ADG511BRZ – ANALOG DEVICES

Overview

The Analog Devices ADG511BRZ is a high-performance, quad, single-pole, normally closed (SPST-NC) analog switch designed for precision signal routing. Its critical operational characteristic is the low on-resistance of 30 Ohms (typ), enabling minimal signal attenuation. A key design consideration when implementing this device is managing the trade-off between its robust ±4.5V to ±5.5V dual supply capability and the potential for increased leakage current at higher voltages, which can impact low-power applications. This IC excels in applications demanding reliable switching of analog signals with minimal distortion.
