The on-resistance profile is very flat over the full analog input range, ensuring excellent linearity and low distortion when switching audio signals. The ADG5404 is designed on a trench process, which guards against latch-up. A dielectric trench separates the P and N channel transistors, thereby preventing latch-up even under severe overvoltage conditions. The ADG5404 switches one of four inputs to a common output, D, as determined by the 3-bit binary address lines, A0, A1, and EN. Logic 0 on the EN pin disables the device. Each switch conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. All switches exhibit break-before-make switching action. PRODUCT HIGHLIGHTS 1. T...
