Vishay Releases Analog Multiplexers and Switches

Vishay Intertechnology Inc. has released eight charge-injection analog multiplexers and switches for precision instrumentation applications. The devices are offered in the leadless 1.8-mm by 2.6-mm miniQFN package, in addition to the standard TSSOP and SOIC packages. The four analog multiplexers and four analog switches combine an ultra-low charge injection from 0.5pC to 1.0pC, low switch capacitance of 2pF and 3pF, leakage currents from 0.25nA to 5nA, and typical on-resistance from 66Ω to 72Ω. The specifications of devices are for analog switching, high-speed multiplexing, audio and video routing, filtering, gain and frequency selection, level shifting, and calibration. The multiplexer offering includes the 4-channel DG604, the dual 4-channel DG4052A, the 8-channel DG4051A, and the triple 2-channel DG4053A. The 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. They are specified at +3V, +5V, and ±5V. They feature an extended operating temperature from -40°C to +125°C, and are available in a variety of packages, including the 14- and 16-lead TSSOP, 16-pin narrow SOIC, and the space-saving miniQFN.
