MAX1248AEEE Equivalent & Substitute Parts

Part Overview

The MAX1248AEEE is a 10-bit Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring SAR (Successive Approximation Register) architecture. This component features 2 or 4 configurable input channels with both differential and single-ended input support, operating across a supply voltage range of 2.7V to 5.25V for both analog and digital domains.

The MAX1248AEEE is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement. Active alternatives with identical electrical and mechanical specifications are available to ensure design continuity and system compatibility.

Engineering Selection Recommendations

For new designs and ongoing procurement, MAX1248AEEE+ and MAX1248BEEE+ are the recommended substitutes due to their active product status and ROHS3 compliance. Both parts maintain complete electrical and mechanical equivalence to the obsolete MAX1248AEEE.

MAX1248AEEE+ provides direct substitution with identical specifications and is available in tube packaging. MAX1248BEEE+ offers the same functional performance and compliance profile, also supplied in tube packaging.

Selection between MAX1248AEEE+ and MAX1248BEEE+ should be based on availability and procurement lead times, as both parts satisfy all electrical and mechanical requirements for direct replacement applications.

Frequently Asked Questions (FAQ)

Q: Can MAX1248AEEE+ and MAX1248BEEE+ be used interchangeably with MAX1248AEEE?

A: Yes. Both substitute parts maintain identical electrical specifications, including 10-bit resolution, 133 kSPS sampling rate, SPI interface, SAR architecture, and 16-SSOP package dimensions. Direct PCB substitution is supported without circuit modification.

Q: What is the primary difference between MAX1248AEEE+ and MAX1248BEEE+?

A: Both parts are electrically and mechanically equivalent. The primary distinction is product availability and procurement status. Both are active products supplied in tube packaging with ROHS3 compliance.

Q: Why is the original MAX1248AEEE classified as obsolete?

A: The MAX1248AEEE is listed as obsolete by the manufacturer. Active alternatives with identical specifications are available to support continued system design and maintenance.

Q: Are there any compliance differences between the obsolete MAX1248AEEE and its substitutes?

A: Yes. The original MAX1248AEEE is RoHS non-compliant, while both MAX1248AEEE+ and MAX1248BEEE+ are ROHS3 compliant. Both substitutes maintain REACH Unaffected status and EAR99 ECCN classification.

Q: What packaging options are available for substitute parts?

A: Both MAX1248AEEE+ and MAX1248BEEE+ are supplied in tube packaging, compared to bulk packaging for the obsolete MAX1248AEEE. The 16-QSOP supplier device package remains consistent across all variants.

Q: Are the pin configurations identical across all three part numbers?

A: Yes. All three parts utilize the 16-SSOP package with identical pin assignments, enabling direct PCB-level substitution without layout modifications.
