ADG526AKR

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG526AKR is a CMOS monolithic analog multiplexer featuring 16 single channels in a 28-lead SOIC package. It operates within a wide supply range of 10.8 V to 16.5 V for both single and dual configurations. Key electrical parameters include a maximum on-resistance (RON) of 450 Ω at 25°C, rising to 600 Ω across the extended temperature range of −40°C to +85°C. The device exhibits typical off-isolation of 68 dB, maximum leakage currents of 1 nA, and dynamic switching times with a maximum transition delay of 300 ns.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm package type and compliance status. The 'K' designation indicates the commercial temperature grade. Check for RoHS compliance markers if environmental regulations apply. Confirm availability through authorized distributors as manufacturing status may vary. Ensure the selected variant matches the required PCB footprint and thermal management needs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high channel count and latchable control. Compare RON specifications against signal integrity requirements. Consider the extended signal range capability when designing for varying supply voltages. Evaluate thermal dissipation limits relative to the operating environment. Verify digital input compatibility with the host controller logic levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ADG526A/ADG527A family of CMOS latched analog multiplexers manufactured by Analog Devices. The ADG526A variant specifically provides 16 single-ended channels, whereas the ADG527A offers dual 8-channel differential configurations. Both share similar architectural features and are designed as superior alternatives to legacy DG526 and DG527 devices.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public documentation identifies the DG526 and DG527 as legacy predecessors. When substituting, verify pinout compatibility and ensure the replacement meets the required supply voltage and leakage specifications. Confirm that the alternative device supports the necessary latch functionality and signal range.
