AD8667ARZ Features

The AD8667ARZ has a variety of features that make it an ideal solution for device designers looking for an amplifier with a high level of accuracy, precision and low-distortion parameters. It includes a low-noise input stage with a single-ended input impedance characteristic that allows it to be used as either a differential input or single-ended input amplifier. The AD8667ARZ also has a wide dynamic range of -3V to +3V with a low power consumption of 28mW/channel. The output stage consists of a low-noise, low-distortion class A/B output stage that provides both low-noise and high-power levels. It also features a fast response time, low input bias current and a wide gain bandwidth of 0.5 MHz for excellent signal transmission.The AD8667ARZ is fully DAB (Dynamic Audio Balance) compatible and provides an on-chip 2nd order, 4 pole filter with a pass-band from 0 Hz to a maximum of 260kHz. Additionally, the AD8667ARZ features a very low capacitive loading, a low input bias current and a wide gain bandwidth. The chip also includes an adjustable digital gain/level adjustment and a trim pin for fine digital and analog control.

AD8667ARZ Application Field and Working Principle

The AD8667ARZ can be used in a wide range of applications that require precise signal measurements. These include precision measurement of line receivers, analog-to-digital converters, and digital signal processing systems. Additionally, it can be used in biomedical applications, audio preamps, and radio communications systems.The AD8667ARZ works by amplifying the input signal with very low noise and distortion parameters. It does this by using a differential input stage and a class A/B output stage. The output stage is designed to minimize parasitic capacitance and is designed to provide a low-impedance output with low distortion. Additionally, the wide gain bandwidth of 0.5 MHz ensures excellent signal transmission and accurate amplifications.To provide the highest level of performance, the AD8667ARZ data acquisition system is designed to be used in combination with the AD8667ARZ Digital Byte Register, which allows for the precise setting of gain, multiplexer settings and digital filtering. This combination allows the device to provide precise and accurate measurements with minimal noise and distortion.
