DIO1568 Dual Sim Card Analog Switch Description
The DIO1568 Evaluation Board (EVB) lets you quickly evaluate and prototype with the DIO1568 low-power, dual-SIM analog switch. The DIO1568 is a quad SPDT analog switch optimized for dual-SIM card multiplexing, operating from a single 1.65 V to 5.5 V supply. It offers ultra-low on-resistance (0.85 Ω on the SIM path) and fast, break-before-make switching thanks to sub-micron CMOS fabrication. The device also maintains very low quiescent current even when control voltage is below VCC, enabling direct interfacing with baseband processor GPIOs in mobile handsets. Two compact QFN package options are available: QFN1.8×2.6-16 and QFN3×3-16.
