Analog switches can be used to route analog and digital signals with low loss. The TS3L301DGGG4 is a good example especially designed with the engineer in mind. This article will give an overview of the characteristics, application fields and working principles of the TS3L301DGGG4.

Overview

The TS3L301DGGG4 is an analog switch integrated circuit (IC) for switching analog signals. It is a low-voltage low-power CMOS device available in an 8-pin TSOP package. The device features a voltage rating of 7V and an OFF state leakage current of 5nA. The ON resistance (RON) of the device is 12Ω max and it can handle an on-state current of up to 20mA. An operating temperature range of -55 °C to 125 °C makes the device suitable for a wide range of applications.

Application Fields

The TS3L301DGGG4 analog switch is ideal for use in a variety of applications including automotive, industrial and consumer. Specifically, it is well-suited for switching signals and relays in automotive infotainment, industrial process control and consumer audio/video equipment.

The device’s small package size, low power consumption and wide temperature range make it an attractive choice for space-constrained and energy-efficient designs. Its low-loss switching performance and low OFF state leakage current make it suitable for use in high-bandwidth applications.

Working Principle

The TS3L301DGGG4 device features two single-pole single-throw (SPST) analog switches with the same control voltage. The ENABLE and DISABLE pins are used to control the switch state and the SEL pin is used to determine between the two switch states.

When the ENABLE pin is in logic high, it activates the switch and the SEL pin decides which of the two switch states will be activated. If SEL is logic high, then Switch A is activated; if SEL is logic low, then Switch B is activated. When the DISABLE pin is in logic high, both switches are OFF regardless of the SEL pin.

The TS3L301DGGG4 analog switch can also be used in single pole double throw (SPDT) application. In this case, both ENABLE and DISABLE pins are used to control the switches. When both pins are in logic high, Switch A is activated; when both pins are in logic low, Switch B is activated; and when the two pins do not match (ENABLE is logic high and DISABLE is logic low or vice versa), both switches are OFF.

Conclusion

The TS3L301DGGG4 analog switch is an ideal choice for space-constrained and energy-efficient designs. Its low-loss switching performance, low OFF state leakage current and wide temperature range make it suitable for a wide range of applications. Its features enable it to be used for switching signals and relays in automotive infotainment, industrial process control and consumer audio/video equipment.
