http://www.union-ic.com Rev.01 Aug.2009 1 / 1 0 UM4157 0.8Ω Low-Voltage SPDT Analog Switch UM4157 SOT363 General Description The UM4157 is a low on resistance, low-power, Single Pole Double Throw (SPDT) analog switch. This product has been designed for switching audi o signals in applications such as cell phones and portable media players. The ultra-low 0.8 Ω impedance, sub μA current consumption, and 1.65V to 4.3V operating voltage range make this product ideal fo r battery-powered applications. The UM4157 also features bidirectional operation a nd break-before-make functionality. This device is fully specified for operation at 1.8V, 2.5V, and 3.3V. Applications Features z Cellular Phone z PDA z Portable Media Player z Typical 0.8Ω On Resistance (RON) for 2.7V Supply z 0.23Ω typical RON Flatness for 2.7V Supply z Broad VCC Operating Range: 1.65V to 4.3V z Low THD (0.02% Typical for 32Ω Load) z Control Logic is 1.8V CMOS Logic Compatible P i n C o n f i g u r a t i o n s T o p V i e w
