Product Description

The UM4157 is a low on resistance, low-power, Single Pole Double Throw (SPDT) analog switch. This product has been designed for switching audio signals in applications such as cell phones and portable media players. The ultra-low 0.8Ω impedance, sub μA current consumption, and 1.65V to 4.3V operating voltage range make this product ideal for battery-powered applications. The UM4157 also features bidirectional operation and break-before-make functionality. This device is fully specified for operation at 1.8V, 2.5V, and 3.3V.

Features

- Typical 0.8Ω On Resistance (R_ON) for 2.7V Supply

- 0.23Ω Typical R_ON Flatness for 2.7V Supply

- Broad V_CC Operating Range: 1.65V to 4.3V

- Low THD (0.02% Typical for 32Ω Load)

- Control Logic is 1.8V CMOS Logic Compatible

Applications

- Cellular Phone

- PDA

- Portable Media Player
