MAX197ACAI+T

ADCs/DACs - Special Purpose Overview

The MAX197ACAI+T is a multi-range, 12-bit data-acquisition system (DAS) requiring a single +5V supply. It features eight independently software-programmable analog input channels supporting ±10V, ±5V, 0V to +10V, or 0V to +5V ranges. The device provides an effective dynamic range of 14 bits and includes overvoltage protection up to ±16.5V. Key electrical specifications include a 100ksps throughput rate, 6µs conversion time, and a 5MHz bandwidth track/hold circuit. It utilizes an 8+4 parallel interface with TTL/CMOS compatible logic inputs and outputs.

ADCs/DACs - Special Purpose Procurement Notes

Verify the 'T' suffix indicates tape-and-reel packaging when sourcing this component. Confirm that the AC grade meets the required linearity specifications for the application. Ensure the SSOP-28 package footprint matches the design constraints. Check for RoHS compliance status as indicated in current distributor listings.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX197ACAI+T for applications requiring high-speed sampling at 100ksps with 12-bit resolution. The internal reference simplifies design by eliminating external components, though an external reference can be used via the REF pin. Consider the 8+4 bus interface compatibility with the target microprocessor. Verify that the input signal ranges align with the programmable options to maximize dynamic range.

ADCs/DACs - Special Purpose Part Context

The MAX197 series consists of multi-range, 12-bit DAS devices from Analog Devices / Maxim Integrated. The MAX197ACAI+T specifically denotes the AC temperature grade (0°C to +70°C) in an SSOP-28 package. This part is part of a family that includes variations like the MAX197BCWI+ and MAX197AENI+, differing in temperature range and package type.

ADCs/DACs - Special Purpose Replacement Considerations

For different input ranges (±4V, ±2V, 0V to 4V, 0V to 2V), refer to the MAX199 data sheet. For 12-bit bus interfaces, consider the MAX196 and MAX198 data sheets. No direct public substitute part numbers are confirmed for this specific variant.
