MAX197BCWI

ADCs/DACs - Special Purpose Overview

The MAX197BCWI is a multi-range, 12-bit data-acquisition system (DAS) from Analog Devices/Maxim Integrated. It operates on a single +5V supply while accepting analog inputs 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 an 8+4 parallel bus interface and offers fault protection up to ±16.5V.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'BC' indicates the commercial temperature grade (0°C to +70°C) and 'WI' denotes the 28-pin Wide SO package. Confirm RoHS compliance status for the '+' suffix variant if required by assembly specifications. Check current availability as legacy components may have limited stock or obsolescence notices.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX197BCWI when a 12-bit ADC with multi-range input flexibility is required in a single-supply environment. Ensure the application supports the 8+4 parallel interface timing constraints. Consider the internal reference stability versus external precision requirements. Verify that the 100ksps sampling rate meets the signal bandwidth needs without excessive aliasing.

ADCs/DACs - Special Purpose Part Context

The MAX197 series includes variants like MAX196, MAX198, and MAX199. The MAX199 offers different range combinations (±4V, ±2V, etc.). The MAX196 and MAX198 provide 12-bit bus interfaces. The MAX197BCWI specifically targets applications needing ±10V, ±5V, 0-10V, and 0-5V ranges in a wide SOIC package.
