AD8554ARZ is a linear amplifier instrumentation and operational amplifier (OpAmp) designed to add an impedance buffering and gain configured solution in applications that require high common-mode rejection (CMR). It features an open loop gain of 10V/V and a 1.5V to 4.5V wide supply voltage, with a typical supply current of 1mA. A unique feature of the AD8554ARZ is its application as a lowpass filter, which is ideal for use in medical, industrial and consumer applications.

The AD8554ARZ is a monolithic, single-ended input and single-ended output linear amplifier. It is constructed with complimentary P-channel and N-channel MOSFET transistors, the characteristic of which makes it well-suited for AC voltage measurements. The MOSFETs are operated in a differential or balanced configuration to ensure low noise and high accuracy in both AC and DC signals. The amplifier also features integrated temperature compensation, rail-to-rail input/output capability, and low power dissipation.

The AD8554ARZ has a built-in rail-to-rail output voltage range of 1.5V to 4.5V and a gain of 10V/V. Its high common-mode rejection (CMR) of 80dB is at DC and 40kHz, making it suitable for medical, industrial and consumer applications. The amplifier’s wide bandwidth of up to 2MHz is useful for pulse and noise measurements. The device is also adjustable from the outside through external connections, allowing the user to adjust the gain, the signal voltage, the noise level and the linearity.

The AD8554ARZ features low-noise, low-distortion, and low-power dissipation, making it ideal for low-power audio systems. The low-noise and low-distortion characteristics make it ideal for use in recording studios, as it can accurately reproduce acoustic characteristics without any coloration in the output. Furthermore, the device can be used in digital signal processing, ensuring a clean and precise waveform. Along with its high common-mode rejection, the AD8554ARZ can also be used in power supply and data acquisition applications, such as instrumentation and control systems, among others.

The AD8554ARZ is supplied in an SO-8 package, and is available in an industrial temperature range of −40°C to +125°C. It is lead-free and RoHS compliant. It comes with a 2-year warranty. This device is optimized for accuracy, space, power consumption and performance in various applications.
