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

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

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).
