The AD75019 is a 16×16 array that contains 256 analog switches. It has a wide signal range and can be powered by supply rails of 24V or ±12V. The switches have a low on-resistance of 200Ω. It supports TTL/CMOS/microprocessor control lines and has a serial input and serial output interface for cascading multiple channels. It has low power consumption with a quiescent power of 2mW. The product is compact in size and comes in a 44-lead PLCC package.
The AD75019 is a 16x16 crosspoint switch array containing 256 analog switches. It allows any of the X or Y pins to serve as an input or output, and any or all of the X terminals can be programmed to connect to any or all of the Y terminals. The device is fabricated in Analog Devices' BiMOS II process, offering low distortion and ESD protection.
Data is loaded serially via the SIN input and clocked into an on-board 256-bit shift register via SCLK. When all switch settings have been programmed, data is transferred into a set of 256 latches via PCLK. The switches can accommodate signals with amplitudes up to the supply rails and have a typical on-resistance of 150 Ω.
