DG303ACWE+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG303ACWE+ is a TTL-compatible CMOS analog switch featuring two single-pole double-throw (SPDT) channels in a 16-lead wide SOIC package. It operates with dual supplies from ±5V to ±18V or a single supply of +10V to +30V. The device exhibits an on-resistance of less than 50Ω, which remains constant over the analog signal range. Key electrical parameters include a maximum turn-on time of 300ns and a turn-off time of 250ns at +25°C. Charge injection is typically 12pC, while off-isolation reaches 62dB. The component supports continuous currents up to 30mA and functions within a commercial temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'ACWE+' against the manufacturer's current datasheet revision to confirm pinout compatibility and package dimensions. Confirm that the commercial temperature grade meets system requirements. Check for RoHS compliance status as manufacturing processes may evolve. Ensure the 16-lead wide SOIC footprint matches the PCB layout constraints before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPDT switching functionality is required with minimal power consumption. The low on-resistance makes it suitable for precision signal routing. Verify that the input logic levels align with the system's digital voltage standards. Consider the thermal dissipation capabilities if operating near the upper limits of the specified temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG300A–DG303A family of analog switches manufactured by Analog Devices / Maxim Integrated. These devices are electrically and pin-compatible with original manufacturer equivalents. The family includes variations such as DG300, DG301, and DG302, differing primarily in channel configuration and pole count. The DG303 variant specifically provides two SPDT switches.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG303ACK serves as a direct pin-compatible alternative in a ceramic DIP package. Other members of the DG300A-DG303A family share electrical characteristics but differ in physical form factors.
