Specialized ICs

The AD8190ACPZ-R7 is a dual-channel, low-power, low-noise operational amplifier optimized for medical applications. It has high common-mode rejection, a low-distortion signal path, and a low offset voltage in the input stage that, combined, make it well suited for capturing small signals from sensors.

The device has a wide range of applications in the medical field, such as in ECG, EEG, pulse oximetry, stress tests, ultrasound, and non-invasive blood pressure monitoring systems. It is also useful for signal conditioning in pressure transducers, level detection, and signal reception in test and measurement instruments. It offers superior performance over standard operational amplifiers by providing low power consumption, high immunity to EMI, and greater signal-to-noise ratio.

Key Features

Working Principle

The AD8190ACPZ-R7 is a cascade-structure, low-power, low-noise operational amplifier. Its input stage consists of a differential pair of MOSFETs, which is followed by a cascode buffer. The cascode buffer consists of two MOSFETs in series - one in the common-gate configuration, and one in the source-follower configuration. This structure provides a rail-to-rail input range, low-distortion signal path, and high common-mode rejection.

The device also includes a low-noise input stage consisting of a differential pair of JFETs. This stage provides high input impedance and low input offset voltage, thus enabling it to capture small signals from sensors without introducing distortion. The output stage consists of a single MOSFET in a source-follower configuration. This stage provides a low-power and low-noise output signal with rail-to-rail dynamic range.

Applications

The wide range of features offered by the AD8190ACPZ-R7 have enabled it to find many applications in the medical field. Its low power consumption and EMI immunity make it a good choice for use in medical monitoring and diagnostic equipment, such as ECG, EEG, pulse oximetry, stress tests, and non-invasive blood pressure monitors. It can also be used in pressure transducers, level detection, and signal reception in test and measurement instruments.
