Maxim MAX132 18-Bit ADC Datasheet
The MAX132 is a CMOS, 18‑bit plus‑sign, serial‑output analog‑to‑digital converter offering high‑resolution conversions at up to 100 conversions per second. It features a simple 4‑wire serial interface, low supply current (60 µA normal, 1 µA sleep) and four programmable digital outputs for external control.
The device is available in 24‑pin narrow DIP and wide SO packages, operates over a wide temperature range, and is suited for data loggers, weigh scales, and panel meters. Detailed electrical characteristics, pin descriptions, and design guidelines are provided for integrating the ADC into various applications.
