Signal routing with sub-ohm on-resistance
The NX3L2467GU,115 is a dual DPDT analog switch from NXP, integrating two independent DPDT switches in a single 16-XFQFN package. Each switch handles signal paths with a maximum on-resistance of 750mOhm, keeping insertion loss low in audio and low-frequency analog chains. Channel-to-channel matching is held to 70mOhm max, so the resistance variation between the two poles within a switch stays tight — important for maintaining balanced attenuation in stereo audio or differential signal paths.
Bandwidth and isolation for mixed-signal boards
The -3dB bandwidth of 60MHz means the switch passes audio, baseband video, and many control signals without significant roll-off. Crosstalk is rated at -90dB at 100kHz, which keeps channel bleed below the noise floor in sensitive analog multiplexing applications. Switching times are 40ns on and 20ns off, fast enough for audio source selection or signal routing in portable devices where glitch-free transitions matter. Charge injection is 15pC typical, a figure to consider in high-impedance sample-and-hold front-ends. Leakage current is max 10nA off-state, and channel capacitance is 35pF — both low enough to avoid loading the signal source in most audio and control circuits.
NXP lists the NX3L2467GU,115 as Active in production.
16-XFQFN footprint for space-constrained boards
Housed in a 16-XFQFN package measuring 1.8x2.6mm (supplier device package 16-XQFN), this switch fits into tight PCB layouts typical of handheld or portable equipment. Surface-mount assembly with a 0.5mm pitch requires standard reflow profiling.
