ADG509AKR

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG509AKR is a CMOS monolithic analog multiplexer featuring two independent 4:1 channels. It operates within a supply voltage range of 10.8 V to 16.5 V for both single and dual configurations. The device supports an analog signal range from VSS to VDD, with a maximum rating of 44 V between supplies. Key electrical parameters include a maximum on-resistance (RON) of 280 Ω at +25°C and 400 Ω across the commercial temperature range. Leakage currents are typically 20 pA, with a maximum of 50 nA. Switching times are guaranteed at 300 ns transition and 400 ns enable delay in the commercial grade.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix 'KR' corresponds to the 16-lead Standard Small Outline Package (SOIC) as specified in the Analog Devices ordering guide. Confirm RoHS compliance status if required by assembly specifications, noting that 'Z' suffixes indicate RoHS compliant parts while standard suffixes may differ. Ensure the selected variant matches the required operating temperature range of −40°C to +85°C for commercial applications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the ADG509AKR when a dual 4:1 differential or single-ended multiplexer configuration is required. This component is suitable for designs needing break-before-make switching to protect against signal shorting. Compare on-resistance and leakage specifications against system requirements, particularly for precision applications where low charge injection and minimal off-state leakage are critical performance factors.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG509AKR belongs to the ADG508A/ADG509A series of CMOS analog multiplexers manufactured by Analog Devices. This family provides robust switching capabilities with wide supply tolerance. The ADG509A specifically offers dual 4:1 functionality, contrasting with the ADG508A's single 8:1 configuration. Both devices share similar electrical characteristics and package options, designed for reliable operation in industrial and commercial environments.
