DG444CJ

Overview

The DG444CJ 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 parameters include a turn-on time of 250ns maximum, a turn-off time of 120ns maximum, and charge injection of 10pC maximum. It is housed in a 16-pin Plastic DIP package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

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

Applications

Sample-and-hold circuits
Test equipment
Heads-up displays
Guidance and control systems
Audio signal routing

Procurement Notes

Verify the specific suffix 'CJ' corresponds to the 16-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm RoHS compliance status as legacy parts may vary. Ensure the ordering code matches the manufacturer's current designation for this component variant.

Selection Notes

Select the DG444CJ when a normally closed SPST configuration is required. Compare against the DG445CJ if a normally open configuration is needed instead. Consider the DG444DJ variant if operation in industrial temperatures down to -40°C is necessary. Verify that the 85 ohm on-resistance meets the circuit requirements.

Part Context

The DG444CJ belongs to the DG444/DG445 family of improved analog switches. This series was redesigned to offer better performance than industry-standard predecessors, specifically regarding on-resistance matching and flatness. The C suffix denotes the commercial temperature grade, while J indicates the plastic DIP package style.
