MAX4638EGE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4638EGE is a single-channel, high-speed CMOS analog multiplexer switch manufactured by Analog Devices Inc. (Maxim Integrated). It features an 8:1 configuration housed in a 16-lead TQFN-EP package with exposed pad for surface-mount installation. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V or dual supplies up to ±2.75 V. Key electrical parameters include a maximum on-resistance of 6 Ohms, a bandwidth of 50 MHz, and a propagation delay of 18 ns. It supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• High-speed switching performance suitable for signal routing applications
• Low on-resistance characteristic ensuring minimal signal attenuation
• Compatible with low-voltage single and dual power supply systems

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring signal multiplexing
• Communication equipment for analog signal routing
• Industrial control systems utilizing sensor inputs

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EGE' against official manufacturer documentation to confirm the exact package type and tape-and-reel quantity specifications. Ensure compatibility with standard surface-mount assembly processes and check for RoHS compliance status in current datasheets before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single 8:1 mux is required with low on-resistance and high bandwidth. Compare against the MAX4638ESE variant if SOIC packaging is preferred over TQFN. Verify that the 6 Ohm on-resistance meets system requirements for signal integrity at the intended operating frequency.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4638 series of high-speed analog switches. It complements other devices in the family such as the MAX4618 and MAX4639, offering a balance between speed and on-resistance. The EGE designation specifically identifies the TQFN-EP-16 package variant within this product line.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4638ESE+ is a pin-compatible alternative in a 16-SOIC package. Verify thermal dissipation differences due to the exposed pad design in the EGE variant compared to the standard SOIC package.
