MAX199BCWI+

ADCs/DACs - Special Purpose Overview

The MAX199BCWI+ 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 input channels. The device features software-selectable ranges including ±VREF, ±VREF/2, 0V to VREF, and 0V to VREF/2, effectively increasing dynamic range to 14 bits. Key specifications include a 100ksps throughput rate, 6µs conversion time, and fault protection for inputs up to ±16.5V. It utilizes an 8+4 parallel bus interface and supports internal or external clocking.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'WI+' against current manufacturer documentation to confirm package type (Wide SOIC) and compliance status. Confirm availability as this component family may have limited stock or obsolescence notices. Ensure the ordering information matches the required temperature range of 0°C to +70°C.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX199BCWI+ when a 12-bit resolution with high linearity is required for single-supply applications. The Wide SO package is suitable for surface-mount designs requiring specific thermal or spatial constraints. Verify that the ±16.5V fault protection meets the input signal requirements and that the 100ksps throughput aligns with system bandwidth needs.

ADCs/DACs - Special Purpose Part Context

The MAX199BCWI+ belongs to the MAX199 series of multi-range data acquisition systems. It is part of a broader family that includes variations in accuracy grades (A, B), packages (DIP, SSOP, Ceramic SB), and temperature ranges. This specific model represents the B-grade accuracy version in a Wide SOIC package.

ADCs/DACs - Special Purpose Replacement Considerations

For alternative options, consult the MAX197 data sheet for different input ranges (±10V, ±5V, 0V to 10V, 0V to 5V). For 12-bit bus interfaces, refer to the MAX196/MAX198 data sheets. Direct pin-compatible replacements should be verified through official distributor cross-reference tools.
