Maxim MX7581JN+

Overview

The MAX161 and MX7581JN are CMOS single-chip 8-bit, 8-channel data acquisition systems (DAS). Each chip includes an 8-bit A/D converter, 8-channel multiplexer, 8 x 8 dual port RAM with contention logic, and microprocessor compatible I/O logic. When combined with a voltage reference, a complete data acquisition system is produced that interfaces with the majority of microprocessors. Conversions take place on a continuous, channel sequencing basis using a microprocessor clock or control signal. Data is stored automatically in dual port RAM so that any channel can be read at any time under microprocessor control. The MAX161 is an enhanced, pin-compatible version of the MX7581. Improvements include faster conversion and interface timing, lower zero error and drift, reduced power dissipation, and availability in military temperature grades. All devices are available in 28 pin DIP and Small Outiline (SO) packages.
