.Data Sheet.co.kr DG2747, DG2748, DG2749 Vishay Siliconix 0.4-Ω, Low Voltage, Dual SPST Analog Switch DESCRIPTION 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, DG2748, DG2749 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 k Hz). It achieves - 72 d B off-isolation and - 100 d B crosstalk at 100 k Hz. Its - 3 d B bandwidth is up to 93 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 patible with many low voltage digital control circuits. bining 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 e in a small mini QFN-8 lead package (1.4 x 1.4 x 0.55 mm). As a mitted partner to the munity and the environment, Vishay Siliconix manufactures this product with the lead (Pb)-free device terminations and is 100 % Ro HS pliant.
