DDC264CZAW Equivalent & Substitute Parts

Part Overview

The DDC264CZAW is a 20-bit analog-to-digital converter manufactured by Texas Instruments, designed for high-resolution data acquisition applications. This device features 64 single-ended inputs with 32 sigma-delta converters, operating at a 6 kHz sampling rate per channel. The part is actively produced and widely used in industrial measurement, instrumentation, and precision signal processing systems where simultaneous sampling of multiple analog channels is required. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and procurement optimization when the primary part number becomes unavailable or when alternative sourcing is necessary.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DDC264CZAW are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain identical:

• Resolution: 20-bit conversion capability
• Input configuration: 64 single-ended inputs with 32 sigma-delta converters
• Sampling performance: 6 kHz sampling rate per channel
• Signal interface: SPI data interface
• Power supply requirements: 5V analog supply and 2.7V to 5.25V digital supply
• Package specification: 100-NFBGA (9x9) form factor
• Simultaneous sampling capability
• Operating temperature range: 0°C to 70°C
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The DDC264CKZAW meets all these criteria and is classified as a parametric equivalent. Both parts share the same base product number (DDC264) and are manufactured by Texas Instruments under identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations
