MAX198AENI+ is listed in the ADCs/DACs - Special Purpose range at ChipApex. The manufacturer field lists Analog Devices Inc./Maxim Integrated. Its product description is IC DAS 12BIT 100K 28DIP. Review the specifications below when checking this part for your BOM.
The MAX198AENI+ is a 12-bit, 6-channel data-acquisition system (DAS) from Analog Devices/Maxim Integrated. It operates on a single +5V supply and supports software-selectable input ranges of ±VREF, ±VREF/2, 0V to +VREF, and 0V to +VREF/2. The device features a 100ksps throughput rate, 5MHz track/hold bandwidth, and fault protection up to ±16.5V. It utilizes a 12-bit parallel interface with internal or external clock options and includes two power-down modes for low-current shutdown.
Verify the component status as the MAX198 family has been subject to product discontinuation notices. Confirm availability through authorized distributors and check for RoHS compliance markings on the specific batch. Ensure the ordering suffix matches the required package and temperature range specifications.
Select the MAX198AENI+ when a 12-bit resolution and 100ksps sampling rate are required for single-supply applications. Choose this part over the MAX196 if the application requires input ranges directly proportional to the reference voltage rather than scaled ranges. Verify that the 28-pin DIP package fits the PCB layout constraints.
The MAX198AENI+ belongs to the MAX196/MAX198 series of multirange, single +5V, 12-bit DAS devices. It shares architectural similarities with the MAX197 and MAX199 but differs in channel count and bus interface width. The 'A' grade indicates specific accuracy limits, while 'ENI' denotes the 28-pin Narrow Plastic DIP package and industrial/commercial temperature range.
