Vishay has released eight high-frequency, low charge injection analog multiplexers and switches for precision instrumentation applications. They are the first devices of their kind to be offered in the leadless 1.8-mm by 2.6-mm miniQFN package, in addition to the standard TSSOP and SOIC packages. The four new analog multiplexers and four new analog switches combine an ultra-low charge injection from 0.5 pC to 1.0 pC, low switch capacitance of 2 pF and 3 pF, leakage currents from 0.25 nA to 5 nA, and typical on-resistance from 66 Ω to 72 Ω. Their specifications make them ideal for high-frequency analog switching, high-speed multiplexing, audio and video routing, filtering, gain and frequency selection, level shifting, and calibration. The new multiplexer offering includes the 4-channel DG604, the dual 4-channel DG4052A, the 8-channel DG4051A, and the triple 2-channel DG4053A. The new analog switches are the quad SPST DG611A, DG612A, and DG613A, which offer improved charge injection, on-resistance, and standby current compared to the industry-standard DG611, while eliminating the need for a VL pin. The new DG636 can be used as a dual SPDT analog switch or dual 2:1 multiplexer.
