The ADG5404 is a complementary metal-oxide semiconductor 1. Trench Isolation Guards Against Latch-Up. A dielectric (CMOS) analog multiplexer, comprising four single channels. trench separates the P and N channel transistors, thereby The on-resistance profile is very flat over the full analog input preventing latch-up even under severe overvoltage range, ensuring excellent linearity and low distortion when conditions. switching audio signals. 2. Low RON. 3. Dual-Supply Operation. For applications where the analog The ADG5404 is designed on a trench process, which guards signal is bipolar, the ADG5404 can be operated from dual against latch-up. A dielectric trench separates the P and N supplies of up to ±22 V. channel transistors, thereby preventing latch-up even under 4. Single-Supply Operation. For applications where the severe overvoltage conditions. analog signal is unipolar, the ADG5404 can be operated The ADG5404 switches one of four inputs to a common output, from a single-rail power supply of up to 40 V. D, as determined by the 3-bit binary address lines, A0, A1, and 5. 3 V logic-compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V. EN. Logic 0 on the EN pin disables the device. Each switch 6. No VL logic power supply required. conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condi- tion, signal levels up to the supplies are blocked. All switches exhibit break-before-make switching action.
