产品概述

The MAX199 multi-range, 12-bit data-acquisition system(DAS) requires only a single +5V supply for operation,and converts analog signals up to ±4V at its inputs. Thissystem provides eight analog input channels that areindependently software programmable for a variety ofranges: ±VREF, ±VREF/2, 0V to VREF, or 0V to VREF/2.This increases effective dynamic range to 14 bits, andprovides the user flexibility to interface 4mA-to-20mA,±12V, and ±15V powered sensors to a single +5V system.In addition, the converter is fault-protected to±16.5V; a fault condition on any channel will not affectthe conversion result of the selected channel. Other featuresinclude a 5MHz bandwidth track/hold, 100kspsthroughput rate, internal/external clock, internal/externalacquisition control, 8+4 parallel interface, and operationwith an internal 4.096V or external reference.

A hardware active-low SHDN pin and two programmable power-downmodes (STBYPD, FULLPD) provide low-currentshutdown between conversions. In STBYPD mode, thereference buffer remains active, eliminating start-updelays.

The MAX199 employs a standard microprocessor (µP)interface. Its three-state data I/O interface is configuredto operate with 8-bit data buses, and data-access andbus-release timing specifications are compatible withmost popular µPs. All logic inputs and outputs areTTL/CMOS compatible.

The MAX199 is available in 28-pin DIP, wide SO, SSOP,and ceramic SB packages.

For a different combination of input ranges (±10V, ±5V,0V to 10V, 0V to 5V), see the MAX197 data sheet. For 12-bit bus interfaces, see the MAX196/MAX198 data sheet.
