Overview
The ADM8829ART-REEL7 is a single-channel charge pump inverter integrated circuit manufactured by Analog Devices. It operates within an input voltage range of 1.5 V to 5.5 V and delivers a negative output voltage between -1.5 V and -5.5 V with a maximum output current of 25 mA. The device features a fixed switching frequency of 120 kHz and includes a shutdown control function. It is housed in a compact SOT-23-6 surface-mount package and supports operation across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Inverts positive supply voltages to generate negative rails for powering analog circuits
- Integrates a shutdown pin to minimize power consumption during inactive periods
- Utilizes a fixed-frequency charge pump topology for stable voltage conversion
Applications
- Generating negative bias voltages for operational amplifiers
- Powering RS-232 transceivers and interface drivers
- Providing dual-polarity supplies for sensor signal conditioning
Procurement Notes
Verify the exact suffix against official documentation, as 'REEL7' denotes specific packaging. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as availability may be restricted. Ensure the component matches the required SOT-23-6 footprint and electrical specifications for your design.
Selection Notes
Select this component when a compact solution is needed to create a negative voltage rail from a single positive source. Consider the 25 mA output limit and 120 kHz switching frequency for noise-sensitive applications. Verify that the input voltage range aligns with the system's power supply capabilities.
Part Context
This part belongs to the ADM8829 series of switched-capacitor voltage converters. It is designed for portable electronics and battery-powered devices requiring efficient voltage inversion without the use of inductors. The series focuses on low component count and small physical footprint.
Replacement Considerations
Check for ADM8829ARTZ variants which may offer updated environmental compliance. Consult Analog Devices documentation for direct pin-compatible alternatives within the same family.
