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, and fast 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 V and 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.
