High Voltage Latch-up Proof 8-Channel Multiplexer
An EN input on both devices enables or disables the device. When EN is disabled, all channels are switched off. The on-resistance profile is very flat over the full analog input range, which ensures good linearity and low distortion when switching audio signals. High switching speed also makes the parts suitable for video signal switching.
Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the power supplies. In the off condition, signal levels up to the supplies are blocked.
The ADG5408/ADG5409 do not have a VL pins; rather, the logic power supply is generated internally by an on-chip voltage generator
- Trench isolation guards against latch-up. A dielectric trench separates the P and N channel transistors thereby preventing latch-up even under severe overvoltage conditions.
- Low RON.
- Dual-supply operation. For applications where the analog signal is bipolar, the ADG5408/ADG5409 can be operated from dual supplies up to ±22 V.
- Single-supply operation. For applications where the analog signal is bipolar, the ADG5408/ADG5409 can be operated from a single-rail power supply up to 40V.
- 3 V logic-compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V.
- No VL logic power supply required.
- Relay replacement
- Automatic test equipment
- Data acquisition
- Audio and video switching
- Communication systems
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
A 16-lead TSSOP device can be clamped or soldered to the center of the evaluation board. Each pin of the device has a corresponding link from K1 to K16 that can be set to either VDD or GND. A wire screw terminal supplies VDD and GND. SMB connectors on the board allow additional external signals to be supplied to the device. In addition, there is space available at the top of the board for prototyping.
Full specifications of the device under test (DUT) are available in the corresponding product data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
