MAX197AEWI+T

ADCs/DACs - Special Purpose Overview

The MAX197AEWI+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 provides a 100ksps throughput rate with a 6µs conversion time and includes an internal 4.096V reference or external reference capability. It utilizes an 8+4 parallel bus interface and offers overvoltage protection up to ±16.5V on all inputs.

ADCs/DACs - Special Purpose Procurement Notes

Verify the 'T' suffix indicates tape-and-reel packaging by consulting the manufacturer's official documentation. Confirm the specific temperature grade associated with the 'A' designation in the ordering information table. Ensure compatibility with the 28-pin Wide SO package dimensions before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a single +5V supply is required for multi-range signal conditioning. The internal track/hold circuit supports 5MHz bandwidth. Consider the 8+4 multiplexed parallel interface for microprocessor integration. Verify that the ±16.5V overvoltage tolerance meets the application's fault conditions.

ADCs/DACs - Special Purpose Part Context

The MAX197 series includes variants such as MAX197ACNI and MAX197BCWI. The 'A' grade typically denotes specific linearity performance compared to the 'B' grade. The 'E' grade extends the operating temperature range to -40°C to +85°C. This part belongs to the Maxim Integrated DAS family.

ADCs/DACs - Special Purpose Replacement Considerations

For different input ranges (±4V, ±2V), refer to the MAX199. For 12-bit bus interfaces, consider the MAX196 or MAX198. Check for pin-compatible alternatives within the same package type if sourcing constraints exist.
