DESCRIPTION
The DG2727, DG2728, and DG2729 are 0.6 Ω dual SPST analog switches. When Sx are used as signal input, these devices support AC-coupled audio signals with single rail power supply. Audio signals can swing below ground down to V+ - 4.3 V.
FEATURES
• Halogen-free according to IEC 61249-2-21 definition
• Wide operation voltage range: 1.6 V to 4.3 V
• Low 0.6 Ω (typical at 2.7 V) on-resistance
• Guaranteed logic high threshold: Vth(high) = 1.2 V at V+ = 4.3 V
• - 82 dB crosstalk and - 76 dB off-isolation at 100 kHz
• 250 MHz, - 3 dB bandwidth
• 0.006 % total harmonic distortion
• > 250 mA latch up current per JESD78
