Application Information
EC5721 series op amps are unity -gain stable and suitable for a wide range of general -purpose applications. The small footprints of the EC5721 series packages save space on printed circuit boards and enable the design of smaller electronic products. Power Supply Bypassing and Board Layout 0.1μF ceramic capacitor should be placed close to the V DD 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 160μA) of EC5721 series will help to maximize battery life. They are ideal for battery powered Systems Operating Voltage EC5721 series operate under wide input supply voltage (2.2V to 5.5V). In addition, all tem perature specifications apply from -40℃ to + 125℃. Most behavior remains unchanged throughout the full operating voltage range. These guarantees ensure operation throughout the single Li-Ion battery lifetime. EC5721NN XX X B2：SOT23-5L M1：SOP-8L
