The MAX132EWG+ is a ±18bit analogue to digital converter with serial interface in 24 pin WSOIC package. It is a CMOS, 18bit plus sign, serial output analogue to digital converter. Multi-slope integration provides high-resolution conversions in less time than standard integrating ADC, it allows operation up to 100 conversions per second. Low conversion noise provides operation with ±512mV full-scale input range (2μV/LSB). A simple 4-wire serial interface connects easily to all common microprocessors and twos-complement output coding simplifies bipolar measurements. Typical supply current is only 60μA and is reduced to 1μA in sleep mode. Four serially programmed digital outputs can be used to control an external multiplexer or programmable-gain amplifier. High resolution, compact size and low power make this device ideal for data loggers, weigh scales, data acquisition systems and panel meters.
