6-Ω, Low Voltage, Dual SPST Analog Switch
DESCRIPTION
The DG2737, DG2738 and DG2739 are high performance,
low on-resistance analog switches of dual SPST
configuration.
Built on Vishay Siliconix's sub-micro CMOS technology, the
DG2737, DG2738, DG2739 achieve switch on-resistance of
6 Ω at 3 V V+. Its - 3 dB bandwidth is typically 720 MHz.
It can switch signals with amplitudes of up to VCC to be
transmitted in either direction.
Combining low power, high speed, low on-resistance and
www.DastmaaShllepehty4sUic.caol msize, the DG2737, DG2738, DG2739 are ideal
for portable and battery powered applications requiring high
performance and efficient use of board space.
The DG2737, DG2738, DG2739 come in a small miniQFN-8
lead package (1.4 x 1.4 x 0.55 mm). As a committed partner
to the community and the environment, Vishay Siliconix
manufactures this product with the lead (Pb)-free device
terminations and is 100 % RoHS compliant.
FEATURES
• Voltage range: 2.3 V to 4.3 V
• Low on-resistance: 6 Ω typ. at 3 V
• - 48 dB crosstalk at 240 MHz
• Low power consumption
RoHS
COMPLIANT
• Ultra small miniQFN8 package of 1.4 x 1.4 x 0.55 mm
• > 300 mA latch up current per JESD78
• Switch exceeds 5 kV ESD/HBM
