Interface - Analog Switches - Special Purpose

The OPA875IDGKT is a high-performance, fast-acting switch, manufactured by Texas Instruments, specifically designed for the use in video, audio, telecommunications, and instrumentation circuits. It is a single CMOS analog switch with a “true” single-pole, double-throw (SPDT) functionality. It can be used to switch between two high-impedance sources such as capacitors and resistors while maintaining the full signal integrity of any analog signal being sent through it.

OPA875IDGKT may be used to switch between a variety of signals, including both AC and DC signals. The switch is designed to operate between a voltage range of 3.0V and 10V. It has a robust supply range for both low-noise and high-speed operations, making it suitable for operation in a variety of temperature ranges, from -40°C up to 125°C. Thanks to its high switching speed and low input capacitance of 0.45pF, it is ideal for switching between high-frequency signals such as audio, video, RF, and telecommunications signals.

The OPA875IDGKT comes with a variety of features, most notable of which is the ability to hold a signal switch position even during power-down and restore it to the proper state only when power is restored. This is possible thanks to its special low-leakage design and its two-level protection against latch-up. The device also come with an on-chip ESD protection and programmable charge pump, which helps to reduce the need for external components.

The device is also well suited for multiplexer applications thanks to its high-impedance outputs, fast settling times, and low distortion. It also has a low-pass filter on the input for better performance in high-frequency applications and can operate up to 1.5GHz. Additionally, its small package footprint (SOT-23-5) allows it to be conveniently integrated into densely populated boards.

The OPA875IDGKT is ideally suited for use in applications where high-isolation and signal integrity are essential, such as video, audio, and telecommunication systems. Its low-noise and high-bandwidth properties make it a great choice for signal switching and multiplexing applications in these environments. The device provides reliable and error-free signal switching between two input sources while ensuring that no distortion or signal degradation occurs. This makes it a great choice for high-performance analog switching solutions.
