AD8207WBRZ-RL

The AD8207WBRZ-RL is an ultra-low distortion instrumentation amplifier designed for audio signal processing applications. It is a powerful and low cost solution for a variety of applications ranging from differential signal conditioning to voltage buffering.

The AD8207WBRZ-RL is a high-performance precision instrumentation amplifier designed for high end audio applications, such as hi-fi pre-amplifiers and audio/video processors. Featuring ultra-low distortion and wide signal bandwidth, the amplifier is engineered to provide superior linearity and signal integrity in applications that require accurate signal measurement and amplification.

Working principle:

The AD8207WBRZ-RL operates by applying a differential voltage between two input signals and then amplifying the difference to the power supply voltage level. The output signal is proportional to the difference between the two input signals. The amplifier has both a differential and a common mode gain, allowing it to accommodate low input signal levels while rejecting common mode noise, and provides optimal amplification while keeping noise and distortion to a minimum.

The AD8207WBRZ-RL contains three gain stages. The first stage is an inverting amplifier, which amplifies the difference between the inputs. The second stage has a high gain that amplifies the difference signal and adds a low-level signal conditioner to reject common-mode noise. The third stage, a non-inverting amplifier, provides the desired voltage level for the output signal.

The AD8207WBRZ-RL is configured with a power supply range from 4.2–15V and has an input voltage range of up to ±22 V. Additionally, the device features ultra-low distortion (0.001% THD+N) and wide signal bandwidth (2 MHz).

Application field:

The AD8207WBRZ-RL is an ideal solution for a variety of audio signal processing applications including headphone amplifiers, pre-amplifiers, power amplifiers, active speakers, equalizers, and bass enhancement systems. Additionally, the device is suitable for applications such as instrumentation amplifiers, voltage buffers, and differential signal conditioners.

The device’s low distortion, wide signal bandwidth, high input voltage range, and low power requirements make it well-suited for a variety of applications. Its precision performance is also ideal for analog-to-digital converters, digital audio signal processors, and other audio signal processing systems.

In conclusion, the AD8207WBRZ-RL is an excellent choice for high-fidelity audio signal processing and instrumentation. Its ultra-low distortion and wide signal bandwidth make it an ideal solution for a variety of applications ranging from pre-amplifiers to differential signal conditioners.
