It can be used as a buffer amplifier for ADC/DACs, voltage and current measurement, as a voltage buffer for high-impedance transducers, and as an instrumentation amplifier for medical, industrial and communications applications.

Because of its high power-output-per-unit area ratio, the AD8351ACPZ-R7 can also be used in power amplifiers applications, such as RF or industrial audio. Additionally, it is well-suited for power amplifiers, instrumentation amplifiers and buffer amplifiers in automotive, audio, industrial and communications applications.

Working Principle

The fundamentals of the AD8351ACPZ-R7 working principle are fairly straightforward. It is an integrated amplifier output stage with high input impedance, low output impedance, wide dynamic voltage range, and low distortion. The circuit has two differential inputs, one of which is the output resistor feedback, while the other one is the input signal. The output voltage is proportional to the difference between the two inputs.

The AD8351ACPZ-R7 also benefits from the use of high-speed, parallel, and current-feedback amplifier stages. These stages can provide a low output impedance, improved linearity, and better noise immunity. Furthermore, the amplifier also has stringent performance requirements, such as temperature-compensated gain, temperature-stabilized differential amplifier, and improved EMI/RFI performance.

Finally, the amplifier includes a power-saving energy recovery circuit. This circuit reduces the power consumption and increases the efficiency of the entire system. It works by recovering the energy of the amplifier’s input and output signals, and then recycling it back into the system.
