MAX4659ESA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4659ESA+ is a single SPDT CMOS analog switch in an 8-pin SO package. It supports dual supplies from ±4.5V to ±20V and single supplies from +9V to +40V. The device features a maximum on-resistance of 25Ω at ±15V supplies, with a maximum flatness of 1.5Ω. It handles up to 75mA continuous current and 150mA peak current. Key dynamic parameters include a -3dB bandwidth of 225MHz, off-isolation of -70dB at 1MHz, and charge injection of 1.5pC. Operating temperature range is -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'ESA+' corresponds to the standard 8-pin SOIC package with the specified operating temperature range. Confirm that the component meets RoHS compliance requirements for the intended assembly process. Ensure the ordering documentation matches the manufacturer's part number format exactly to avoid substitution errors.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single-pole double-throw configuration is required for medium-voltage applications. It is suitable for designs needing high continuous current handling up to 75mA. Consider the 25Ω on-resistance and 225MHz bandwidth for signal integrity requirements. Verify that the supply voltage range aligns with the system's available power rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX4659/MAX4660 family of high-current analog switches. It is pin-compatible with legacy parts like the DG419 and MAX319. The MAX4660 variant offers higher current ratings but shares the same functional interface. The MAX4659 is designed for applications requiring robust switching performance in a compact surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG419 and MAX319 are confirmed pin-compatible replacements. Verify that substitute components meet the same current and resistance specifications.
