MAX197BENI

ADCs/DACs - Special Purpose Overview

The MAX197BENI 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 power-supply rail and below ground. The device features eight independently software-programmable analog input channels with selectable ranges: ±10V, ±5V, 0V to +10V, or 0V to +5V. This configuration increases the effective dynamic range to 14 bits. Key electrical specifications include a 100ksps throughput rate, 6µs conversion time, and overvoltage tolerance of ±16.5V on all input channels.

ADCs/DACs - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements prior to procurement. Ensure storage conditions adhere to specified humidity sensitivity levels to maintain device reliability during assembly.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX197BENI for applications requiring high-speed, multi-channel signal acquisition with flexible input voltage ranges. Ensure the design supports a single +5V supply and accommodates the 28-pin DIP package dimensions. Verify that the microprocessor interface timing aligns with the device's parallel bus specifications and TTL/CMOS compatibility requirements.

ADCs/DACs - Special Purpose Part Context

The MAX197 series includes variants such as MAX197ACNI, MAX197BCNI, and MAX197BEAI, differing primarily in temperature ranges and package types. The MAX197BENI specifically denotes the industrial temperature grade (-40°C to +85°C) housed in a 28-pin Narrow Plastic DIP package. It belongs to the broader MAX197 family of multi-range DAS devices.

ADCs/DACs - Special Purpose Replacement Considerations

For alternative input ranges (±4V, ±2V, 0V to 4V, 0V to 2V), consider the MAX199. For 12-bit bus interface alternatives, refer to the MAX196 and MAX198 datasheets. Direct pin-compatible replacements within the same package and temperature grade should be verified against current availability and updated specification sheets.
