ALD4211SCL

Analog Switches, Multiplexers, Demultiplexers Overview

The ALD4211SCL is a quad SPST normally open CMOS analog switch manufactured by Advanced Linear Devices Inc. It operates with single supplies from +3V to +12V or dual supplies from ±1.5V to ±6V. Key electrical parameters include an on-resistance of up to 135Ω at ±5V, charge injection of 0.2pC, and off leakage current of 100pA. Switching times are typically 130ns for both turn-on and turn-off delays. The device features rail-to-rail signal range capability and micropower consumption.
