ADG528AKPZ-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG528AKPZ-REEL is a CMOS monolithic analog multiplexer featuring eight channels and on-chip latches for microprocessor interfacing. It switches one of eight inputs to a common output based on three binary addresses and an enable input, utilizing TTL and 5 V CMOS logic-compatible digital inputs. The device operates within a wide supply range of 10.8 V to 16.5 V for both single and dual supplies. Key electrical parameters include a maximum on-resistance (RON) of 700 Ω under single-supply conditions and 600 Ω under dual-supply conditions at +85°C. Leakage currents are typically 20 pA, with power dissipation capped at 28 mW. The component supports break-before-make switching and functions in the –40°C to +85°C temperature range.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• On-chip latches facilitate direct microprocessor interfacing by latching address and enable data on the rising edge of the write signal.
• Enhanced LC2MOS processing provides an extended analog signal range from VSS to VDD and high breakdown voltage capability.
• Break-before-make switching action guarantees that input signals are protected against momentary shorting during channel transitions.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring multiplexed analog inputs
• Industrial process control instrumentation
• Medical equipment signal conditioning

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm package type and reel configuration. The REEL suffix indicates tape-and-reel packaging suitable for automated assembly processes. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor specifications before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring eight-channel multiplexing with integrated address latching. Ensure the design accommodates the specified 10.8 V to 16.5 V supply range. Verify that the 20-Lead PLCC package dimensions fit the PCB layout constraints. Consider thermal management requirements if operating near the maximum power dissipation limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG528A series of CMOS latched analog multiplexers manufactured by Analog Devices. It serves as a superior alternative to legacy parts like the DG528. The ADG529A variant, which offers four dual channels, is noted as obsolete in current documentation. The ADG528A family is designed for applications demanding low leakage and reliable switching performance.
