ADG528AKP

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG528AKP is a CMOS latched 8-channel analog multiplexer in a 20-lead PLCC package. It operates on single or dual supplies ranging from 10.8 V to 16.5 V, with a maximum supply rating of 44 V. The device features an analog signal range spanning from VSS to VDD. Key electrical parameters include a maximum on-resistance (RON) of 450 Ω and a typical leakage current of 20 pA. Switching times are specified at 300 ns maximum for transition, turn-on, and turn-off operations.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• On-chip latches facilitate direct microprocessor interfacing via TTL and 5 V CMOS logic-compatible inputs.
• Enhanced LC2MOS process provides an extended analog signal range from VSS to VDD.
• Break-before-make switching action protects input signals against momentary shorting during channel transitions.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring high precision and low leakage.
• Industrial control applications utilizing microprocessor-based address latching.
• Test and measurement equipment needing wide supply voltage tolerance.
• Signal routing in battery management and instrumentation circuits.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'KP' corresponds to the 20-lead Plastic Leaded Chip Carrier (PLCC) package option when sourcing. Confirm RoHS compliance status if required by assembly specifications, as indicated by the 'Z' suffix in related part numbers within the same family. Ensure the operating environment remains within the commercial temperature range of –40°C to +85°C for this specific variant.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG528AKP when eight single-ended channels require latched addressing without external latch components. Choose this device over non-latched alternatives for simplified digital interface designs. Consider the 20-lead PLCC package for board space constraints where surface-mount technology is preferred over DIP formats. Verify that the 450 Ω maximum on-resistance meets the signal integrity requirements of the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG528AKP belongs to the ADG528A/ADG529A series of CMOS monolithic analog multiplexers manufactured by Analog Devices. This family serves as a superior alternative to legacy DG528 and DG529 devices. The ADG528A specifically handles eight single-ended channels, while the ADG529A manages four differential channels. Both utilize enhanced LC2MOS processing for improved signal handling capabilities.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ADG528A is documented as a direct replacement for the DG528. Designers transitioning from DG528 should verify pin compatibility and ensure the new device's 450 Ω maximum on-resistance aligns with system performance thresholds. No other public substitutes are confirmed in the provided documentation.
