MAX198BENI+

ADCs/DACs - Special Purpose Overview

The MAX198BENI+ 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 includes an internal 4.096V reference or external reference capability, two power-down modes, and a 12-bit parallel interface. The component is housed in a 28-pin DIP package with an operating temperature range of 0°C to +70°C.

ADCs/DACs - Special Purpose Applications

• Industrial-Control Systems
• Robotics
• Data-Acquisition Systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'NI+' against the manufacturer's current product status documentation. Datasheets indicate that certain MAX198 variants have reached end-of-life status. Confirm availability through official Analog Devices channels rather than third-party distributors, as stock levels may be limited or discontinued.

ADCs/DACs - Special Purpose Selection Notes

Select the MAX198BENI+ when a multirange ADC is required for ±VREF-based signals. Ensure the design accommodates the 28-pin DIP footprint. Verify that the system clock requirements align with the internal or external clock options. Check if the ±16.5V fault protection meets the input signal constraints.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX196/MAX198 family of multirange, single-supply DAS devices. The MAX198 variant specifically uses the reference voltage directly for range selection, unlike the MAX196 which uses scaling factors. The 'E' suffix denotes the commercial temperature grade (0°C to +70°C), while 'NI' indicates the narrow plastic DIP package.
