Analog To Digital Converters (ADC) Procurement Notes

The AK9232NK has been officially declared End-of-Life (EOL) by the manufacturer as of June 9, 2021. Current availability is limited to existing stock; no new production units are being manufactured. Designers should verify component authenticity and check expiration dates for moisture sensitivity level (MSL 2) compliance before integration into new hardware.

Analog To Digital Converters (ADC) Selection Notes

Select the AK9232NK when a dual-channel, high-speed 16-bit conversion capability is required within a low-voltage power budget. This component is suitable for designs needing differential inputs and internal clocking without external crystal dependencies. Ensure the PCB layout supports the 24-QFN package and adheres to the recommended decoupling capacitor placement shown in reference schematics.

Analog To Digital Converters (ADC) Part Context

The AK9232NK belongs to the AK923x family, which includes the AK9232, AK9233, and AK9234 models. These devices share similar architectural characteristics but differ in specific pin configurations or feature sets. The 'NK' suffix denotes the specific tape-and-reel packaging format and pin assignment variant used in this part number.

Analog To Digital Converters (ADC) Replacement Considerations

Due to the EOL status, direct replacements must be sourced from secondary markets or alternative manufacturers offering equivalent 16-bit dual-channel SAR ADCs. Verify that substitute components match the 24-QFN footprint and 1.7V-2V supply requirements.
