ADG451BNZ

The ADG451BNZ device is a quad single-pole, double-throw (SPDT) analog switch designed for use in a wide range of applications in the field of interface or where high speed signals need to be routed between components. It is commonly used for high-speed multiplexing and demultiplexing, in addition to providing switching of low-power audio signals.

The device is offered in an 8-lead SOIC package that is RoHS compliant. The device operates over a wide supply voltage range from 3V to 15V and has a maximum supply current of 35μA. It offers a low power shutdown feature to minimize power consumption while in off state, and the low on resistance of the switch together with the low off-leakage current and low control power consumption ensure a high-quality audio signal is maintained.

The ADG451BNZ is an ideal choice for multiplexing and demultiplexing while also providing a load damping and filtering mechanism. It is effective in multiplexing and demultiplexing and provides a low insertion loss. The insertion loss is typically 0.2dB for conductance and 0.4dB for resistance. It is designed to minimize power dissipation and noise.

The device can be programmed to a wide range of audio frequencies from 5Hz to 20MHz, thereby allowing a variety of applications. It is capable of handling high-speed switching signals of up to 1GHz. It has a low EMI/RFI susceptibility, low voltage/current levels, low capacitive loading and low power consumption for a wide range of applications.

In terms of the operating principle, the device uses a simple switched capacitor network. The device uses an internal voltage reference and series of controlled switches to provide the desired conductance value. These switches act as a linear resistor and the conductance is adjusted by switching between the two configurations internally, depending on the control voltage. This ensures the output voltage is unaffected by the switching speed and the capacitive loading of the switch.

The ADG451BNZ is a versatile device which has been designed for a wide range of applications in the field of interface or for multiplexing and demultiplexing. It offers high speed performance, low insertion loss, low power operation, and low EMI/RFI susceptibility, making it an ideal choice for applications involving multiplexers, demultiplexers, and switching of low-power audio signals.
