ADG528FBP

The ADG528FBP is a CMOS analog multiplexer manufactured by Analog Devices, featuring eight single channels with fault protection. This device is designed to protect both the device and the signal source in the event of overvoltage or power loss, withstanding continuous overvoltage inputs from -40 V to +55 V. During fault conditions, the input or output appears as an open circuit, allowing only a few nanoamperes of leakage current to flow.

Key electrical specifications include a typical on-resistance of 300 Ohms and a maximum of 350 Ohms. Switching times are fast, with both turn-on (tON) and turn-off (tOFF) times at a maximum of 250 ns. The device operates with supply voltages ranging from 10.8 V to 16.5 V for single supply and ±10.8 V to ±16.5 V for dual supply. It offers low power dissipation, with a maximum of 3.3 mW.

The ADG528FBP is constructed with a break-before-make mechanism to protect input signals from momentary shorting. It is available in a 20-PLCC (9x9) surface mount package. The operating temperature range is -40°C to 85°C (TA). This multiplexer is suitable for existing multiplexer applications, both fault-protected and non-fault-protected, as well as new designs requiring multiplexer functions.
