DG528AK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG528AK is an 8-channel multiplexer switch IC from the DG528 series, manufactured by Analog Devices Inc./Maxim Integrated. It features a 1 x 8:1 configuration housed in a 16-pin CDIP package with through-hole mounting. The device operates on single supplies from 5 V to 30 V or dual supplies of ±4.5 V to ±20 V. Key electrical parameters include a maximum on-resistance of 450 Ohms, a channel-to-channel matching of 27 Ohms, and switching times of 1.5 µs for both turn-on and turn-off. It supports power dissipation up to 889 mW and functions within a commercial temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix AK against official datasheets to confirm package type and temperature grade. Confirm availability status as legacy components may have limited production runs. Ensure compatibility with existing board layouts for the CDIP-16 footprint during sourcing.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel analog switch with low on-resistance and latchable control is required. Compare against the DG528CJ+ for industrial temperature ranges if operation below 0°C is needed. Verify that the 450 Ohm on-resistance meets the signal integrity requirements of the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG528AK belongs to the DG528 family of latchable multiplexers designed for general-purpose analog switching. This series integrates eight channels into a single package, offering a compact solution for signal routing tasks. The device utilizes CMOS technology to provide high isolation and low power consumption compared to mechanical relays.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG528CJ+ is a verified substitute within the same family, offering identical functional specifications. Verify that the CJ+ variant meets the required operating temperature range, as it typically covers 0°C to +70°C. Check pinout compatibility to ensure direct replacement without PCB redesign.
