MAX197ACAI

ADCs/DACs - Special Purpose Overview

The MAX197ACAI is a multi-range, 12-bit data-acquisition system (DAS) housed in a 28-pin SSOP package. Operating on a single +5V supply, it features eight analog input channels with software-selectable ranges: ±10V, ±5V, 0V to +10V, or 0V to +5V. The device provides a throughput rate of 100ksps with a conversion time of 6µs and includes an internal 4.096V reference or external reference capability. It offers fault-protected inputs tolerant to ±16.5V and supports both internal and external clock/acquisition control modes.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'CAI' corresponds to the 28-pin SSOP package and 0°C to +70°C temperature range as listed in the ordering information. Confirm that the component meets the required thermal dissipation limits for the SSOP package, which derates at 9.52mW/°C above +70°C. Ensure compatibility with the intended microprocessor interface timing specifications.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX197ACAI when a compact SSOP footprint is required alongside standard 12-bit resolution and multi-range input capabilities. Consider the internal clock mode if freeing up the microprocessor from generating conversion clocks is necessary. Verify that the input signal ranges align with the available ±10V, ±5V, 0V to +10V, or 0V to +5V configurations.

ADCs/DACs - Special Purpose Part Context

The MAX197ACAI belongs to the MAX197 family of multi-range data acquisition systems. It shares core functionalities with other variants like the MAX197ACNI (DIP) and MAX197ACWI (SOIC), differing primarily in package type. This series is designed for applications requiring flexible analog input interfacing within a single +5V system architecture.

ADCs/DACs - Special Purpose Replacement Considerations

For alternative packages within the same electrical specification, consider the MAX197ACNI (28-PDIP) or MAX197ACWI (28-SOIC). For different input range combinations such as ±4V or ±2V, refer to the MAX199 datasheet. For 12-bit bus interfaces with different pinouts, consult the MAX196 or MAX198 datasheets.
