AD8062AR

AD8062AR Description

The AD8062AR from Analog Devices Inc. is a high-performance, dual-channel voltage feedback operational amplifier designed for precision signal conditioning in demanding applications. Operating over a 2.7V to 8V supply range, it delivers 320 MHz bandwidth and an exceptional slew rate of 650V/µs, making it ideal for high-speed analog systems. With low input bias current (3.5 µA) and minimal input offset voltage (1 mV), it ensures accuracy in sensitive circuits. Packaged in an 8-pin SOIC tube, this surface-mount IC is optimized for space-constrained designs but is now marked obsolete, so alternative sourcing may be required.

AD8062AR Features

• High-Speed Performance: 320 MHz bandwidth and 650V/µs slew rate enable rapid signal processing.
• Low Power Consumption: Dual-channel operation at 6.8mA per channel balances efficiency with performance.
• Wide Supply Range: Supports 2.7V to 8V, suitable for battery-powered and low-voltage systems.
• Robust Output Drive: 50 mA output current per channel for driving capacitive loads or transmission lines.
• Low Noise: Minimal input offset voltage and bias current enhance precision in sensor interfaces and data acquisition.
• Surface-Mount Design: 8SOIC package (MSL-1 rated) ensures compatibility with automated assembly.

AD8062AR Applications

• High-Speed Signal Processing: Ideal for video amplification, ADC drivers, and RF front-ends.
• Portable Electronics: Low-voltage operation suits handheld devices and battery-powered instrumentation.
