Application Information

Size

EC5821 series op amps are unity-gain stable and suitable for a wide range of general-purpose applications.

The small footprints of the EC5821 series packages save space on printed circuit boards and enable the

design of smaller electronic

products.

Power Supply Bypassing and Board Layout

EC5821 series operates from a single 2.2V to 5.5V supply or dual ±1.1V to ±2.75V supplies. For best

performance, a 0.1µF ceramic capacitor should be placed close to the VDD pin in single supply operation. For

dual supply operation, both VDD and VSS supplies should be bypassed to ground with separate 0.1µFceramic

capacitors.

Low Supply Current

The low supply current (typical 400µA) of EC5821 series will help to maximize battery life. They are ideal for

battery powered Systems

Operating Voltage

EC5821 series operate under wide input supply voltage (2.2V to 5.5V). In addition, all temperature

specifications apply from

voltage range. These guarantees ensure operation throughout the single Li-Ion battery lifetime.
