Vishay Intertechnology, Inc. Analog Switches, Multiplexers, Demultiplexers DG2748DN-T1-E4

The DG2748DN-T1-E4 is a dual SPST analog switch designed for low on-resistance applications, featuring a typical on-resistance of 0.4 Oc at 2.7 V and 0.3 Oc at 4.3 V. It operates within a voltage range of 1.6 V to 4.3 V and is compatible with low voltage digital control circuits, requiring a logic high of 1.4 V. The device exhibits excellent performance metrics, including -72 dB off-isolation and -100 dB crosstalk at 100 kHz, making it suitable for high-fidelity audio applications. The switch has a -3 dB bandwidth of up to 93 MHz and a total harmonic distortion of 0.03% across a frequency range of 20 Hz to 20 kHz. Housed in a compact miniQFN-8 package measuring 1.4 x 1.4 x 0.55 mm, the DG2748DN-T1-E4 is ideal for space-constrained applications such as portable media players, cellular phones, and medical equipment. The product is RoHS compliant and features lead-free terminations, ensuring environmental safety.
