The AD8652ARMZ is a precision, low-noise, low-distortion instrumentation amplifier with a high common-mode rejection ratio. It is designed to provide an effective and reliable solution for driving high-impedance transducers and platinum RTDs, making it well-suited for use in demanding applications such as medical and analytical instrumentation. The AD8652ARMZ also excels in audio signal processing, offering low-noise amplification and high linearity.

The AD8652ARMZ features a two stage instrumentation amplifier with an input stage featuring low-noise NFETs and a low distortion VCA-based gain control circuit. The input stage provides high accuracy and low distortion, while the VCA-based gain control circuit minimizes circuit settling time, rejection of unwanted signals, and interaction with interfering signals.

The AD8652ARMZ has a maximum common-mode rejection ratio of 100 dB, and features an adjustable gain range of two-to-ten, meaning it can be used to amplify signals with magnitudes ranging from microvolt to millivolt. The low-noise design also allows it to amplify tiny signal levels without adding noise from the amplifier. The AD8652ARMZ can be effectively used to measure small signals in the presence of large signal disturbances.

The AD8652ARMZ can be powered from a single, dual, or triple supply voltage, ranging from 2.7V to 5.5V. It also features a rail-to-rail input and output range, and very low DC offset. A high slew rate of 3.3V/us, low input noise of 2.8 nV/√Hz, and large bandwidth of 10 MHz make the AD8652ARMZ a perfect choice for precision instrumentation amplifiers.

The AD8652ARMZ features a slew-rate protection transient limiter to protect against large and sudden output current, and it can also be enabled to filter out unwanted signals in high-noise environments. The AD8652ARMZ includes a short- and open-circuit-protected supply that enables it be connected to DC currents that exceed its rated power input. It also includes a thermal shutdown protection and a power supply current monitoring feature that enables it to be used in mission-critical applications.

The AD8652ARMZ is a remarkably versatile and robust instrumentation amplifier, offering a variety of features and benefits depending on the application. Its high common-mode rejection ratio and low distortion, low-noise design make it an ideal choice for precision instrumentation, medical, and analytical instrumentation. Its adjustable gain range and wide voltage range make it suitable for low-level signal processing, while its high slew rate and robust protection features enable it to be used in mission-critical applications.
