The ADG5408/ADG5409 are monolithic CMOS analog multi- The ADG5408/ADG5409 do not have VL pins; rather, the logic plexers comprising eight single channels and four differential power supply is generated internal y by an on-chip voltage channels, respectively. The ADG5408 switches one of eight generator. inputs to a common output, as determined by the 3-bit binary
PRODUCT HIGHLIGHTS
address lines, A0, A1, and A2. The ADG5409 switches one of four differential inputs to a common differential output, as 1. Trench isolation guards against latch-up. A dielectric trench determined by the 2-bit binary address lines, A0 and A1. separates the P and N channel transistors thereby preventing latch-up even under severe overvoltage conditions. An EN input on both devices enables or disables the device. 2. Low RON. When EN is disabled, all channels switch off. The on-resistance 3. Dual-supply operation. For applications where the analog profile is very flat over the full analog input range, which ensures signal is bipolar, the ADG5408/ADG5409 can be operated good linearity and low distortion when switching audio signals. from dual supplies up to ±22 V. High switching speed also makes the parts suitable for video 4. Single-supply operation. For applications where the analog signal switching. signal is unipolar, the ADG5408/ADG5409 can be operated Each switch conducts equally wel in both directions when on, from a single rail power supply up to 40 V. and each switch has an input signal range that extends to the 5. 3 V logic compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V. power supplies. In the off condition, signal levels up to the 6. No VL logic power supply required. supplies are blocked.
