Overview
The ADM8829ARTZ-REEL7 is a single-output inverting switch-mode DC/DC converter manufactured by Analog Devices Inc. It operates within an input voltage range of 1.5 V to 5.5 V and provides an adjustable output voltage between -1.5 V and -5.5 V. The device delivers up to 25 mA of output current with a typical quiescent current of 600 uA. It functions at a switching frequency of 120 kHz and includes a shutdown feature for power management. The component is housed in a SOT-23-6 package and supports operation temperatures from -40°C to +85°C.
Feature Summary
- Inverting topology generates negative voltage from positive supply
- Integrated charge pump circuitry for efficient conversion
- Shutdown pin enables low-power standby mode
Applications
- RS-232 transceiver bias generation
- Op-amp dual supply creation
- LCD bias voltage generation
Procurement Notes
Verify the specific suffix REEL7 against official Analog Devices documentation to confirm packaging specifications. Confirm RoHS compliance status through the manufacturer datasheet. Ensure the SOT-23-6 footprint matches your PCB design requirements before procurement.
Selection Notes
Select this component when a compact, low-cost solution for generating negative rail voltages is required. Consider the 25 mA current limit and 120 kHz switching frequency for compatibility with downstream circuit filtering needs. Evaluate the SOT-23-6 package size constraints relative to available board space.
Part Context
This part belongs to the ADM8829 series of charged pump inverters designed for portable applications. It serves as a power management IC (PMIC) within the broader Analog Devices portfolio, specifically targeting systems requiring small form factor solutions for signal conditioning or communication interfaces.
Replacement Considerations
Consult Analog Devices technical support for verified cross-reference part numbers. Do not assume functional equivalence with other inverting converters without validating electrical parameters and pin configurations.
