The  AD8132AR-REEL7  is an instrumentation amplifier (IA)  from a family of instrumentation amplifiers offered by Analog Devices, Inc. The AD8132AR-REEL7 is widely used in applications such as temperature measurements, thermocouple sensing, automotive, medical and industrial control systems, audio systems, and industrial automation.

The main features of the AD8132AR-REEL7 are its low noise performance, low power consumption, and low gain sensitivity. The chip operates from a single power supply and is available with wide range of gain and offset performance. It has good common mode rejection ratio (CMRR) of 70dB when operating from a 10V supply.

The AD8132AR-REEL7 is a low power, low noise IA with a gain of 100V/V. It is composed of a high precision, abrasion resistant, leakage current compensated CMOS process. The two individual amplifier stages (with an optional feedback) and a single differential output stage form the IA.

The INA has a wide input bandwidth of 10kHz, an offset voltage value of 2500 µV, a CMRR of 80dB, and a unity gain bandwidth of 2MHz. It also has a wide temperature range of -40°C – +140°C, making it suitable for use in industrial automation and process control systems.

The AD8132AR-REEL7 can be configured as a three-op amp IA configuration, a four-op amp IA configuration, and a two-op amp IA configuration. In addition, the IA can be used in a number of applications such as load cell measurement, force measurement, level measurement, and differential pressure sensing.

The operation of the AD8132AR-REEL7 involves two stages. The first stage amplifies the input signal while the second amplifies the error signal. The first stage has two op amps (A1 and A2) in a differential configuration and the second stage has a single op amp (A3) in a non-inverting configuration. The two stages are connected in series and the amplified signal is fed to the differential output stage. The output signal has low offset voltage and high CMRR.

The AD8132AR-REEL7 is a low-power, low-noise, IA suitable for a wide range of gain and offset control application needs. It is easy to use, provides high CMRR, and has wide input bandwidth. Its wide temperature range and low power consumption make it suitable for use in a variety of applications, from temperature sensing to industrial automation.
