The MAX135 is a CMOS 15-bit, binary-output analog-to-digital converter (ADC). Multi-slope integration provides low-noise and high-resolution conversions in less time than standard integrating ADCs: The MAX135 is tested at 16 conversions per second, but operates at up to 6 times that rate. The MAX135 uses Super LSBs with data averaging to achieve 18-bit resolution.
Supply current is 125 A maximum during normal operation and only 10 A maximum in sleep mode. Low conversion noise allows tested operation at only 300mV full scale (15 V per LSB). A simple 8-bit parallel data bus and three control lines easily interface to all common microprocessors, and twos-complement output coding simplifies bipolar measurements.
High resolution and compact size make the MAX135 ideal for data loggers, numerical control systems, weight scales, data-acquisition systems, and panel meters. The MAX135 comes in 28-pin DIP and SO packages in both commercial and extended temperature grades.
