MAX197BCWI+T is listed in the ADCs/DACs - Special Purpose range at ChipApex. The manufacturer field lists Analog Devices Inc./Maxim Integrated. Its product description is IC DAS 12BIT 100K 28SOIC. Review the specifications below when checking this part for your BOM.
The MAX197BCWI+T is a multi-range, 12-bit data-acquisition system (DAS) requiring a single +5V supply. It features eight analog input channels independently programmable for ±10V, ±5V, 0V to +10V, or 0V to +5V ranges. The device offers a 100ksps throughput rate with a 6µs conversion time and supports internal or external clocking. It includes an 8+4 parallel bus interface, fault-protected inputs tolerant to ±16.5V, and two power-down modes. The component operates within a temperature range of 0°C to +70°C and is housed in a 28-pin Wide SO package.
Verify the specific suffix 'T' indicates reel packaging when sourcing. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the BC grade specifications match the required linearity performance for the application. Check current availability status as this component may be subject to discontinuation notices from the manufacturer.
Select the MAX197BCWI+T for applications requiring ±1/2 LSB INL accuracy. Choose this part over the AC grade if tighter integral nonlinearity specifications are necessary. Ensure the design accommodates the 28-pin Wide SO package dimensions. Verify that the system logic levels are compatible with the TTL/CMOS interface requirements.
This component belongs to the MAX197 family of multi-range data acquisition systems. It shares functional similarities with the MAX196 and MAX198 but utilizes an 8+4 parallel bus interface rather than a full 12-bit bus. It differs from the MAX199, which offers alternative voltage ranges such as ±4V and ±2V.
Public confirmed substitute part numbers: MAX197ACWI+T.
