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.","metaTitle":"MAX146ACAP+ 12-bit SAR ADC, 133k SPS, SPI, 20-SSOP","metaDescription":"Maxim MAX146ACAP+ 12-bit SAR ADC with 133k sampling rate, SPI interface, 4/8 input mux. 2.7V-3.6V supply.

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."},{"question":"Does MAX146ACAP+ require an external reference?","answer":"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.
