MAX196BEAI+

ADCs/DACs - Special Purpose Overview

The MAX196BEAI+ is a multirange, 12-bit data-acquisition system (DAS) from Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply while accepting analog input signals up to ±10V. The device features six independently programmable analog input channels with software-selectable ranges: ±10V, ±5V, 0V to +10V, and 0V to +5V. It provides a 12-bit parallel interface, a 5MHz bandwidth track/hold circuit, and a throughput rate of 100ksps. The unit includes an internal 4.096V reference or supports external references, offering fault protection to ±16.5V on all inputs.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) compared to the standard industrial grade. Confirm the 'A' suffix corresponds to the SSOP package variant. Ensure the '+' suffix denotes RoHS compliance status as per manufacturer specifications. Cross-reference the full part number against official distributor catalogs to confirm current availability and lead times.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high channel count in a compact surface-mount package. The MAX196BEAI+ offers a 28-pin SSOP footprint, which is 55% smaller than the wide SO package. Consider the internal clock capability if microprocessor clock generation resources are limited. Evaluate power-down modes (STBYPD and FULLPD) for systems requiring low standby current between conversions.

ADCs/DACs - Special Purpose Part Context

The MAX196BEAI+ belongs to the MAX196/MAX198 family of multirange DAS devices. The MAX196 variant supports bipolar and unipolar ranges up to ±10V, whereas the MAX198 supports ranges based on the reference voltage. This specific part integrates the ADC, multiplexer, and track/hold circuit into a single monolithic chip, simplifying board design for multi-channel acquisition tasks.

ADCs/DACs - Special Purpose Replacement Considerations

Direct substitutes within the same family include the MAX196ACAI+ (industrial temperature range) or MAX196BCNI+ (plastic DIP package). For pin-compatible alternatives with different performance characteristics, consult the MAX197 or MAX199 datasheets, though these feature an 8+4 bus interface rather than the 12-bit parallel interface found in the MAX196 series.
