The TS3A5018DRE4 is an integrated, dual-channel audio switching IC from Texas Instruments. It is part of TI’s portfolio of low-power analog switches, multiplexers, and demultiplexers. Its application field ranges from mobile phones and tablets to home audio systems, car audio systems, and portable multimedia players, as well as other consumer audio devices.The TS3A5018DRE4 is designed to enable seamless audio routing by connecting two independent audio sources with two independent audio sinks. It features two low-on-resistance, low-power switches with an on-resistance of less than 5.2Ω. The device is also capable of running on a supply voltage between 1.7V and 5.5V, making it well-suited for power-sensitive applications.In addition to its low-power performance and versatile supply voltage, the TS3A5018DRE4 also has a wide operating temperature range from -40 °C to +125 °C, making it suitable for a wide range of environments. The device is also compliant with the RoHS directive and is lead (Pb) free.The TS3A5018DRE4 consists of two separate channels and a control logic for each channel. Each channel consists of a single-pole, double-throw (SPDT) switch, a charge pump circuit, two low-voltage digital control inputs, an enable/disable control input, and an output enable/disable control input. The two control inputs allow the user to switch between two audio sources and two audio sinks. The enable/disable control input can be used to turn on or off the audio switching while the output enable/disable control input can be used to turn on or off the output signal.The charge pump circuit provides a negative voltage to the gate of the SPTD switch, enabling the switch to operate at low-power and low-voltage levels. The charge pump circuit can also be used to reduce the overall power consumption of the TS3A5018DRE4 by enabling the device to operate with a low quiescent current.The TS3A5018DRE4 is an ideal choice for audio routing applications that require high performance with low power consumption and wide temperature ranges. Its low on-resistance, low quiescent current, low-voltage operation, and wide temperature range make it suitable for a wide range of applications. Furthermore, its RoHS compliance and lead-free design make it an environmentally friendly and attractive choice for eco-sensitive applications.
