STG5123DTR Integrated Circuits (ICs)

The STG5123DTR part is an Analog Switches Multiplexers and Demultiplexers device. It is a monolithic first order high-speed, low-power analog switch, multiplexer and demultiplexer. It contains three separate switches, each switch connects two channels, and each switch is rated at 10mA max current. The device also contains a differential input, allowing the multiplexer or demultiplexer to be controlled by the differential voltage achieved by connecting the two inputs.

The main application for the STG5123DTR is for high speed switching in precision data acquisition systems. It is used in applications such as analog-to-digital conversions, servo control, and audio switching. It can also be used in applications requiring constant off-state impedance, such as in automatic gain control (AGC) systems. It can operate over the standard industrial temperature range, and is available in both through-hole and surface mount packages.

The working principle of the device is based on the N-channel MOSFETs used in its switching elements. When the control voltage applied to the differential input is increased, the internal MOSFETs turn on, and the channels connect. The output devices are designed to have minimal drain-source resistance, and the on-state resistance of the devices are tightly matched over the operating temperatures. This results in the device having low power dissipation and low distortion.

The STG5123DTR is an excellent choice for applications requiring high speed, low power, and tight off-state isolation. The device provides good performance over wide bandwidths, and is also capable of providing very tight crosstalk and isolation specifications. Due to its fast switching times and low power consumption, it is an ideal choice for applications requiring high speed, low distortion, and minimal power consumption.
