ADG849YKSZ-REEL7: Fast Switching for Precision Applications
Overview
The ADG849YKSZ-REEL7 is a high-performance single-pole double-throw (SPDT) analog switch from Analog Devices (ADI). Manufactured using advanced CMOS technology, it features ultra-low on-resistance (Ron), extremely low power consumption, and fast switching time. This device is particularly suitable for applications such as high-precision signal switching, measurement instruments, portable devices, and communication systems.
The ADG849YKSZ offers single-supply operation (1.8V ~ 5.5V), with an on-resistance of only 0.8Ω (typical) and a switching time of only 20ns, maintaining excellent linearity and low distortion performance in high-speed signal paths. The device is housed in a miniature SC70-6 (SOT-363) package, making it ideal for high-density, low-power system designs.
