MAX196ACAI+T

ADCs/DACs - Special Purpose Overview

The MAX196ACAI+T is a multirange, single +5V, 12-bit data-acquisition system (DAS) from Analog Devices/Maxim Integrated. It integrates six independently software-programmable analog input channels with a successive approximation register (SAR) architecture. The device supports input ranges of ±10V, ±5V, 0V to +10V, and 0V to +5V for the MAX196 variant, effectively increasing dynamic range to 14 bits. Key electrical specifications include a 100ksps throughput rate, 6µs conversion time, and fault-protected inputs rated to ±16.5V. It operates on a single +5V supply with an internal 4.096V reference or external reference option.

ADCs/DACs - Special Purpose Feature Summary

• Six analog input channels with software-selectable unipolar/bipolar ranges (±10V, ±5V, 0–10V, 0–5V).
• 12-bit resolution with 1/2 LSB integral nonlinearity and 100ksps sampling throughput.
• Fault-protected input multiplexer tolerant to ±16.5V overvoltage conditions.
• Dual power-down modes (STBYPD and FULLPD) for low-current shutdown.

ADCs/DACs - Special Purpose Applications

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

ADCs/DACs - Special Purpose Procurement Notes

Verify the ordering suffix '+T' against official documentation to confirm tape-and-reel packaging status, as standard datasheets may list bulk or tube variants. Confirm RoHS compliance and lead-free status via the manufacturer's current product change notices. Ensure the specific temperature grade matches the application requirements.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring multi-channel acquisition with varying input voltage scales without external scaling circuitry. The internal track/hold amplifier requires a low-impedance source for bipolar ranges at maximum speed. Consider the 28-pin SSOP package constraints for thermal dissipation and board space compared to DIP or SOIC options.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX196/MAX198 family of multirange DAS devices. The 'A' suffix denotes the commercial temperature grade (0°C to +70°C), while 'I' indicates industrial (-40°C to +85°C) and 'M' indicates military (-55°C to +125°C). The 'ACAI' designation specifies the A-grade performance in a 28-pin SSOP package.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements within the same family include MAX196BCAI+ (higher accuracy grade) or MAX196AEAI+ (industrial temperature range). Verify that the replacement maintains the 12-bit parallel interface timing and power-down mode compatibility.
