It delivers up to 10 mA per rail, switching at 8 kHz, and comes in an 8-SOIC package. ## 10 mA output — sizing the load The 10 mA per-rail limit is the hard constraint. Exceed 10 mA and the output voltage droops — the part has no synchronous rectifier, so efficiency drops with load. ## 8 kHz switching — capacitor selection and ripple At 8 kHz, the flying capacitor and output reservoir capacitor dominate ripple. Typical application circuits use 10 µF electrolytic or tantalum on both the input and output. The ripple frequency is 8 kHz, so a ceramic with low ESR in parallel helps knock down high-frequency hash. Keep the flying capacitor close to the IC — trace inductance at 8 kHz is manageable, but long loops couple switching noise into the load. ## Package and ordering code The MAX680CSA+T is the tape-and-reel variant of the SOIC-8 MAX680CSA. The +T suffix means it ships on a reel. Cut Tape (CT) is also available for prototype or small-batch builds. ## Lifecycle and sourcing The MAX680CSA+T is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect. The part is available through independent distribution and is quoted to order against an RFQ — current pricing and lead time are confirmed at quote time.","metaTitle":"MAX680CSA+T Charge Pump IC, 8kHz, 10mA, 8-SOIC","metaDescription":"MAX680CSA+T charge pump IC from Analog Devices.
