Charge pump with dual-rail output
The MAX680CSA+ is a charge pump DC-DC converter from Analog Devices that generates both positive and negative output rails from a single input supply — no inductor needed. 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.
