GT4157
The GT4157 is a single-pole double-throw (SPDT) analog switch that is designed to operate from1.65V to 5.5V. The GT4157 device can handle both analog and digital signals. It features high-bandwidth(300 MHz) and low onresistance (2.2 Ω @ 4.5 V). Applications: signal gating, chopping, modulation or demodulation(modem), and signal multiplexing for analogto-digital and digital-to-analog conversion systems.
