ADM660ARUZ-REEL

Overview

The ADM660ARUZ-REEL is a CMOS switched-capacitor voltage converter manufactured by Analog Devices Inc. It operates as a charge pump capable of inverting the input supply voltage to generate a negative rail or doubling it for higher positive output. The device accepts an input voltage range from +1.5 V to +7 V, providing an inverted output of -1.5 V to -7 V or a doubled output up to 14 V. It delivers an output current of 100 mA with a quiescent current of 600 µA. The switching frequency is selectable between 25 kHz and 120 kHz via the FC pin, allowing optimization of external capacitor size. The component is housed in a 16-lead TSSOP package.

Feature Summary

• Capable of inverting input voltage to create negative rails or doubling input voltage for increased positive output
• Features selectable charge pump operating frequencies to optimize external component sizing
• Utilizes low-power CMOS technology for efficient operation with minimal static current consumption

Applications

• Handheld Instruments
• Portable Computers
• Remote Data Acquisition
• Op Amp Power Supplies

Procurement Notes

Verify that the specific suffix REEL indicates tape-and-reel packaging rather than tube packaging when sourcing components. Confirm the manufacturing date code and lot traceability requirements against project specifications. Ensure the receiving facility has appropriate ESD protection protocols during handling. Cross-reference the ordering part number with the official Analog Devices distributor list to confirm availability status.

Selection Notes

Select this component when a single-supply system requires a negative voltage rail or a boosted positive voltage without using an inductor-based regulator. Consider the selectable frequency feature if board space for capacitors is limited, as the higher frequency allows for smaller capacitance values. Evaluate the 100 mA output current capability against the maximum load requirements of the target application circuitry.

Part Context

This component belongs to the ADM660 family of CMOS switched-capacitor voltage converters. It serves as a pin-compatible upgrade for legacy devices such as the MAX660, MAX665, and ICL7660. The family includes variants like the ADM8660, which offers a shutdown function but lacks the voltage doubling capability found in the ADM660 series.

Replacement Considerations

Publicly confirmed pin-compatible substitutes include the MAX660, MAX665, and ICL7660.
