DG2748 Overview
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 kHz).
DG2748 Key Features
- Wide operation voltage range: 1.6 V to 4.3 V
