The parallel data interface connects directly to an MCU or DSP bus without a serial bridge. Eight analog input channels cover multi-sensor front-ends without an external mux. Single-supply operation uses one 5V rail for the ADC core and analog front-end.
The MAX197BEAI+ is listed as Active and ROHS3 compliant. For new designs, the part is still a valid selection — no forced migration risk.
The MAX197BEAI+ is a specific variant of the MAX197 family. The 'B' grade typically specifies the industrial temperature range (-40°C to 85°C), and the 'EAI+' suffix denotes the 28-SSOP package and ROHS3 compliance. Functionally it is the same 12-bit, 8-channel DAS core as the base MAX197, but the package and temperature grade differ from other suffixes (e.g., MAX197ACNI in DIP). Verify the package and temperature range against your BOM before substituting.
No newer direct pin-compatible replacement has been announced by Analog Devices for the MAX197BEAI+. The part remains Active. If you need a higher sampling rate or more channels, you would need to re-evaluate the pinout and interface — no drop-in upgrade exists within the same package.
