Product details

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.

The footprint is standard SOIC-8, compatible with many second-source charge pump ICs.

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.

Frequently asked questions

Can the MAX680CSA+ generate both positive and negative voltages?

Yes, it has two outputs configured as positive and negative rails (dual-rail output). The positive output is +2×Vin, the negative output is -2×Vin.

What is the output current rating of the MAX680CSA+?

Each output is rated for 10 mA continuous. The total load across both rails should not exceed this per-output limit.

Does the MAX680CSA+ require external capacitors?

Yes, as a charge pump it needs external capacitors for the flying and reservoir stages. Typical values are 10 µF, but the datasheet provides the full selection guidance.
