AD8041AR

AD8041AR Description

The AD8041AR from Analog Devices Inc. is a high-performance voltage feedback operational amplifier designed for precision signal conditioning in demanding applications. Housed in an 8-SOIC package, this single-channel IC operates over a 3V to 12V supply range, delivering a 170 MHz bandwidth and an exceptional slew rate of 170V/µs. With a low input bias current of 1.2 µA and a moderate input offset voltage of 2 mV, it ensures accurate signal amplification while consuming just 5.8mA supply current. The device is obsolete but remains relevant for legacy designs requiring high-speed, low-power performance.

AD8041AR Features

• High Bandwidth (170 MHz): Ideal for high-frequency signal processing.
• Fast Slew Rate (170V/µs): Enables rapid signal transitions for pulse and video applications.
• Low Power Consumption (5.8mA): Balances performance with energy efficiency.
• Wide Supply Range (3V to 12V): Supports both single and dual-supply configurations.
• High Output Current (50mA): Drives low-impedance loads effectively.
