The AD8676ARZ is an ideal solution for any instrumentation amplifier application, specifically designed to achieve excellent performance in a low power, small form factor. This device is a 10×-Low Power, Unipolar, Low Noise, High CMRR (common mode rejection ratio), Low Offset Voltage Instrumentation Amplifier, with rail-to-rail inputs and outputs. Housed in a tiny SOT-23 package (MSOP is also available), the AD8676ARZ provides a cost-effective solution for demanding instrumentation amplifier designs.

The basic working principle of the AD8676ARZ is simple. The device has two ESD protected input pins, two differential output pins and two power supply pins. A differential signal is applied to the input pins, and the output is then amplified, buffered and stabilized. Due to its exceptionally low noise and wide power supply range, it is an ideal choice for a wide range of instrumentation applications, including test and measure equipment, medical instruments, automotive diagnostic systems, power supply monitoring and control, vibration monitors and more.

The AD8676ARZ is specified for a wide range of power supply voltages, ranging from 2.5V to 16V. The device is designed to provide exceptional performance, with low noise (3.7nV/√Hz), high CMRR (150dB), and low offset voltage (10µV). The device also features very low quiescent current, making it an ideal choice for portable battery powered applications. Due to its low power consumption and small package, the AD8676ARZ is ideal for space-constrained instrumentation designs.

The AD8676ARZ offers excellent linearity performance and wide dynamic range. It has a linearity of ± 0.02 % with a wide signal range of ±11 mV to ±3V, making it suitable for a wide range of signal conditioning applications. The device also boasts high bandwidth performance, with a -3 dB bandwidth of 40 MHz. Furthermore, the AD8676ARZ contains a low-offset voltage buffer, making it ideal for precision, high-gain instrumentation applications.

In summary, the AD8676ARZ is an excellent solution for instrumentation amplifier applications due to its wide power supply range, low noise, low quiescent current and rail-to-rail inputs and outputs. Its small package, combined with its high CMRR and excellent linearity, make it an ideal choice for demanding instrumentation designs.
