MUXs and Switches Target Precision Instrumentation

New high-frequency analogue multiplexers and switches from Vishay Intertechnology are aimed at precision instrumentation applications. Featuring low charge injection, they are believed to be the first devices of their kind to be offered in the leadless 1.8mm x 2.6mm miniQFN package, in addition to the standard TSSOP and SOIC packages.



The four multiplexers and four switches combine 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 multiplexers are the four-channel DG604, the dual four-channel DG4052A, the eight-channel DG4051A, and the triple two-channel DG4053A.

The switches are the quad Single Pole Single Throw (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 fourth switch, the DG636, can be used as a dual Single Pole Double Throw (SPDT) switch or dual 2:1 multiplexer.

All of the devices are designed to operate from a single supply of 2.7V to 12V, or from ±2.5V to ±5.0V dual supplies. They are fully specified at +3V, +5V, and ±5V. All control logic inputs have guaranteed 2V logic high limits when operating from +5V or ±5V supplies, and are low-voltage logic compatible when operating from a 3V supply.

The components conduct equally well in both directions and offer rail-to-rail analogue signal handling. They feature an extended operating temperature from -40°C to +125°C. In addition to the miniQFN package, they are also available in 14-pin or 16-lead TSSOP, 16-pin narrow SOIC.
