Dual SP4T switch with -90 dB crosstalk floor
The MAX4052ACEE+: Each switch routes one of four inputs to a common output, or the reverse for demux operation. On-resistance is 100 Ohm max, with channel-to-channel matching held to 6 Ohm max — useful when gain or offset matching between channels matters in the signal path.
Supply rails and signal range
The single-supply range covers 3.3V and 5V logic rails; dual supplies let the switch handle bipolar signals without level shifting. Switching is fast — 175 ns turn-on, 150 ns turn-off max — so it tracks audio-rate or low-speed data multiplexing without introducing timing skew between channels. Charge injection is 2 pC typical, and off-leakage is 100 pA max. Channel capacitance is 2 pF on both source and drain sides, keeping the AC load light on upstream drivers.
Crosstalk and signal integrity
Crosstalk is rated -90 dB at 100 kHz — that is the isolation between channels when one is active and the others are off. For audio-frequency multiplexing or low-speed analog routing, the bleed between channels stays well below the noise floor of most 12-bit systems.
Housed in a 16-lead QSOP (3.90 mm wide body), surface-mount. Supplied in tube per the standard Analog Devices shipping format for this package variant.
