ADG426:  LC2MOS, ±15 V ,16 Channel High Performance Analog Multiplexer

製品概要

The ADG426 is a monolithic CMOS analog multiplexer. The ADG426 switches one of sixteen inputs to a common output as determined by the 4-bit binary address lines A0, A1, A2 and A3. The ADG426 has on-chip address and control latches that facilitate microprocessor interfacing. An EN input on all devices is used to enable or disable the device. When disabled, all channels are switched OFF.

The ADG426 is designed on an enhanced LC2MOS process that provides low power dissipation yet gives high switching speed and low on resistance. These features make the parts suitable for high speed data acquisition systems and audio signal switching. Low power dissipation makes the parts suitable for battery powered systems.
