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 multi-channel input sampling. This device features a Successive Approximation Register (SAR) architecture with configurable 2 or 4 input channels, supporting both differential and single-ended input types via SPI data interface.

The MAX1246BEEE is classified as obsolete. Finding equivalent substitute parts is necessary to ensure continued availability for new designs, system maintenance, and production continuity where original inventory becomes depleted or unavailable.

Substitute Part Grouping Explanation

Substitute parts for the MAX1246BEEE are identified based on strict parametric equivalence across electrical and mechanical specifications. The following parameters determine substitution eligibility:

• Resolution: 12 bits
• Sampling Rate: 133 kSPS
• Input Channel Configuration: 2 or 4 channels
• Input Type Support: Differential and single-ended
• Data Interface: SPI protocol
• SAR Architecture
• Supply Voltage Ranges: Analog 2.7V ~ 3.6V, Digital 2.7V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C
• Package: 16-SSOP form factor
• Mounting: Surface mount

The MAX1246AEEE+ meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The MAX1246AEEE+ is the direct parametric equivalent for the MAX1246BEEE. Both devices share identical electrical specifications, pin configuration, and functional characteristics. The primary distinction is product lifecycle status: the MAX1246BEEE is obsolete, while the MAX1246AEEE+ is active and currently in production.

For new designs and ongoing production requirements, the MAX1246AEEE+ is the appropriate selection. This part maintains full compatibility with existing MAX1246BEEE designs without circuit modification. Additionally, the MAX1246AEEE+ offers improved regulatory compliance, meeting ROHS3 requirements compared to the non-compliant status of the original part.

Frequently Asked Questions (FAQ)

Q: Can the MAX1246AEEE+ directly replace the MAX1246BEEE in existing designs?

A: Yes. The MAX1246AEEE+ is a parametric equivalent with identical pin configuration, electrical specifications, and functional performance. No circuit modifications are required for substitution.

Q: What is the difference between the MAX1246BEEE and MAX1246AEEE+?

A: The devices are electrically and functionally identical. The primary differences are product status (obsolete versus active) and regulatory compliance (RoHS non-compliant versus ROHS3 compliant). The MAX1246AEEE+ is supplied in tube packaging.

Q: Are there any compatibility concerns with the 16-SSOP package?

A: No. Both parts use the identical 16-SSOP (0.154", 3.90mm Width) surface mount package. PCB footprints and assembly processes remain unchanged.

Q: Does the MAX1246AEEE+ support the same input configurations?

A: Yes. Both parts support 2 or 4 input channels with differential and single-ended input types, identical SPI data interface, and SAR architecture.

Q: What supply voltage requirements apply to the MAX1246AEEE+?

A: The MAX1246AEEE+ requires analog and digital supply voltages in the range of 2.7V to 3.6V, matching the MAX1246BEEE specifications exactly.
