MAX135CWI+ by Analog Devices

±15-Bit, Low-Power ADC with Parallel Interface


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 125µA maximum during normal operation and only 10µA maximum in sleep mode. Low conversion noise allows tested operation at only 300mV full scale (15µV 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.
