DG2727, DG2728, DG2729
Vishay Siliconix
0.65-Ω, Low Voltage, Negative Swing Capable,
Dual SPST Analog Switch
DESCRIPTION
The DG2727, DG2728, and DG2729 are 0.6 Ω dual SPST
analog switches. When Sx are used as signal input, these
devices support AC-coupled audio signals with single rail
power supply. Audio signals can swing below ground down
to V+ - 4.3 V.
Built on Vishay Siliconix’s sub-micro CMOS technology, the
DG2747/2748/2749 achieve 0.6 Ω on-resistance and 0.2 Ω
flatness at 2.7 V power supply. Its total harmonic distortion is
0.006 % (frequency ranges 20 Hz to 20 kHz).
It achieves - 72 dB off-isolation and - 100 dB crosstalk at
100 kHz. Its - 3 dB bandwidth is up to 78 MHz.
Select pin of control logic can tolerate voltage above power
supply up to 4.3 V. It has guaranteed 1.2 V logic high for the
power supply 2.7 V to 4.3 V range. This makes it compatible
with many low voltage digital control circuits.
Combining wide operation voltage, low power, high speed,
low on-resistance and small physical size, the DG2747,
DG2748, DG2749 are ideal for portable and battery powered
applications requiring high performance and efficient use of
board space.
The DG2747, DG2748, DG2749 come in a small
miniQFN-8L package (1.4 mm x 1.4 mm x 0.55 mm) and
operate over - 40 °C to + 85 °C extended temperature range.
FEATURES

x 0.55 mm
• High fidelity audio switch
• Reed relay replacement
• Low power consumption
APPLICATIONS
• Cellular phones
• GPS and portable media player
• Audio and video signal routing
• Modems
• Hard drives and computer peripherals
• Low voltage data-acquisition circuits
• Medical and test equipment
