AD8519ARZ

AD8519ARZ Description

The AD8519ARZ from Analog Devices Inc. is a high-performance, general-purpose operational amplifier (op-amp) designed for precision analog applications. Packaged in an 8-SOIC tube, this single-channel op-amp operates over a 2.7V to 12V supply range, making it versatile for both low-voltage and moderate-voltage systems. With a gain bandwidth product (GBWP) of 8 MHz and a slew rate of 2.9V/µs, it delivers excellent signal fidelity and transient response. The device features a low input bias current (300 nA) and a moderate input offset voltage (600 µV), ensuring accuracy in signal conditioning and amplification tasks.

AD8519ARZ Features

• Low Power Consumption: Draws only 600µA of supply current, ideal for battery-powered and portable devices.
• High Output Drive: Capable of delivering 25 mA per channel, suitable for driving moderate loads.
• Wide Supply Range: Operates from 2.7V to 12V, accommodating diverse system requirements.
• Stable Performance: MSL 1 (Unlimited) moisture sensitivity ensures reliability in harsh environments.
