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
Halogen-free according to IEC 61249-2-21
definition
Wide operation voltage range: 1.6 V to 4.3 V
Low 0.6
Ω (typical at 2.7 V) on-resistance
Guaranteed logic high threshold:
Vth(high) = 1.2 V at V+ = 4.3 V
- 82 dB crosstalk and - 76 dB off-isolation at 100 kHz
250 MHz, - 3 dB bandwidth
0.006 % total harmonic distortion
> 250 mA latch up current per JESD78
> 8 kV ESD/HBM per MIL-STD 883 (method 3015)
Compliant to RoHS directive 2002/95/EC
