• Data Interface: SPI protocol
• Architecture: SAR with MUX-S/H-ADC configuration
• Supply Voltage Range: 2.7V ~ 5.25V (both analog and digital)
• Operating Temperature: 0°C ~ 70°C
• Package: 16-SSOP (0.154", 3.90mm Width)
• Mounting: Surface Mount

The substitute parts identified below maintain identical electrical specifications and package form factor, ensuring direct functional replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The MAX1248BCEE is classified as obsolete. For new designs and ongoing system support, the MAX1248BCEE+ and MAX1248ACEE+ are direct functional equivalents with identical electrical and mechanical specifications.

MAX1248BCEE+ is the direct successor to the MAX1248BCEE, maintaining the same part number base with active product status. This part is ROHS3 compliant and supplied in tube packaging, making it suitable for production environments.

MAX1248ACEE+ is a parametric equivalent offering identical electrical performance and package specifications. This part is also ROHS3 compliant and supplied in tube packaging.

Both substitute parts are manufactured by the same supplier and provide full compatibility with existing MAX1248BCEE designs without requiring circuit modifications.

Frequently Asked Questions (FAQ)
