Overview
The ADM660ARZ-REEL7 is a CMOS switch-capacitor voltage converter manufactured by Analog Devices Inc., housed in an 8-pin SOIC package. It operates within an input voltage range of 1.5V to 7V, providing either inverted (-VIN) or doubled (2×VIN) output configurations with a maximum output current of 100mA. The device features a typical quiescent current of 600µA and supports selectable charge pump frequencies of 25kHz or 120kHz via the FC pin. Operating temperatures span from -40°C to +85°C.
Feature Summary
- Integrates voltage inversion and doubling functions using a CMOS switch-capacitor topology without requiring inductors.
- Offers selectable operating frequencies to optimize the trade-off between external capacitor size and quiescent current consumption.
- Provides direct pin-compatible replacement for legacy MAX660, MAX665, and ICL7660 devices.
Applications
- Generating negative supply rails for operational amplifiers in single-supply systems
- Creating boosted positive voltages for applications requiring higher potential than the input source
- Portable instrumentation and data acquisition systems requiring compact power management
Procurement Notes
Verify the specific suffix REEL7 confirms tape-and-reel packaging when ordering. Confirm the SOIC-8 package width matches your PCB footprint requirements. Ensure the selected frequency configuration aligns with your external capacitor selection strategy. Validate that the input voltage range covers your system's minimum operating conditions.
Selection Notes
Select this component when inductor-based converters are unsuitable due to noise or space constraints. Choose the 25kHz setting if larger capacitors are acceptable for lower static current. Opt for 120kHz operation to minimize external capacitance requirements. Ensure the load current remains within the 100mA limit to maintain specified efficiency levels.
Part Context
This part belongs to the ADM660 series of charge pump voltage converters. It serves as a modern CMOS alternative to older bipolar technologies, offering improved power efficiency and smaller form factors. The device is designed for industrial temperature ranges and complements Analog Devices' portfolio of precision power management solutions.
Replacement Considerations
The ADM660ARZ-REEL7 is documented as a pin-compatible upgrade for MAX660, MAX665, and ICL7660. Verify pinout compatibility before substitution. Note that the ADM8660 variant includes a shutdown pin but lacks the voltage doubling function found in the ADM660.
FAQ
How is the charge pump frequency selected?
The frequency is selected using the FC (Frequency Control) input pin, allowing the user to choose between 25kHz and 120kHz modes.
What is the difference between the ADM660 and ADM8660?
The ADM660 supports both voltage inversion and doubling, while the ADM8660 only performs inversion and includes a shutdown pin instead of the oscillator control pin.
