MAX172BEWG

Analog To Digital Converters (ADC) Overview

The MAX172BEWG is a high-speed, 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes successive approximation register (SAR) architecture to achieve a sampling rate of 100 kS/s with a single-ended input configuration. The device features an internal reference voltage and operates on a parallel CMOS interface. Designed for industrial environments, it supports supply voltages up to 5.25 V and functions within a temperature range of -40°C to +85°C. Housed in a 24-lead SOIC package, the component offers differential nonlinearity of ±1 LSB and integral nonlinearity of ±1 LSB, ensuring precise data conversion capabilities.

• Medical instrumentation applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'EWG' indicates the 24-SOIC surface-mount package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check current availability as distribution channels may list limited stock or end-of-life statuses for this specific Maxim Integrated part number.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX172BEWG when a single-channel, 12-bit ADC with parallel interface is required for moderate-speed applications. Ensure the design accommodates the 24-SOIC footprint and parallel data bus connections. Compare against the MAX172AENG+ if through-hole mounting is preferred instead of surface mount technology.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX172 family of complete 10s CMOS 12-bit ADCs. The BEWG suffix specifically denotes the commercial/industrial temperature grade version packaged in a 24-lead small outline integrated circuit (SOIC). It serves as a surface-mount alternative to the PDIP variants within the same performance class.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX172BEWG+T is a tape-and-reel variant of the same electrical specification. For through-hole requirements, the MAX172AENG+ offers identical performance in a DIP package. Verify pin compatibility before substituting with other 12-bit SAR ADCs.
