Overview
The ADM8660ARZ is a charge pump switching voltage regulator manufactured by Analog Devices Inc., housed in an 8-SOIC surface-mount package. It operates with an input voltage range of 1.5 V to 7 V and delivers a maximum output current of 100 mA. The device supports inverting topologies, providing negative output voltages from -7 V to -1.5 V, or positive outputs ranging from 5 V to 14 V. Key electrical parameters include a static current of 600 uA and a switch frequency between 25 kHz and 120 kHz. It functions within a temperature range of -40 C to +85 C and includes shutdown capability.
Feature Summary
- Integrates a charge pump topology for efficient voltage inversion and boosting without requiring external inductors.
- Features a dedicated shutdown pin to minimize power consumption during inactive periods.
- Supports flexible output configurations for both negative and positive voltage generation.
Applications
- Systems requiring negative supply rails for operational amplifiers
- RS-232 communication interface circuits
- Battery-powered instrumentation with low quiescent current requirements
Procurement Notes
Verify the specific suffix (REEL vs standard) against the required packaging format, as reel versions may differ in shipping units. Confirm RoHS compliance status through official documentation prior to integration. Ensure the SOIC-8 footprint matches the design layout exactly. Cross-reference the datasheet for thermal pad requirements if applicable to the specific revision.
Selection Notes
Select this component when a compact solution for generating negative voltages from a single low-voltage source is needed. Compare the 600 uA static current against system sleep requirements. Evaluate the 100 mA output limit against peak load demands. Consider the 25 kHz to 120 kHz frequency range for EMI sensitivity in nearby analog circuits.
Part Context
This part belongs to the ADM8660 series of charge pump inverters. It shares architectural similarities with the ADM660 but includes additional control features like shutdown functionality. The series is designed for applications where space constraints prohibit the use of magnetic components while maintaining stable voltage regulation.
Replacement Considerations
The ADM660ARZ is a related variant within the same family. Verify functional equivalence regarding the shutdown feature and output specifications before substitution. Check package dimensions and pinout compatibility to ensure mechanical fit.
