DG405C/D

Overview

The DG405C/D is a dual, high-speed analog switch fabricated using a 44V silicon-gate process. It features two independent double-pole/single-throw (DPST) switches with TTL/CMOS-compatible logic inputs. The device operates from single +10V to +30V supplies or bipolar ±4.5V to ±20V supplies. Key electrical parameters include a maximum on-resistance of 45Ω and a typical value of 20Ω. On-resistance matching between channels is guaranteed at 2Ω max, while flatness over the signal range is 3Ω max. Switching times are 150ns for turn-on and 100ns for turn-off. Charge injection is limited to 15pC max, and off-leakage current is less than 5nA at +85°C. Power consumption is 35µW max.

Feature Summary

Dual DPST configuration with low on-resistance and guaranteed channel matching
TTL and CMOS logic compatibility across wide supply voltage ranges
Low charge injection and improved off-leakage characteristics over temperature

Applications

Sample-and-Hold Circuits
Test Equipment
Guidance and Control Systems
Heads-Up Displays
Communications Systems
PBX, PABX
Battery-Operated Systems
Audio Signal Routing
Military Radios

Procurement Notes

Verify the specific suffix 'C' or 'D' against the required operating temperature range before ordering. The 'C' variant supports 0°C to +70°C, while the 'D' variant covers -40°C to +85°C. Confirm package availability as dice specifications require direct factory contact. Ensure logic supply sequencing aligns with absolute maximum ratings to prevent damage.

Selection Notes

Select the DG405C/D when dual independent switching paths are required in a compact form factor. The device is suitable for applications demanding rail-to-rail signal handling and low power consumption. Consider the on-resistance match specification for precision signal routing tasks. Verify that the bipolar or single-supply voltage requirements fall within the specified operational limits for the chosen temperature grade.

Part Context

The DG405C/D belongs to the redesigned DG401/DG403/DG405 family of improved dual high-speed analog switches. This series offers enhanced performance over previous generations, including lower on-resistance and better leakage characteristics. The component is manufactured by Analog Devices Inc./Maxim Integrated using a robust silicon-gate process designed for reliability in various industrial and communication environments.
