DG303AAK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG303AAK is a TTL-compatible CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features two independent single-pole double-throw (SPDT) channels housed in a 14-pin ceramic dual in-line package (CDIP). The device supports single or dual power supplies, with a minimum supply voltage of 10V and a maximum of 30V for single supply operation. Dual supply ranges from ±5V to ±18V. Key electrical parameters include a maximum on-resistance of 50 Ohms, a maximum power supply current of 500 uA, and a DC switch current of 30 mA. Switching times are specified at a maximum of 300 ns for turn-on and 250 ns for turn-off. The component operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'AAK' against official manufacturer documentation to confirm pinout compatibility and material specifications. Confirm availability status as this part number may be subject to limited production or obsolescence notices. Ensure that the CDIP-14 package dimensions match the target PCB footprint requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when TTL-compatible control signals are required alongside moderate on-resistance specifications. Consider the 50 Ohm on-resistance limit for signal integrity requirements. Verify that the operating temperature range of 0°C to +70°C meets the environmental constraints of the final assembly. Compare against the broader DG303 family for potential package or speed variations if stricter thermal or electrical limits are needed.
