Product details

12-bit SAR ADC with mux — what it does and where it fits

The Maxim Integrated MAX146ACAP+ is a 12-bit successive-approximation-register (SAR) ADC that samples at 133k samples per second. It packs an input multiplexer (4 or 8 channels), a sample-and-hold, and the ADC core into a single 20-SSOP package. The SPI data interface keeps the digital side simple — three or four wires to the host controller. Typical applications include industrial sensor front-ends, battery-monitoring systems, and data-acquisition modules where 12-bit resolution at moderate speed is the sweet spot between cost and performance.

Lifecycle and sourcing posture

The MAX146ACAP+ carries an active lifecycle status with ROHS3 compliance. For a BOM line that needs a 12-bit SAR ADC in a 20-SSOP, this part is a current-production choice — no need to qualify a replacement or stockpile for an EOL event.

Frequently asked questions

What is the maximum sampling rate of MAX146ACAP+?

The MAX146ACAP+ samples at 133k samples per second. That is the throughput rate for the SAR conversion; the SPI bus must be clocked fast enough to read the 12-bit result before the next conversion completes.

Does MAX146ACAP+ require an external reference?

No, it has an internal reference option. You can also supply an external reference if the application needs tighter accuracy or lower drift than the internal reference provides. The choice is per-design.
