MAX197BCAI+T

ADCs/DACs - Special Purpose Overview

The MAX197BCAI+T is a multi-range, 12-bit data-acquisition system (DAS) from Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply while accepting analog input signals spanning above the rail and below ground. The device features eight independently software-programmable analog input channels with selectable ranges of ±10V, ±5V, 0V to +10V, or 0V to +5V. Key electrical parameters include a 100ksps throughput rate, 6µs conversion time, and 1/2LSB linearity. It utilizes an 8+4 parallel bus interface and includes internal or external reference options.

ADCs/DACs - Special Purpose Procurement Notes

Verify the ordering suffix '+T' indicates tape-and-reel packaging rather than tube packaging. Confirm the 'C' temperature range corresponds to 0°C to +70°C. Ensure compatibility with the specific package type associated with the 'A' suffix in the official datasheet.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring multi-range input flexibility without dual supplies. The internal track/hold circuit provides a 5MHz bandwidth. Consider the 8+4 multiplexed parallel interface for microprocessor integration. Verify power-down mode requirements against STBYPD and FULLPD specifications.

ADCs/DACs - Special Purpose Part Context

The MAX197 is part of a family of multi-range DAS devices. Variants such as MAX196 and MAX198 offer different bus interfaces. The MAX199 provides alternative voltage ranges. This specific model integrates successive approximation architecture with fault-tolerant input multiplexing.

ADCs/DACs - Special Purpose Replacement Considerations

Direct substitutes within the same family include MAX196 and MAX198, though they differ in bus interface configuration. For different input ranges, refer to the MAX199 datasheet.
