ADM8660AN

Overview

The ADM8660AN is a charge-pumped inverter integrated circuit manufactured by Analog Devices Inc. It operates within an input voltage range of 1.5 V to 7 V, providing an output voltage range of -7 V to -1.5 V. The device delivers up to 100 mA of output current through a single output channel. Key electrical parameters include a static current of 600 uA and a working supply current of 6.5 mA. The switching frequency is selectable between 25 kHz and 120 kHz. It functions within a temperature range of -40 C to +85 C and utilizes a SOIC-8 package.

Feature Summary

Integrates a shutdown pin to disable the device and reduce static current to 300 nA
Provides charge pump voltage inversion for generating negative supply rails from single positive sources
Features selectable operating frequencies to optimize external capacitor size and efficiency

Applications

Generating negative supply rails in single-supply systems
RS-232 interface power management
Op amp biasing requiring dual polarity supplies

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific suffix matches the required package type and thermal rating. Check datasheet revisions for any updates to electrical characteristics or recommended operating conditions before finalizing integration into the design.

Selection Notes

Select this component when a compact solution for voltage inversion is required with low quiescent current. Consider the trade-off between capacitor size and static current based on the chosen switching frequency. Ensure the load current does not exceed the 100 mA limit while maintaining acceptable ripple specifications.

Part Context

This part belongs to the ADM8660 series of CMOS switch-capacitor voltage converters. It serves as a direct replacement for older technologies like the ICL7660, offering improved performance and lower power consumption. The series includes variants such as the ADM660 for voltage doubling applications.
