ICL7662EWA

Encoders, Decoders, Converters Overview

The ICL7662EWA is a monolithic high-voltage CMOS power supply circuit manufactured by Harris Corporation. It functions as a switched capacitor converter, performing supply voltage conversion from positive to negative for an input range of +4.5V to +20.0V. This results in complementary output voltages ranging from -4.5V to -20V. The device requires only two noncritical external capacitors for charge pump and reservoir functions. It can also operate as a voltage doubler. The component is designed for applications requiring simple conversion of standard supplies or negative supplies for instrumentation.

Encoders, Decoders, Converters Feature Summary

• Monolithic high-voltage CMOS construction
• Positive to negative voltage conversion capability
• Voltage doubling functionality
• Minimal external component requirement

Encoders, Decoders, Converters Applications

• Simple conversion of +5V to ±5V supplies
• Negative supplies for data acquisition systems
• Instrumentation power requirements
• RS232 power supplies

Encoders, Decoders, Converters Procurement Notes

Verify the specific suffix 'EWA' against official Harris or Maxim Integrated datasheets, as standard listings often cite 'ICL7662CBA+' or 'ICL7662CBD'. Confirm RoHS compliance status and package type (typically SOIC-8 or DIP-8) with the supplier. Ensure the source document explicitly identifies the manufacturer as Harris Corporation rather than a generic distributor listing.

Encoders, Decoders, Converters Selection Notes

Select this component when a single-supply system requires a negative rail without using an inductor-based switching regulator. It is suitable for low-current applications up to 20mA. Consider the 10kHz switching frequency for noise-sensitive designs. Verify that the external capacitor values meet the stability requirements for the chosen load current and input voltage range.

Encoders, Decoders, Converters Part Context

The ICL7662 series represents a family of CMOS voltage converters originally developed by Harris Semiconductor, which was later acquired by Maxim Integrated and subsequently Analog Devices. The 'ICL' prefix typically denotes integrated circuit logic products from Harris. This specific model is part of the legacy portfolio used in industrial and instrumentation control systems.

Encoders, Decoders, Converters Replacement Considerations

Publicly confirmed substitute part numbers include ICL7660, ICL7661, and ICL7662 variants such as ICL7662CBA+ or ICL7662CBD. Verify pin compatibility and electrical specifications before substitution.
