The ISPGDX120A-7T176 is a dual-channel, non-latching, low on-resistance analog switch designed for a wide variety of applications. The output of the switch can be controlled by either digital or analog control. It has low total harmonic distortion (THD) and very low off-isolation, making it well suited for audio applications. This article will explore the various application fields and working principle of the ISPGDX120A-7T176.

Applications

The ISPGDX120A-7T176 is primarily used in audio applications where low distortion, low off-isolation, and fast switching is required. It can also be used in a wide range of applications such as portable audio players, test equipment, instrumentation, and broadcast systems. It is also suitable for video switching applications such as RGB video, broadband video, and S-video.

In addition, the ISPGDX120A-7T176 is also suitable for inductive load switching such as transducers, load cells, and of course, loudspeakers. The low series resistance and high current carrying capability makes it ideal for such applications.

The low source and sink current capability makes the ISPGDX120A-7T176 suitable for electro-mechanical switch replacement applications. This includes automation and controls products such as limit switches, photo-interrupters, and capacitive sensors.

Finally, the wide selection of on-resistance values and low leakage current also makes it suitable for switchable gain control and analog multiplexer applications.

Working Principle

The ISPGDX120A-7T176 is an analog switch with a 2-bit control. It is based on a dual-channel, non-latching, low on-resistance CMOS technology. It can be used with both analog and digital signals, with low total harmonic distortion (THD) and very low off-isolation.

The device consists of two input channels and an output channel, connected in series. For both channels, the on-resistance is typically lower than 0.25 ohm. When the switch is enabled, it connects the output to one of the two inputs. The control voltage must be applied to the control pin (scales from 0 to 5V, depending on logic voltage) to enable or disable the switch.

The switch is designed to produce minimal distortion(≤ 1%) for any type of input, including digital, analog, or high-frequency signals. The on-resistance is temperature compensated, providing consistent performance over temperature. The leaking current is also temperature compensated, making the ISPGDX120A-7T176 well suited for audio applications.

As the device is non-latching, it will always remain in the “on” state as long as the control voltage is present. When the control voltage is removed, the switch turns off and the output is disconnected from the inputs. The device has a low voltage drop when enabled, making it suitable for a wide range of applications.

In summary, the ISPGDX120A-7T176 is a low on-resistance, dual-channel, non-latching analog switch suitable for a wide variety of applications. It has low THD and very low off-isolation, making it well suited for audio and video switching applications. Its low series resistance, temperature compensated on-resistance, and low leakage current also makes it suitable for inductive load switching, automated controls, and analog multiplexing applications.
