Description

The STG1218 is a quad channel analog switch (SPDT), which is able to

accommodate with positive and negative voltages. Each channel has an independent

selection pin, and a common inhibit pin. Thanks to its large operating voltage range

and low Ron, this switch can fit many applications such as RRU (both LDMOS and

GaN solutions). It is also a good operational amplifier companion chip used with

a standard 3.3 V single supply operation for gain selection. In addition, it has the

versatility to be compatible with 3.3 V and 1.8 V logic standard thresholds.

Applications

• 5G telecom infrastructure

• Remote radio unit LDMOS and GaN

• Gain selection for instrumentation
