AD8574ARZ

AD8574ARZ Description

The AD8574ARZ from Analog Devices Inc. is a high-performance, zero-drift operational amplifier designed for precision applications requiring minimal input offset voltage and drift. Housed in a 14-SOIC package, this quad-channel op-amp operates over a 2.7V to 5V supply range, making it suitable for low-voltage systems. With an ultra-low input offset voltage of 1 µV and input bias current of 1 nA, it ensures exceptional accuracy in signal conditioning and sensor interfacing. The device features a 1.5 MHz gain bandwidth product (GBW) and a slew rate of 0.4V/µs, balancing speed and precision for DC and low-frequency applications. Its zero-drift architecture eliminates the need for periodic calibration, reducing system complexity and maintenance.

AD8574ARZ Features

• Ultra-low offset voltage (1 µV) and drift for precision applications.
• Quad-channel design (4 circuits) with 30 mA output current per channel.
• Wide supply range (2.7V–5V) and low supply current (850 µA per channel) for power-sensitive designs.
• 1.5 MHz GBW and 0.4V/µs slew rate for stable performance in low-frequency signal chains.
• ROHS3 Compliant and REACH unaffected, meeting environmental regulations.
