Malvern, Pa. Vishay Intertechnology, Inc. has released eight high-frequency, low-charge-injection analog multiplexers and switches for precision instrumentation applications. Vishay claims these are the first devices of their kind to be offered in the leadless 1.8 x 2.6-mm miniQFN package, in addition to the standard TSSOP and SOIC
The four analog multiplexers and four 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 ohms to 72 ohms.
These specifications make them well-suited for high-frequency analog switching, high-speed multiplexing, audio and video routing, filtering, gain and frequency selection, level shifting, and calibration. End products include precision instrumentation, industrial controls, medical instrumentation, telecom and datacom equipment, automated test equipment (ATE), and high-speed communications systems.
The 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 DG636 can be used as a dual SPDT analog switch or dual 2:1 multiplexer.
All of the devices are designed to operate from a +2.7-V to +12-V single supply, or from +/-2.5-V to +/-5.0-V dual supplies. They are fully specified at +3 V, + 5 V, and +/-5 V. All control logic inputs have guaranteed 2-V logic high limits when operating from + 5-V or +/-5-V supplies, and are low-voltage logic compatible when operating from a 3-V supply.
The multiplexers and switches conduct equally well in both directions and offer rail-to-rail analog signal handling. They feature an extended operating temperature from -40° to +125°, and are available in a variety of packages including the 14- and 16-lead TSSOP, 16-pin narrow SOIC, and the miniQFN.
Pricing: Ranges from $0.75 to $0.85 for U.S. delivery.
Availability: Samples and production quantities are available now, with lead times of six to eight weeks for larger orders.
