Application Information

Size

EC5741 series op amps are unity-gain stable and suitable for a wide range of general-purpose applications.

The small footprints of the EC5741 series packages save space on printed circuit boards and enable the

design of smaller electronic products.

Power Supply Bypassing and Board Layout

EC5741 series operates from a single 1.4V to 5.5V supply or dual ±0.7V to ±2.75V supplies. For best

performance, a 0.1μF ceramic capacitor should be placed close to the V

capacitors.

Low Supply Current

The low supply current (1.4

μA) of EC5741 series will help to maximize battery life. They are ideal for battery

powered Systems
