MAX199ACWI+

ADCs/DACs - Special Purpose Overview

The MAX199ACWI+ is a multi-range, 12-bit data-acquisition system (DAS) from Analog Devices/Maxim Integrated. It operates on a single +5V supply and converts analog signals up to ±4V across eight independently programmable channels. The device features software-selectable input ranges including ±VREF, ±VREF/2, 0V to VREF, and 0V to VREF/2, effectively increasing dynamic range to 14 bits. Key electrical specifications include a 100ksps throughput rate, 6µs conversion time, and a 5MHz track/hold bandwidth. It utilizes an internal or external reference and provides fault protection to ±16.5V.

ADCs/DACs - Special Purpose Procurement Notes

Verify the component status as obsolete based on distributor records. Confirm the package type is 28-Wide SOIC and the operating temperature range is 0°C to +70°C. Ensure compatibility with TTL/CMOS logic levels for the parallel interface. Check for RoHS compliance if required by specific manufacturing standards.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a single-supply, multi-channel ADC with flexible input ranging is required. It is suitable for interfacing sensors such as 4mA-to-20mA transmitters or ±12V/±15V powered devices directly to a +5V system. Consider the 8+4 parallel bus interface for microprocessor integration and verify that the 100ksps throughput meets the application's sampling requirements.

ADCs/DACs - Special Purpose Part Context

The MAX199ACWI+ belongs to the MAX199A series of data acquisition systems. It is part of a family that includes variants like the MAX197 and MAX196/MAX198 for different input range combinations or bus interfaces. The 'AC' suffix indicates the commercial temperature grade (0°C to +70°C), while 'WI' denotes the 28-pin Wide SOIC package.

ADCs/DACs - Special Purpose Replacement Considerations

For different input ranges such as ±10V or ±5V, consult the MAX197 datasheet. For 12-bit bus interfaces with alternative configurations, refer to the MAX196 or MAX198 datasheets. No direct pin-compatible substitutes are listed in the provided documentation.
