DG441C/D

Overview

The DG441C/D is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four normally closed switches with an on-resistance of 85 ohms maximum and an on-resistance match between channels of 4 ohms maximum. The device operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. Key electrical characteristics include a turn-on time of less than 250ns, a turn-off time of less than 170ns, charge injection of 10pC maximum, and off-leakage current of less than 5nA at +85°C. The component is available in dice form for the C/D suffix.

Feature Summary

Quad SPST configuration with four normally closed switches
Low on-resistance matching between channels
Guaranteed on-resistance flatness over the signal range
TTL/CMOS logic compatible

Applications

Sample-and-Hold Circuits
Communication Systems
Test Equipment
Battery-Operated Systems
Audio-Signal Routing

Procurement Notes

Verify the specific package type required for the application, as the DG441C/D designation refers to die specifications rather than a standard packaged component. Contact the manufacturer directly for dice availability and processing details. Ensure that the ordering suffix matches the intended temperature range and packaging format to avoid compatibility issues during integration.

Selection Notes

Select this component when a quad SPST switch with normally closed contacts is required. The DG441C/D variant specifically denotes the die version, suitable for custom packaging or specialized assembly processes. Consider the operating temperature range and supply voltage requirements to ensure compatibility with the system design constraints.

Part Context

The DG441C/D belongs to the DG441/DG442 family of improved, quad, SPST analog switches. This series is fabricated using a 44V silicon-gate process, offering enhanced performance over previous generations. The DG441 variant specifically provides normally closed switches, while the DG442 offers normally open configurations. Both share similar electrical characteristics and pinouts.
