Quad SPST switch with 45 Ohm on-resistance and wide supply range
The DG412EUE+: It switches signals with a maximum on-resistance of 45 Ohm and channel-to-channel matching of 3 Ohm, keeping the insertion loss uniform across all four channels. The 1:1 multiplexer/demultiplexer circuit means each switch is a simple pass gate — no internal routing logic.
Switching speed and analog precision metrics
Maximum turn-on time is 175 ns and turn-off time is 145 ns — fast enough for audio multiplexing, sample-and-hold front-ends, or relay replacement in low-frequency switching applications. The charge injection of 5 pC sets the pedestal error when the switch opens; for a 1 kOhm load, that translates to roughly 5 mV of glitch, which matters in precision DAC output routing. Off-channel leakage is a maximum 250 pA at 25 °C, and the off-capacitance (CS(off), CD(off)) is 9 pF per node. Together they keep the signal feedthrough below -85 dB at 1 MHz, as listed in the crosstalk spec — this is the figure that matters when switching between analog channels in a mixed-signal system where isolation between paths is the performance limit.
No pin-compatible second source is listed on the manufacturer's cross-reference for this exact variant.
