It accepts an input voltage from 2V to 6V and delivers a fixed output of ±2× the input voltage. Each of the two outputs is rated for 10 mA continuous, making this part suitable for biasing op-amp rails, LCD contrast supplies, or small sensor circuits where a split supply is required from a single battery or 5V rail. The switching frequency is fixed at 8 kHz — low enough to keep external capacitor sizes modest (typically 10 µF) and minimise radiated noise in sensitive analog paths. ## Package and temperature grade The footprint is standard SOIC-8, compatible with many second-source charge pump ICs. Rated for the commercial temperature range of 0°C to 70°C, this part is intended for indoor or controlled-environment equipment — not for automotive or extended industrial use. ## Lifecycle and ordering posture ROHS3 compliant, it meets current environmental regulatory requirements for European and global markets. Sourced per RFQ — confirm the BOM quantity and preferred lead time with your account representative.","metaTitle":"MAX680CSA+ Charge Pump IC – Analog Devices, 8-SOIC, Active","metaDescription":"MAX680CSA+ from Analog Devices: charge pump DC-DC converter, 2V to 6V input, ±2Vin output, 10mA, 8kHz, SOIC-8.
