MAX197ACNI

ADCs/DACs - Special Purpose Overview

The MAX197ACNI 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 100ksps throughput with a 6µs conversion time and includes an internal 4.096V reference or external reference capability. Input channels are fault-protected to ±16.5V. It utilizes an 8+4 parallel interface compatible with TTL/CMOS logic and operates within a commercial temperature range of 0°C to +70°C in a 28-pin narrow plastic DIP package.

ADCs/DACs - Special Purpose Feature Summary

• 12-bit resolution with ±1/2 LSB integral nonlinearity
• Software-selectable input ranges: ±10V, ±5V, 0V to +10V, 0V to +5V
• Eight analog input channels with ±16.5V overvoltage protection
• Internal or external acquisition control modes

ADCs/DACs - Special Purpose Applications

• Industrial-control systems
• Data-acquisition systems
• Automatic testing systems
• Medical instruments

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix ACNI corresponds to the 28-pin narrow plastic DIP package and the 0°C to +70°C operating temperature range. Confirm RoHS compliance status as historical documentation may vary. Ensure the source document explicitly lists this part number to avoid confusion with other package variants like SO or SSOP.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX197ACNI when a 28-pin through-hole DIP package is required for PCB layout. This variant supports the same electrical specifications as other MAX197 packages but differs in physical form factor. Verify that the application environment remains within the 0°C to +70°C commercial temperature limits.

ADCs/DACs - Special Purpose Part Context

The MAX197ACNI belongs to the MAX197A series of multi-range data acquisition systems. It shares core functionality with variants such as MAX197ACWI (SOIC) and MAX197ACAI (SSOP), differing primarily in packaging. The 'C' designation indicates the commercial temperature grade, while 'NI' specifies the narrow plastic DIP enclosure.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements include MAX197BCNI for improved linearity specifications within the same package. Other package variants like MAX197ACWI or MAX197ACAI offer identical electrical performance but require different footprint considerations.
