The ADG774BRZ is a high-speed CMOS quad SPST analog switch that is part of the Interface - Analog Switches, Multiplexers, Demultiplexers product family. It is a highly robust device that operates on a standard single +3.3 V supply and is characterized for operation from -40 °C to 85 °C. The device’s low on-resistance, specified at 125 Ω (@ 3.3 V) and minimum zero-state power consumption make it suitable for use in a wide range of applications. This device is compliant to the RoHS Directive 2002/95/EC and has a Pb-free design.

The ADG774BRZ is a quad single-pole, single-throw (SPST) switch that is controlled independently through the four digital pins (T/R/EN). Its low on-resistance and low off-leakage current makes it suitable for power and signal routing in precision analog circuits. It can be used in battery-powered mobile communication systems as well as a variety of other portable applications. The switches also provide excellent linearity and fast switching speeds which make it suitable for more demanding applications such as high-speed video, waveform sample-and-hold and telecommunications.

The ADG774BRZ switches are divided into four independent sections, each with its own enable (EN) and transfer (T/R) pins. The EN pin, which is an active-LOW output enable pin, controls the output by enabling or disabling the corresponding switch section. When the EN pin is high, the switch sections will be disabled and the output will be tri-stated. When the EN pin is low, the switches will be enabled and the output will be connected to their respective inputs. The T/R pin is an active-HIGH pin that controls whether the switch section connects its input (when T is high) or its output (when R is high) to the switch output terminal.

The ADG774BRZ switches offer the benefit of both low on-resistance and low off-leakage current, making them ideal for use in portable and mobile applications. The device is capable of handling both high-speed digital and standard analog signals, as well as providing effective signal routing and level shifting solutions. Furthermore, due to its small size, the ADG774BRZ is suitable for use in space-constrained designs such as mobile phones and PDAs.

The ADG774BRZ is ideal for applications such as level shifting, signal routing, sample-and-hold circuits, and low frequency switching. It is well suited as a high-speed switch in a variety of applications including video, audio, telecom and instrumentation.
