MAX198BEAI

Analog To Digital Converters (ADC) Overview

The MAX198BEAI is a multirange, 12-bit data-acquisition system (DAS) requiring a single +5V supply. It features six analog input channels independently programmable for ranges including ±VREF, ±VREF/2, 0V to +VREF, and 0V to +VREF/2. The device provides fault protection up to ±16.5V, a 5MHz bandwidth track/hold, and a 100ksps throughput rate. It utilizes a 12-bit parallel interface with TTL/CMOS compatible logic inputs and outputs.

Analog To Digital Converters (ADC) Feature Summary

• Software-selectable input ranges enable flexible interfacing with various sensor types without external scaling components.
• Integrated fault-protected input multiplexer safeguards against overvoltage conditions on any channel.
• Dual power-down modes allow for low-current shutdown while maintaining reference buffer activity in standby mode.

Analog To Digital Converters (ADC) Applications

• Industrial-Control Systems
• Data-Acquisition Systems
• Automatic Testing Systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BEAI corresponds to the commercial temperature range of 0°C to +70°C and the SSOP package type as documented in the official Analog Devices ordering information. Confirm RoHS compliance status and current availability through authorized distributors, as older Maxim Integrated products may have end-of-life statuses.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX198BEAI when bipolar or unipolar input ranges relative to the reference voltage are required, distinguishing it from the MAX196 which uses fixed voltage scaling factors. Ensure the application supports a single +5V supply and requires a 12-bit parallel interface compatible with standard microprocessors.

Analog To Digital Converters (ADC) Part Context

The MAX198BEAI belongs to the MAX196/MAX198 family of multirange, 12-bit data-acquisition systems manufactured by Analog Devices Inc./Maxim Integrated. These devices share core architecture but differ in input range programming methods, with the MAX198 offering direct reference-relative ranges.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider evaluating the MAX196 series for similar functionality if input range requirements align with its fixed scaling specifications.
