资料介绍
The DG2747, DG2748, and DG2749 are high performance,
low on-resistance analog switches of dual SPST
configuration.
Built on Vishay Siliconix's sub-micro CMOS technology, the
DG2747/2748/2749 achieve switch on-resistance of 0.4 Ω at
2.7 V V+ and 0.3 Ω at 4.3 V V+. It provides 0.1 Ω flatness at
2.7 V V+, and total harmonic distortion to 0.03 % (frequency
range 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.
It can switch signals with amplitudes of up to VCC to be
transmitted in either direction.
The select pins of the control logic can tolerate voltages
above V+. Logic high is 1.4 V to make 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 DG2747/2748/
2749 are ideal for portable and battery powered applications
requiring high performance and efficient use of board space.
The DG2747/2748/2749 come in a small miniQFN-8lead
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.
