Overview
The ADM8829ARTZ-REEL is a charged pump inverter integrated circuit manufactured by Analog Devices Inc. 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 switching frequency of 120 kHz and draws a typical operating supply current of 1 mA, with a quiescent current of 600 uA. It is housed in a SOT-23-6 package and supports surface mount installation. The component functions as a single-output switching voltage regulator designed for inverting topologies.
Feature Summary
- Provides inverting switched-capacitor voltage conversion from positive to negative rails
- Operates efficiently across a wide single-supply input voltage range
- Integrates shutdown functionality for power management control
Applications
- Biasing operational amplifiers requiring dual polarity supplies
- Powering RS-232 transceivers and interface circuits
- Generating negative gate drive voltages for N-channel MOSFETs
Procurement Notes
Verify the specific suffix REEL against official Analog Devices documentation to confirm packaging configuration and tape-and-reel specifications. Ensure compatibility with SOT-23-6 footprint requirements during PCB layout. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a compact solution is required to generate a stable negative voltage from a low-voltage positive source. Consider the 25 mA output current limit and 120 kHz switching frequency relative to external capacitor selection. Evaluate the 600 uA quiescent current against system standby power constraints compared to linear regulators or other charge pump alternatives.
Part Context
This part belongs to the ADM8829 series of micropower charged pump inverters. It is categorized under PMIC - Power Management ICs and specifically Switching Voltage Regulators. The device is designed for applications needing efficient voltage inversion without the complexity of inductor-based DC-DC converters.
Replacement Considerations
Check for direct pin-compatible substitutes within the Analog Devices portfolio that offer similar output current capabilities and voltage ranges. Verify if alternative packages such as SC-70 are available for space-constrained designs while maintaining electrical performance equivalence.
