DG303AC/D

Analog Switches, Multiplexers, Demultiplexers Overview

The DG303AC/D is a TTL-compatible CMOS analog switch featuring two independent single-pole double-throw (SPDT) channels. It operates within a supply voltage range of 10 V to 30 V for single supplies, or ±5 V to ±18 V for dual supplies. The device exhibits a maximum on-resistance of 50 Ohms and supports a continuous DC switch current of 30 mA. Switching performance includes a maximum turn-on time of 300 ns and a maximum turn-off time of 250 ns. Power consumption is limited to a maximum of 500 uA. The component is supplied as a bare die with an operating temperature range from 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific die revision and lot traceability requirements before procurement, as this component is sold as a bare die. Confirm that the manufacturing source is authorized by Analog Devices Inc. or Maxim Integrated to ensure compliance with original specifications. Check for any obsolescence notices or lifecycle status updates directly from the manufacturer's official documentation prior to ordering.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG303AC/D when a TTL-compatible interface is required alongside dual SPDT switching functionality. Ensure the application voltage does not exceed the 30 V single-supply or ±18 V dual-supply limits. Consider the bare die package format, which requires specialized mounting and handling procedures compared to standard integrated circuit packages. Verify that the 50 Ohm on-resistance meets the signal integrity requirements of the target circuit.
