MAX196AEWI+

ADCs/DACs - Special Purpose Overview

The MAX196AEWI+ is a multirange, single +5V, 12-bit data-acquisition system (DAS) from Analog Devices/Maxim Integrated. It integrates six analog input channels with independently software-programmable ranges: ±10V, ±5V, 0V to +10V, and 0V to +5V. The device features a 100ksps throughput rate, 5MHz bandwidth track/hold, and fault protection to ±16.5V. It operates on a single +5V supply while accepting inputs up to ±10V. Key specifications include 12-bit resolution, ±0.5 LSB INL, and ±1 LSB DNL. The unit utilizes a 12-bit parallel interface and supports internal or external clock and reference configurations.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'EWI+' against the manufacturer's current ordering guide to confirm package type (Wide SOIC), temperature range (Commercial 0°C to +70°C), and RoHS compliance status. Ensure the source document matches the exact part number to avoid confusion with similar variants like MAX196ACNI or MAX196BCAI which differ in package and performance grades.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring multi-range input flexibility without external scaling circuitry. The MAX196AEWI+ is suitable when a wide dynamic range is needed from a single +5V supply. Consider the 12-bit parallel interface requirements and the need for either internal or external clock sources. Verify that the 100ksps throughput meets the system's real-time processing constraints.

ADCs/DACs - Special Purpose Part Context

This device belongs to the MAX196/MAX198 family of multirange DAS. The MAX196 variant specifically supports ±10V and ±5V bipolar ranges alongside unipolar options, whereas the MAX198 uses the reference voltage directly for range setting. The 'A' grade indicates tighter linearity specifications compared to 'B' grade parts. The 'E' suffix denotes an extended industrial temperature range (-40°C to +85°C), while 'I' denotes commercial range (0°C to +70°C).

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible substitutes within the same family include MAX196ACWI+ and MAX196BCWI+. Note that 'C' grade parts have a commercial temperature range (0°C to +70°C), while 'E' grade covers -40°C to +85°C. 'B' grade parts may have slightly relaxed linearity specs (±1 LSB INL vs ±0.5 LSB). Check datasheets for specific electrical differences.
