MAX508ACWP Equivalent & Substitute Parts

Part Overview

The MAX508ACWP is a 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring voltage output conversion. This component features an internal reference, parallel data interface, and R-2R architecture in a 20-SOIC surface mount package.

The MAX508ACWP is classified as obsolete. Identifying equivalent and substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX508ACWP is determined by strict equivalence across the following critical parameters:

• Resolution: 12 bits
• Number of D/A Converters: 1
• Output Type: Voltage - Buffered
• Data Interface: Parallel
• Reference Type: Internal
• Voltage Supply Ranges: ±11.4V ~ 15.75V (analog), 11.4V ~ 15.75V (digital)
• INL/DNL Performance: ±0.75 (Max), ±1 (Max)
• Architecture: R-2R
• Operating Temperature Range: 0°C ~ 70°C
• Package: 20-SOIC surface mount

The MAX508ACWP+ meets all electrical and mechanical substitution criteria and is classified as an active product, making it suitable for direct replacement in applications currently using the obsolete MAX508ACWP.

Parameter Comparison

Engineering Selection Recommendations

The MAX508ACWP+ is the direct substitute for the MAX508ACWP. Both components share identical electrical specifications and mechanical packaging. The primary distinction is product status and regulatory compliance: the MAX508ACWP+ is an active product with ROHS3 compliance, whereas the MAX508ACWP is obsolete and RoHS non-compliant.

For new designs or system updates, the MAX508ACWP+ is the appropriate selection. For legacy system maintenance requiring exact form-fit-function replacement, the MAX508ACWP+ provides electrical and mechanical equivalence with the added benefit of current manufacturing status and improved regulatory compliance.
