MAX197BCAI

ADCs/DACs - Special Purpose Overview

The MAX197BCAI 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 programmable analog input channels supporting ranges of ±10V, ±5V, 0V to +10V, or 0V to +5V. It provides a 100ksps throughput rate with a 6µs conversion time and includes an internal 4.096V reference or external reference capability. The component utilizes a standard 8+4 parallel bus interface and is housed in a 28-pin SSOP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'CAI' corresponds to the 28-pin SSOP package and commercial temperature range (0°C to +70°C). Confirm RoHS compliance status for the specific manufacturing lot. Ensure the source document matches the official Maxim Integrated datasheet revision. Check for obsolescence notices as older variants may be discontinued.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX197BCAI when a 12-bit resolution and 100ksps throughput are required within a single +5V system. Choose this part over the MAX197ACAI if higher accuracy specifications (such as tighter gain error and INL limits) are necessary. Ensure the application requires the 28-pin SSOP form factor and operates within the 0°C to +70°C temperature range.

ADCs/DACs - Special Purpose Part Context

The MAX197BCAI belongs to the MAX197 family of multi-range data acquisition systems. It shares the core architecture with the MAX197ACAI but offers improved linearity and gain error specifications. The 'B' grade indicates tighter performance tolerances compared to the 'A' grade. It is distinct from the MAX196 and MAX198, which feature different bus interfaces.

ADCs/DACs - Special Purpose Replacement Considerations

The MAX197ACAI is a lower-specification alternative within the same package. For pin-compatible replacements with different accuracy grades, consult the MAX197 ordering information table. No direct cross-model substitutes with different interfaces are confirmed.
