Vishay Intertechnology Inc. released three dual single pole double throw (SPDT) and dual double pole double throw (DPDT) CMOS low-voltage analog switches that combine low-voltage operation and low on-resistance in small miniQFN packages for audio, SIM card, and multi-purpose signal switching in space-constrained portable end products.
The DG2735A and DG2725 are dual SPDT switches in the miniQFN10 package, designed for an operating range of 1.65 V to 4.3 V. With its guaranteed low 0.6 Ω maximum on-resistance at 2.7 V, andfast turn-on time of 64 ns and turn-off time of 42 ns at 2.7 V, the DG2735A is well-suited for audio output switching in receivers and speakers. The DG2725 offers typical on-resistance of 0.7 Ω at 3 V, while providing lower parasitic capacitance.
The DG2599 has an operation voltage range of 1.65 V to 5 Vand can be used as a quad SPDT or dual DPDT switch . The device features the miniQFN16 package, on-resistance of 2.8 Ω typical at 3 V, and – 3dB bandwidth to 186 MHz. Both the DG2725 and DG2599 feature power off protection that guarantees < 1 µA COM1 and COM2 leakage, when V+ = 0 V and VCOM1 or VCOM2 = 4.3 V.
Pricing : For U.S. delivery in 1,000-piece quantities is $0.27 per piece for the DG2725, $0.31 for the DG2735A, and $0.40 for the DG2599.
Availability : Samples and production quantities of the new analog switches are available now, with a lead time of 10 weeks.
