Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX1246ACEE are identified based on strict parameter equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

• Resolution: 12 bits
• Sampling Rate: 133 kSPS
• Input Channels: 2, 4 configurable
• Input Configuration: Differential and Single Ended support
• Data Interface: SPI protocol
• Architecture: SAR topology
• Reference Options: External and Internal
• Supply Voltage Range: 2.7V ~ 3.6V (both analog and digital)
• Operating Temperature: 0°C ~ 70°C
• Package: 16-SSOP form factor
• Mounting: Surface Mount

All substitute parts maintain identical electrical performance and physical compatibility with the original MAX1246ACEE specification.

Engineering Selection Recommendations

The MAX1246ACEE is obsolete and no longer in active production. For new designs or replacement applications, MAX1246ACEE+ or MAX1246BCEE+ are the recommended alternatives.

MAX1246ACEE+ is the direct functional equivalent with identical electrical specifications and is currently in active production status. This part is ROHS3 compliant and available in tube packaging, making it suitable for both prototype and production environments.

MAX1246BCEE+ provides parametric equivalence with all electrical and mechanical specifications matching the original device. This part is also in active production, ROHS3 compliant, and available in tube packaging.

Both substitute parts maintain full compatibility with existing PCB layouts and firmware implementations designed for the MAX1246ACEE. The transition from the obsolete part to either active substitute requires no design modifications.

Frequently Asked Questions (FAQ)

Q: Can MAX1246ACEE+ be used as a direct replacement for MAX1246ACEE?

A: Yes. MAX1246ACEE+ is a direct functional equivalent with identical electrical performance, pin configuration, and package specifications. The primary differences are product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between MAX1246ACEE+ and MAX1246BCEE+?

A: Both parts are parametrically equivalent with identical electrical specifications, sampling rate, resolution, input configurations, and package type. Both are in active production and ROHS3 compliant. Selection between them is based on availability and inventory requirements.

Q: Are there any package or mounting differences between the substitute parts?

A: No. All three parts use the same 16-SSOP package with 0.154" width (3.90mm) and surface mount technology. PCB footprints are identical.

Q: Is the SPI interface protocol identical across all three parts?

A: Yes. The data interface, protocol timing, and communication specifications are identical across MAX1246ACEE, MAX1246ACEE+, and MAX1246BCEE+.

Q: What is the significance of the RoHS compliance difference?

A: MAX1246ACEE is RoHS non-compliant, while MAX1246ACEE+ and MAX1246BCEE+ are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the compliant substitutes are mandatory.

Q: Can both substitute parts handle the same supply voltage range?

A: Yes. All three parts operate with analog and digital supply voltages in the 2.7V ~ 3.6V range and support the same operating temperature range of 0°C ~ 70°C.
