This product is a switched-capacitor voltage inverter which may be used to generate a negative supply from a positive input. Input voltages ranging from +1.5 V to +5.5 V can be inverted into a negative –1.5 V to –5.5 V output supply.
The ADM8828/ADM8829 is a switched‑capacitor charge‑pump voltage inverter that generates a negative supply from a positive input ranging from +1.5 V to +5.5 V. It delivers up to 25 mA output current with over 99 % conversion efficiency and includes a low‑power shutdown pin that reduces quiescent current to 20 nA.
The device is offered in a 6‑lead SOT‑23 (RT‑6) package and requires only two external capacitors. Detailed specifications, typical performance curves, and mechanical dimensions are provided, along with guidance on capacitor selection and shutdown operation.
