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
switching time (_tON and t_OFF less than 100 ns), excellent
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.
