MAX4572CWI

Analog Switches - Special Purpose Overview

The MAX4572CWI is a video switch IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features a configuration of two SPST and six SPDT switches within a single package. The device operates on a single supply voltage ranging from 2.7 V to 5.25 V, with a typical operating voltage of 5 V. Key electrical parameters include a maximum on-resistance of 35 Ohms, a bandwidth of 150 MHz, and a maximum turn-on time of 8 ns. The component supports a maximum DC switch current of 10 mA and dissipates up to 860 mW of power. It is housed in a QSOP-28 surface-mount package and functions within an operating temperature range of 0°C to +70°C.

Analog Switches - Special Purpose Feature Summary

• Serially controlled architecture for efficient pin usage
• Clickless audio/video switching capability
• High bandwidth suitable for video signal routing

Analog Switches - Special Purpose Applications

• Video signal routing systems
• Audio distribution networks
• Test and measurement equipment

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status through the manufacturer's latest datasheet. Ensure the source provides valid traceability for the Analog Devices/Maxim Integrated part number before procurement.

Analog Switches - Special Purpose Selection Notes

Select this component when a mixed configuration of SPST and SPDT switches is required in a compact form factor. Verify that the 150 MHz bandwidth meets the signal frequency requirements. Check that the 35 Ohm on-resistance is acceptable for the application's signal integrity needs.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4572 series of serially controlled video switches. It is distinct from the MAX4570 and MAX4571 series which offer different switch configurations. The CWI suffix typically denotes a wide-body SOIC package variant, differing from the CEI QSOP version.

Analog Switches - Special Purpose Replacement Considerations

The MAX4572CEI+T is a verified substitute with identical functionality but in a QSOP-28 package. Verify pin compatibility and thermal characteristics when substituting between SOIC and QSOP packages.
