IEMIIM
115-13111L ADC with Parallel [Interface
General Description
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
timesthat rate. The MAX135 uses Super LSBs with data
averaging to achieve 18-bit resolution.
Supply current is 125pA maximum during normal opera-
tion and only 10pA maximum in sleep mode. Low con-
version noise allows tested operation at only 300mV full
scale (15W 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, weigh
scales, data-acquisition systems, and panel meters. The
MAX135 comes in 28-pin DIP and SO packages in both
commercial and extended temperature grades.
