The MAX132CWG+T from Analog Devices (formerly Maxim Integrated) is an 18-bit multi-slope integrating ADC built for precision low-speed measurement. It samples at 100 SPS, offering high noise rejection at line frequencies — useful for weighing scales, industrial process monitors, and data-acquisition front-ends where resolution matters more than throughput. The part accepts a pseudo-differential input and communicates over SPI, keeping the digital interface lean. Supply rails are ±5 V for both analog and digital sides.
The built-in programmable gain amplifier (PGA) lets you scale small sensor signals before conversion. Reference is external — plan for a stable voltage reference to realize the full 18-bit dynamic range. Not suited for extended industrial or automotive environments.
Lifecycle status is Active per the manufacturer's record. ROHS3 compliant, so it passes current European environmental directives without exemption paperwork. For a BOM freeze on a new design, this part carries no near-term obsolescence risk.
