The Vishay DG9233EDY-GE3 is a dual SPST-NO (Single-Pole Single-Throw, Normally Open) analog switch in an 8-SOIC surface-mount package. Each switch has a 1:1 multiplexer/demultiplexer configuration, meaning it connects a single input to a single output per channel. On-resistance is 25 Ohm maximum, with channel-to-channel matching of 400 mOhm — this tight matching keeps the insertion loss consistent across both channels in precision signal routing. Switching times are 75 ns (turn-on) and 50 ns (turn-off) maximum, suitable for audio, data acquisition, and low-frequency analog multiplexing where signal integrity matters more than nanosecond-level throughput.
Supply and signal integrity
Charge injection is -0.78 pC typical — low enough that the injected charge causes negligible voltage glitch on the switched signal when the switch opens or closes. Leakage current is 100 pA maximum in the off state, preserving accuracy in high-impedance circuits. Crosstalk between channels is -108 dB at 1 MHz, indicating strong isolation — a signal on one channel couples less than 0.0004% (-108 dB) to the other at that frequency, important for maintaining channel separation in audio or multi-sensor front ends. Channel capacitance (CS(off), CD(off)) is 3.8 pF, which limits the bandwidth in the off state but keeps the capacitive loading low on the signal path.
Surface-mount assembly requires no special handling beyond standard MSL precautions.
Lifecycle and compliance
