DESCRIPTION

The DG2017 is a dual DPDT (double-pole/double-throw),

optimized for high performance analog switching, and

specifically designed to benefit portable audio applications.

One pair of double-throw switches is sub 1

W for low

impedance speaker performance while the second pair of

double-throw switches is suitable for microphone applications.

With the DPDT configuration, the DG2017 provides the

flexibility for stereo-single-end or differential BTL output

structures with a fully integrated differential microphone

switching solution.

The DG2017 is an integrated monolithic device in a QFN-16

(4 x 4 mm) package that provides a space saving solution over

the use of multiple single SPDT devices as well as providing

the advantage of on-resistance flatness and matching that

single SPDT devices cannot offer.

The DG2017 provides low charge injection (2 pC), fast

Off-Isolation and Crosstalk (–70 dB @ 100 kHz).

During

operation, continuous current through any or all switches is

rated at

"200 mA, ideal for portable audio applications.

Built on Vishay Siliconix’s low voltage CMOS process, the

DG2017 contains an epitaxial layer that prevents latchup.

Break-before-make is guaranteed. When on, each switch

conducts equally well in both directions, and block up to the

power supply level when off.
