Product details

Package and mounting

The 300 MHz bandwidth passes signals up to that frequency with only 3 dB of roll-off. The -90 dB crosstalk at 1 MHz means adjacent channels won't bleed into each other.

Package and layout notes

The part comes in a 24-TQFN (4x4 mm) with an exposed pad. Surface-mount only.

Lifecycle and sourcing

The MAX4948ETG+ carries an Active lifecycle status from Analog Devices — no end-of-life notice, no last-time-buy window to chase. It is ROHS3 compliant, so it passes the usual EU material restrictions without an exemption.

Frequently asked questions

What is the -3dB bandwidth of MAX4948ETG+?

The -3 dB bandwidth is 300 MHz, which means the switch passes signals up to that frequency with only 3 dB of attenuation. This is well above the needs of video, 100BASE-TX, or audio muxing.

What is the on-resistance of MAX4948ETG+?

The maximum on-resistance is 5.5 ohms. Channel-to-channel matching is within 300 milliohms, so the path impedance stays consistent across all six SPDT switches.

Does MAX4948ETG+ come in tape and reel packaging?

The listed package is Tube. The tape-and-reel variant is typically ordered as MAX4948ETG+T — confirm the suffix when placing your order if your assembly line requires reel feed.
