Product Description

The AD8042AR is a high-speed, low-power voltage feedback op-amp that supports +3 V, +5 V, or ±5 V supply configurations. It allows true single-supply operation with input capability extending 200 mV below the negative rail and up to 1 V below the positive rail. Output range reaches to within 30 mV of both supply rails, maximizing dynamic range. These attributes make it well-suited for demanding video gear and portable, high-performance devices.
