Descripción general

Description

The AD8667ARZ is a precision, low-noise, low-input-offset voltage operational amplifier designed by Analog Devices. It features a rail-to-rail output, ensuring that it can drive loads close to the supply rails, making it suitable for single-supply applications. With a low input offset voltage (typically 50 µV) and low bias current, the AD8667 is ideal for high-accuracy signal conditioning tasks.
Key specifications include a wide voltage supply range (±2.5 V to ±15 V), a gain bandwidth product of 3 MHz, and a low total harmonic distortion (THD) of 0.0005%, making it suitable for audio applications. Its low power consumption (1.2 mA per amplifier) enables use in battery-operated devices.
The AD8667 is housed in an 8-lead SOIC package, facilitating easy integration into various electronic circuits. Its combination of precision, low noise, and rail-to-rail output makes the AD8667ARZ a popular choice for applications in instrumentation, data acquisition, and low-level signal processing.
