ADG212AKP-REEL

Analog Switches, Multiplexers, Demultiplexers Overview

The ADG212AKP-REEL is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc. It utilizes LC2MOS technology to support an analog signal range of ±15 V and a maximum supply voltage of 44 V. The device features a maximum on-resistance of 115 Ω with channel-to-channel matching of 5.75 Ω. Key electrical parameters include a typical leakage current of 0.5 nA, charge injection of 20 pC, and switching times of 600 ns (Ton) and 450 ns (Toff). It operates within a temperature range of -40°C to +85°C and is housed in a 20-lead PLCC package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix REEL indicates tape and reel packaging for the ADG212AKP variant. Confirm availability status as distribution data may vary. Ensure compatibility with existing 20-PLCC footprints. Check for RoHS compliance documentation corresponding to the manufacturing date code. Validate that the ordering part number matches the required package style before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high voltage signal handling up to ±15 V is required alongside low leakage characteristics. The 115 Ω on-resistance suits applications where precise resistance matching is less critical than voltage range. Compare against ADG211A for normally closed configurations or ADG1612 for lower resistance needs. Ensure the 20-PLCC package fits the board layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ADG212AKP belongs to the ADG211A/ADG212A family of monolithic CMOS switches. These devices are pin-compatible with legacy DG211/DG212 parts, facilitating direct upgrades. The ADG212 variant specifically offers four SPST switches, whereas the ADG211 offers different configurations. This family emphasizes robustness in industrial environments through extended temperature ranges.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the ADG211AKP for complementary switching logic. Legacy equivalents such as the DG212 may function but lack modern LC2MOS performance metrics. Verify package integrity when substituting PLCC variants. Cross-reference datasheets for on-resistance and leakage differences.
