MAX198BCWI+

ADCs/DACs - Special Purpose Overview

The MAX198BCWI+ 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, 0 to VREF, and 0 to VREF/2. The device features a 100ksps throughput rate, 5MHz track/hold bandwidth, and fault protection up to ±16.5V. It includes an internal 4.096V reference or external reference capability, two power-down modes, and a 12-bit parallel interface. Packaged in a 28-pin Wide SOIC, it functions within a temperature range of 0°C to +70°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'WI+' indicates the Wide SOIC package and commercial temperature grade. Confirm RoHS compliance status via current manufacturer documentation. Check for end-of-life notifications as older Maxim products may have discontinuation notices. Ensure the ordering part number matches the exact pin count and thermal specifications required for the design.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a single-supply 12-bit ADC with multiple programmable voltage ranges is required. The MAX198 differs from the MAX196 by using direct reference scaling rather than internal gain factors for input ranges. Ensure the application can accommodate the 28-pin Wide SOIC footprint. Verify that the 100ksps throughput and 5MHz bandwidth meet the signal processing requirements.

ADCs/DACs - Special Purpose Part Context

This device belongs to the MAX196/MAX198 family of multirange, single-supply data acquisition systems. It shares architectural similarities with the MAX197 and MAX199 but offers a 12-bit bus interface. The MAX198 variant is specifically designed for applications requiring input ranges directly proportional to the reference voltage without internal scaling factors.
