Application Information

Size

ECV321 series op amps are unity-gain stable and suitable for a wide range of general-purpose applications. The

small footprints of the ECV321 series packages save space on printed circuit boards and enable the design of

smaller electronic products.

Power Supply Bypassing and Board Layout

ECV321 series operates from a single 1.8V to 5.5V supply or dual ±0.9V to ±2.75V supplies. For best performance, a

Low Supply Current

The low supply current (typical 55µA) of ECV321 series will help to maximize battery life. They are ideal for battery

powered Systems
