www.corebai.com CBMLM321-CBMLM358-CBMLM324 OPERATION INSTRUCTION APPLICATION NOTES Size CBMLM358 family series op amps are unity-gain stable and suitable for a wide range of general-purpose applications. The small footprints of the CBMLM358 family packages save space on printed circuit boards and enable the design of smaller electronic products. Power Supply Bypassing and Board Layout CBMLM358 family series operates from a single 3V to 24V supply or dual ±1.5V to ±12V 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 250uA per channel) of CBMLM358 family will help to maximize battery life. Operating Voltage CBMLM358 family operates under wide input supply voltage (3V to 24V). In addition, all temperature specifications apply from -25 ℃ to +80℃. Most behavior remains unchanged throughout the full operating voltage range. These guarantees ensure operation throughout the single Li-Ion battery lifetime Capacitive Load Tolerance The CBMLM358 family is optimized for bandwidth and speed, not for driving capacitive loads. Output capacitance will create a pole in the amplifier’s feedback path, leading to excessive peaking and potential oscillation. If dealing with load capacitance is a requirement of the application, the two strategies to consider are (1) using a small resistor in series with the amplifier’s output and the load capacitance and (2) reducing the bandwidth of the amplifier’s feedback loop by increasing the overall noise gain. Figure 2. shows a unity gain follower using the series resistor strategy. The resistor isolates the output from the capacitance and, more importantly, creates a zero in the feedback path that compensates for the pole created by the output capacitance. A ll data sheet.com
