Product details

Six SPDT channels in a 4x4 mm package

The Analog Devices MAX4948ETG+T packs six independent SPDT switch circuits into a 24-TQFN (4x4) package, each channel rated for 1.8 V to 5.5 V single-supply operation. With a maximum on-resistance of 5.5 Ω and channel-to-channel matching held to 300 mΩ, this part is suited for precision analog signal routing where consistent insertion loss across channels matters. The -3 dB bandwidth reaches 300 MHz, making it usable for video or high-speed data paths, while -90 dB crosstalk at 1 MHz keeps channel isolation clean for mixed-signal boards where a switched ADC input or audio line sits next to a digital control line.

Switching speed and signal integrity

Turn-on and turn-off times are matched at 800 ns each. Charge injection is 10 pC.

Lifecycle and sourcing

This part carries an Active lifecycle status from the manufacturer with ROHS3 compliance. No last-time-buy or end-of-life notices are in effect, making it suitable for both new design-ins and ongoing production builds.

Frequently asked questions

Is MAX4948ETG+T obsolete or end-of-life?

No — the manufacturer lists MAX4948ETG+T as Active with ROHS3 compliance. No EOL or last-time-buy status is published, so it is suitable for new designs and production builds.

What are the direct alternatives or replacements for MAX4948ETG+T?

Within the same Analog Devices portfolio, the MAX4948 shares the same 6-channel SPDT architecture and 5.5 Ω on-resistance with a 300 MHz bandwidth. Pin-compatibility across the family should be verified against the specific package variant — the MAX4948ETG+T uses a 24-TQFN (4x4) footprint. For a second-source evaluation, compare on-state resistance, bandwidth, and crosstalk against the listed specs.

What is MAX4948ETG+T's listed crosstalk (-90dB @ 1MHz) on this component line?

The listed crosstalk is -90 dB at 1 MHz. This figure tells you channel-to-channel isolation is strong enough for a 1 MHz analog signal to not leak into an adjacent channel by more than about 31 µV for a 1 V signal — adequate for 12-bit ADC front-ends and audio line-level switching.
