instrumentation

The INA126PAG4 belongs to the linear-amplifiers-instrumentation family of amplifiers. This device can be used to amplify the differential voltage between two input signal sources. The common-mode voltage range of the INA126PAG4 is between ground potential and rail-to-rail, making this device ideal for power supplies and signal conditioning applications with high common-mode voltages. Additionally, the input bias current is extremely low (-1 pA typ.), and the offset voltage is very low at 0.4 mV max.

Operational-Amplifiers

The INA126PAG4 incorporates a standard voltage feedback configuration, allowing it to function as an Op-Amp, Buffer Amp, or instrumentation amplifier. The high input impedance of the INA126PAG4, along with its low noise (7 nV/√Hz @ 10 kHz adding to the RMS noise from the source) makes it suitable for high-precision signal acquisition systems.

Buffer-Amplifier

The INA126PAG4 buffer amplifier configuration provides a high input impedance ideal for signal acquisition systems and other applications requiring low noise and power consumption. This device features a maximum output current capability of 25 mA, which allows the INA126PAG4 to drive a wide range of analog signals, such as single-ended/differential signals, filter circuits, sigma-delta converters or analog to digital converters.

Conclusion

The INA126PAG4 is a versatile and low-noise, single-ended, High Common-Mode Voltage, Rail-to-Rail Input-Output instrumentation amplifier featuring low offset voltage, low input bias current, and high slew rate. This amplifier is suitable for a variety of signal conditioning and data acquisition applications. Its low noise and high common-mode voltage range make the INA126PAG4 ideal for power supplies and signal conditioning applications, and its low input bias current, low offset voltage, and high slew rate make it highly suitable for high-precision signal acquisition systems.
