MAX1246BEEE+ Equivalent & Substitute Parts

Part Overview

The MAX1246BEEE+ is a 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring serial interface communication. This device features a successive approximation register (SAR) architecture with configurable input channels (2 or 4) supporting both differential and single-ended inputs. The part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing production and design continuity.

Substitute Part Grouping Explanation

Substitution of the MAX1246BEEE+ is determined by strict equivalence across the following critical parameters:

  • Resolution & Sampling Rate: 12-bit resolution at 133 kSPS
  • Input Configuration: Support for 2 or 4 input channels with differential and single-ended input types
  • Serial Interface: SPI data interface protocol
  • Architecture: SAR-based analog-to-digital conversion
  • Reference Options: Both external and internal reference capability
  • Supply Voltage Range: 2.7V to 3.6V for both analog and digital supplies
  • Operating Temperature: -40°C to 85°C range
  • Package & Pinout: 16-SSOP surface mount package with identical mechanical dimensions

The MAX1246AEEE+ meets all these criteria as a parametric equivalent, with the primary distinction being product status (active versus obsolete) and packaging format (tube versus unspecified for the original part).
