The device switches one of eight inputs to a common output as determined by 3-bit binary address lines A0, A1, and A2. An EN (enable) input activates or disables the device, with all channels off when EN is low. The on-resistance is 40 Ohm typical and 100 Ohm maximum over the full signal range and temperature. The LC2MOS process provides low power dissipation (<75uA supply current), high switching speed, and low on-resistance. Each channel conducts equally well in both directions, and the input signal range extends to the supply rails (VSS to VDD). All channels exhibit break-before-make switching action, preventing momentary shorting when switching channels. The device is a direct replacement for the DG408 with improved performance. The RZ suffix denotes the 16-pin SOIC package.","working_principle":"The ADG408BRZ operates as an 8-channel analog multiplexer using CMOS transmission gates. (1) Channel Selection: The 3-bit address (A2, A1, A0) is decoded by an internal logic circuit that activates one of eight transmission gates. Each transmission gate consists of parallel N-channel and P-channel MOSFETs, providing bidirectional signal conduction with low and relatively flat on-resistance across the signal range. (2) Break-Before-Make: When the address changes, the currently selected channel is disconnected before the new channel is connected. This prevents momentary shorting between two inputs, which could damage signal sources or corrupt data. (3) Enable: The EN input controls all channels simultaneously. When EN is low, all transmission gates are off, presenting a high impedance at the output. When EN is high, the addressed channel connects to the output. (4) LC2MOS Process: The enhanced LC2MOS (Low Capacitance CMOS) process minimizes parasitic capacitances, enabling fast switching and low charge injection. The low charge injection reduces output transients when switching between channels.","pin_description":"
