AiT Semiconductor Inc. www.ait-ic.com A4722 QUAD SPDT ANALOG SWITCH 0.5 Ω, LOW VOL TAGE REV2.0 - SEP 2009 RELEASED, MAY 2017 UPDATED - - 1 - DESCRIPTION FEATURES The A4722 is a quad, low on- resistance, low voltage, bidirectional, single- pole/double-throw (SPDT) CMOS analog switch that is designed to operate from a single +1.8V to +4.2V power supply. Targeted applications include battery powered equipment that benefit from low RON (0.5Ω) and fast switching speeds (tON = 52 ns, tOFF = 25 ns). The A4722 consists of four SPDT switches. It is configured as a dual double- pole/double-throw (DPDT) device with two logic control inputs that control two SPDT switches each. The configuration can be used as a dual differential 2 -to-1 multiplexer/demultiplexer. The A4722 is available in QFN16 package.
