ST’s analog switch portfolio ranges from SPDT switches to larger octal SPDT or quad DPDT switches, featuring low on-resistances, integrated 15 kV protection diodes and negative charge pump, and with a bandwidth meeting audio or USB requirements. They come in tiny packages, making them perfectly suited for portable applications, and can also address any application requiring high-performance switching.
Low RDS(on) analog switch single or dual
The ideal choice for wearable devices.
Switches are commonly used to multiplex or de-multiplex a great variety of signals. For instance, in portable applications, switches are used to route signals such as audio to speaker or to headphones. Nowadays, with the sensors and interface proliferation in new applications such as wearable, switches also become the ideal solution to route signals from / towards each other’s, and thus guaranteeing a simple efficient system implementation.
Low RDS(on) analog switches such as AS11P2TLR and AS21P2TLR are especially suited to low current / low voltage signals. Designed in silicon gate C2MOS technology to operate from 1.65 to 4.3 V, it offers very low ON resistance at VCC= 3.6 V (ex AS21P2TLR: RON< 0.5 Ω). They can easily sustain high bandwidth (450Mbps or more for AS21P2THBQ), and implement break-before-make delay time and ultra low power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them ESD and excess transient voltage immunity.
