Advanced Linear Devices, Inc. CMOS Low Voltage, Low Charge Injection Quad SPST NC Analog Switches ALD4201SCL

The ALD4201SCL is a quad SPST CMOS analog switch designed for low voltage applications ranging from 3V to 12V, with a focus on low charge injection and low leakage currents. It features precision matching, fast switching times, low on-resistance of 90 to 135 ohms, and micropower consumption, making it suitable for precision applications such as charge amplifiers, sample and hold amplifiers, and data converter switches. This switch operates in a break-before-make configuration and is compatible with standard single or dual power supplies, allowing for operation down to +2V or -1V. It has a quiescent current in the nanoampere range and can interface directly with CMOS logic levels. The device is manufactured using Advanced Linear Devices' enhanced ACMOS silicon gate CMOS process, ensuring reliability and performance. The ALD4201SCL is ideal for battery-operated systems due to its low power dissipation of 0.1 mW and minimal charge injection of 1 pC. It also provides rail-to-rail signal range and features built-in dual supply level translation. The operating temperature range for the DC package is -55¬8C to +125¬8C, making it suitable for a variety of environmental conditions.
