General Description
The MAX135is a CMOS 15-bt binary-output analog-to-
digital converter (ADC), Multi-slope integrat‘on provides
Iow-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 125pA maximum during normal opera-
tion and only 10p/\ 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-corrplement output coding
simplifies bipolar measurements,
High resolution and compact size make the MAX135
KoCal'ordata loggers, rnumericalcontrjsystems, weigh
scales, data-acquisition systems, and panel meters The
MAX135 comes in 28-pin DIP and SO packages in both
commermaT and extended temperature grades,
