ADG751 is a low voltage SPST (single pole, single throw) switch that has excellent off isolation and wide bandwidth. It can be used for audio and video switching, RF switching, network applications, battery powered systems, communication systems, relay replacement and sample-and-hold systems.
The ADG751 is a low‑voltage SPST (single‑pole, single‑throw) CMOS switch designed for audio, video, RF, networking, battery‑powered and communication applications. It uses a T‑switch configuration to provide excellent off‑isolation while maintaining a wide signal bandwidth.
Typical specifications include off‑isolation of –75 dB at 100 MHz, a –3 dB bandwidth of 300 MHz, on‑resistance as low as 15 Ω (B‑grade), and power consumption below 0.01 pW. The device is supplied in 6‑lead SOT‑23 (RT‑6) and 8‑lead SOIC (RM‑8) packages, with recommended PCB layout and decoupling practices for high‑frequency performance.
