MAX199BCNI+

ADCs/DACs - Special Purpose Overview

The MAX199BCNI+ is a multi-range, 12-bit data-acquisition system (DAS) requiring a single +5V supply. It features eight analog input channels independently programmable for ranges of ±VREF, ±VREF/2, 0V to VREF, or 0V to VREF/2, increasing effective dynamic range to 14 bits. The device includes a 5MHz bandwidth track/hold, 100ksps throughput rate, and an 8+4 parallel interface. It operates with internal or external references and offers fault protection to ±16.5V on inputs.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'BCNI+' corresponds to the 28-pin Narrow Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm RoHS compliance status as indicated in current distributor listings. Check for obsolescence notices from Analog Devices/Maxim Integrated prior to finalizing procurement plans.

ADCs/DACs - Special Purpose Selection Notes

Select this component when interfacing sensors such as 4mA-to-20mA or ±12V/±15V devices to a single +5V system. Ensure the application requires software-selectable input ranges to maximize dynamic range. Verify that the microprocessor interface timing specifications are compatible with the target system's bus release and access requirements.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX199A series of multi-range DAS devices. The 'B' suffix indicates specific accuracy grades compared to the 'A' variant. The 'C' denotes the commercial temperature range, while 'E' would indicate extended range. The 'NI' suffix specifies the 28-pin narrow plastic DIP package type.

ADCs/DACs - Special Purpose Replacement Considerations

For different input ranges (±10V, ±5V), consult the MAX197 datasheet. For 12-bit bus interfaces with different configurations, review the MAX196/MAX198 datasheets. Direct pin-compatible replacements within the same package and temperature grade should be verified against current Analog Devices product portfolios.
