DG403C/D

Overview

The DG403C/D is a dual, high-speed analog switch featuring two single-pole/double-throw (SPDT) channels. It operates from a single +10V to +30V supply or bipolar supplies of ±4.5V to ±20V. The device guarantees low on-resistance matching between switches (2 Ω max) and on-resistance flatness over the signal range (3 Ω max). Typical on-resistance is 20 Ω with a maximum of 45 Ω for the C/D variants. Switching times are 150 ns max for turn-on and 100 ns max for turn-off. Power consumption is limited to 35 µW max. The component supports rail-to-rail signal handling and maintains TTL/CMOS logic compatibility.

Feature Summary

Guaranteed low on-resistance matching between channels and flatness over the signal range
Low charge injection and improved off-leakage current performance over temperature
Break-before-make switching action for SPDT configurations
TTL and CMOS logic compatible operation

Applications

Sample-and-Hold Circuits
Test Equipment
Guidance and Control Systems
Communications Systems
Audio Signal Routing

Procurement Notes

Verify the specific suffix against official documentation to confirm the operating temperature range and package type. The 'C' designation indicates a commercial range of 0°C to +70°C, while 'D' denotes an extended range of -40°C to +85°C. Ensure the selected variant matches the thermal requirements of the target application environment before finalizing procurement.

Selection Notes

Select this component when precise analog signal routing with minimal distortion is required. The guaranteed on-resistance matching ensures balanced signal paths in differential applications. Verify that the supply voltage range aligns with the system's power architecture, as the device supports both single and bipolar supply configurations up to 44V total rating.

Part Context

The DG403C/D belongs to the redesigned DG401/DG403/DG405 series of monolithic CMOS analog switches. This family improves upon previous industry-standard versions by offering enhanced electrical characteristics, including lower leakage and better resistance matching. The DG403 specifically provides dual SPDT functionality within a compact 16-pin package format.
