Sensors Active Filters Cellular and Cordless Phones Laptops and PDAs Audio Handheld Test Equipment Battery-Powered Instrumentation A/D Converters GENERAL DESCRIPTION The CBM863X have a high gain-bandwidth product of 6MHz, a slew rate of 4.2V/μs, and a quiescent current of 470μA per amplifier at 5V. The CBM863X are designed to provide optimal performance in low voltage and low noise systems. They provide rail-to-rail output swing into heavy loads. The input common mode voltage range includes ground, and the maximum input offset voltage is 3.5mV for CBM863X. They are specified over the extended industrial temperature range (-40℃ to +125℃). The operating range is from 2.1V to 5.5V. The CBM8631 single is available in Green SC70-5, SOT23-5 and SOP-8 packages. The CBM8632 dual is available in Green SOP-8 and MSOP-8 packages. The CBM8634 Quad is available in Green SOP-14 and TSSOP-14 packages. A ll data sheet.com

www.corebai.com CBM8631-CBM8632-CBM8634 OPERATION INSTRUCTION Application Note Size CBM863X series op amps are unity-gain stable and suitable for a wide range of general-purpose applications. The small footprints of the CBM863X series packages save space on printed circuit boards and enable the design of smaller electronic products. Power Supply Bypassing and Board Layout CBM863X series operates from a single 2.1V to 5.5V supply or dual ±1.05V to ±2.75V supplies. For best performance, a 0.1μF ceramic capacitor should be placed close to the V DD pin in single supply operation. For dual supply operation, both V DD and V SS supplies should be bypassed to ground with separate 0.1μF ceramic capacitors. Low Supply Current The low supply current (typical 470uA per channel) of CBM863X series will help to maximize battery life. They are ideal for battery powered systems Operating Voltage CBM863X series operate under wide input supply voltage (2.1V to 5.5V). In addition, all temperature 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 Rail-to-Rail Input The input common-mode range of CBM863X series extends 100mV beyond the supply rails (VSS-0.1V to V DD+0.1V). This is achieved by using complementary input stage. For normal operation, inputs should be limited to this range. Rail-to-Rail Output Rail-to-Rail output swing provides maximum possible dynamic range at the output. This is particularly important when operating in low supply voltages. The output voltage of CBM863X series can typically swing to less than 2mV from supply rail in light resistive loads (>100kΩ), and 60mV of supply rail in moderate resistive loads (10kΩ).
