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 ? 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 mm 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

switching time (tON and tOFF less than 100 ns), excellent

Off-Isolation and Crosstalk (- 70 dB at 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.
