DG2017_11 Datasheet, PDF (1/11 Pages) Vishay Siliconix – Low-Voltage, Low RON, Dual DPDT Analog Switch

DG2017
Vishay Siliconix
Low-Voltage, Low R_ON, Dual DPDT Analog Switch
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 (t_ON and t_OFF 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.
