Product Details

The ADGM1144 is a wideband, single-pole, four-throw (SP4T) switch, fabricated using Analog Devices, Inc., microelectromechanical system (MEMS) switch technology. This technology enables a small form factor, wide RF bandwidth, highly linear, low insertion loss switch that is operational down to 0 Hz/DC, making it an ideal solution for a wide range of RF and precision equipment switching needs.

An integrated driver chip generates a high voltage to an electrostatically actuate switch that can be controlled by a parallel interface and a serial peripheral interface (SPI). All four switches are independently controllable.

The device is packaged in a 24-lead, 5 mm × 4 mm × 1.0 mm land grid array package (LGA).

The ADGM1144 has integrated 10 MΩ resistors required for floating node avoidance. The presence of these integrated 10 MΩ resistors saves board space and eliminates floating nodes on the switch. To ensure optimum operation of the ADGM1144, refer to the Critical Operational Requirements section of the data sheet.

Throughout this data sheet, multifunction pins, such as IN1/SDI, are referred to either by the entire pin name or by a single function of the pin, for example IN1, when only that function is relevant.
