Overview
The ADM8828ARTZ-REEL is a charge pump inverter switching voltage regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 1.5 V to 5.5 V and provides a negative output voltage ranging from -1.5 V to -5.5 V. The device delivers an output current of 25 mA with a fixed switching frequency of 120 kHz. It features a shutdown function and draws a static current of 600 uA, with a maximum operating supply current of 1 mA. The component is housed in a SOT-23-6 surface-mount package and supports operation temperatures from -40°C to +85°C.
Feature Summary
- Integrated charge pump topology for generating negative voltages from positive inputs
- Built-in shutdown control for power management optimization
- Compact SOT-23-6 surface-mount packaging for space-constrained designs
Applications
- RS-232 communication interface bias generation
- LCD display negative voltage supply
- Op-amp dual supply configuration
Procurement Notes
Verify the specific suffix REEL against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with SOT-23-6 footprint requirements during PCB layout. Cross-reference RoHS compliance details directly with the manufacturer's datasheet before procurement.
Selection Notes
Select this component when a compact solution is required to generate negative rails from single positive supplies. Consider the 25 mA output limit and 120 kHz switching frequency for noise-sensitive applications. Evaluate thermal performance within the specified -40°C to +85°C operating range for industrial environments.
Part Context
This part belongs to the ADM8828 series of charge pump inverters. It is designed as a PMIC solution for applications requiring small form factors. The device integrates all necessary components for inversion, minimizing external passive component count compared to discrete solutions.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Generic charge pump inverters may differ in efficiency or pinout compatibility.
