Single 4:1 Low rON Multiplexers
DG2034
Vishay Siliconix
DESCRIPTION
The DG2034 is a low voltage, low rON, high bandwidth single
4 to 1 analog multiplexer designed for high performance
switching of analog and video signals. Combining low power;
fast switching; low on-resistance, flatness and matching; and
small physical size, the DG2034 is ideal for portable and
battery applications.
Built on Vishay Siliconix’s low voltage CMOS process, the
DG2034 has an epitaxial layer which prevents latchup.
Break-before-make is guaranteed.
FEATURES
• Low voltage operation (1.8 V to 5.5 V)
• Low on-resistance - rDS(on): 4 Ω
• Off-isolation and crosstalk: - 55 dB at 10 MHz
• Fast switch - 25 ns tON
• Low charge injection - QINJ: 4.7 pC
• Low power consumption - 4 µW
