DESCRIPTION

The DG2715, DG2716 are low voltage, single supply, dual

SPST analog switches. Designed for high performance

switching of analog signals, the DG2715/2716 provide low

on-resistance (0.4 ? at + 2.7 V), fast speed (tON, tOFF at

17 ns and 14 ns) and the ability to handle signals over the

entire analog voltage range.

When operated on a + 3 V supply, control pins are

compatible with 1.8 V digital logic. Additionally,

on-resistance flatness and matching (0.05 ? and 0.1 ?) offer

high accuracy between channels.

Built on Vishay Siliconix’s low voltage submicron CMOS

process, the DG2715, DG2716 were designed to offer

solutions that extend beyond audio/video functions, to

providing the performance required for today’s demanding

mixed-signal switching in portable applications.

The DG2715 contains a normally open (NO) switch, and the

DG2716 contains a normally closed switch. An epitaxial

layer prevents latch-up. All switches conduct equally well in

both directions when on, and block up to the power supply

level when off.

As a committed partner to the community and the

environment, Vishay Siliconix manufactures this product

with the lead (Pb)-free device terminations. For analog

switching products manufactured with 100 matte tin

device terminations, the lead (Pb)-free “-E3” suffix is being

used as a designator.
