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. Operating temperature is commercial grade, 0 °C to 70 °C. Not suited for extended industrial or automotive environments.
Lifecycle status is Active per the manufacturer's record. No end-of-life notice, no last-time-buy window. 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.
