The FSA2268TUMX is a low-voltage dual Single-Pole Double-Throw (SPDT) analog switch designed for applications requiring minimal on-resistance and high performance. It features a typical on-resistance of 0.4Oc at a supply voltage of 3.0V, with a maximum on-resistance flatness of 0.25Oc. The device operates over a broad supply voltage range of 1.65V to 4.3V and is compatible with TTL-level control inputs. This switch is optimized for low quiescent current, making it suitable for battery-powered devices such as cell phones, PDAs, digital cameras, and notebooks. It also includes power-off protection on common ports and has a high ESD rating, with 16kV protection for power to ground and 13.5kV for I/O to ground. The FSA2268TUMX is packaged in a compact 10-lead Quad Ultrathin Molded Leadless Package (UMLP), measuring 1.4mm x 1.8mm, which is advantageous for space-constrained applications. Additionally, the inclusion of noise termination resistors enhances noise immunity, making it suitable for sensitive audio applications.
