Overview
The DG403CY+T is a dual, high-speed analog switch manufactured by Analog Devices under the Maxim Integrated brand. It features two single-pole double-throw (SPDT) channels housed in an 8-pin SOIC-Narrow surface-mount package. The device operates with a single supply voltage ranging from 10 V to 30 V or dual supplies between ±4.5 V and ±20 V. Key electrical specifications include a maximum on-resistance of 45 Ohms, a maximum turn-on time of 150 ns, and a maximum turn-off time of 100 ns. It supports a continuous DC switch current of 20 mA and draws a maximum supply current of 1 uA. The component functions within a temperature range of -40°C to +85°C.
Feature Summary
- Dual SPDT configuration for flexible signal routing
- High-speed switching performance suitable for dynamic applications
- Low power consumption with minimal supply current draw
- TTL/CMOS compatible logic control inputs
Applications
- Data acquisition systems requiring signal multiplexing
- Audio signal path switching and routing
- Instrumentation front-end signal conditioning
- Communication equipment signal selection
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this part number. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides valid traceability data for quality assurance purposes. Cross-reference the full part number against the latest datasheet to confirm pinout and electrical characteristics match design requirements.
Selection Notes
Select this component when dual independent SPDT switching is required in a compact surface-mount footprint. The 45 Ohm on-resistance and sub-microampere supply current make it suitable for low-power, general-purpose analog signal routing. Compare against the DG403DY variant if through-hole mounting is preferred instead of surface-mount technology. Ensure the operating voltage range aligns with the system's single or dual supply rails.
Part Context
The DG403 series represents improved CMOS analog switches designed for high-speed applications. This specific model belongs to the DG403 family, which offers enhanced performance over earlier generations like the DG303. The device integrates two SPDT switches on a single chip, providing a compact solution for signal management in mixed-signal systems.
Replacement Considerations
The DG403DY+ serves as a direct functional equivalent in a different SOIC-16 package. For through-hole requirements, the DG403DJ+ offers identical electrical specifications in a DIP-16 package. Verify pin compatibility and thermal characteristics when substituting these variants.
