Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADC0804S040TS/C1'1 is determined by the following core electrical and mechanical parameters:

• 8-bit resolution
• 40M sampling rate
• Single-ended input configuration
• Parallel data interface
• External reference type
• 5V analog and digital supply voltages
• -40°C to 85°C operating temperature range
• Surface mount technology

The TLC5540IPW from Texas Instruments meets all critical electrical specifications required for functional equivalence. While the package differs (24-TSSOP versus 28-SSOP), both are surface-mount packages suitable for PCB integration. The substitute maintains identical bit resolution, sampling rate, input configuration, data interface, reference type, and supply voltage requirements.

Parameter Comparison

Engineering Selection Recommendations

The TLC5540IPW is a direct functional equivalent for the ADC0804S040TS/C1'1 based on electrical parameter alignment. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete ADC0804S040TS/C1'1.

Both components maintain ROHS3 compliance and are suitable for applications requiring 8-bit analog to digital conversion at 40M sampling rates with single-ended inputs and external reference configuration. The package transition from 28-SSOP to 24-TSSOP requires PCB layout modification but does not affect electrical functionality.

Frequently Asked Questions (FAQ)

Q: Can the TLC5540IPW directly replace the ADC0804S040TS/C1'1 without circuit modifications?

A: The TLC5540IPW provides electrical equivalence for all core ADC functions. However, the package change from 28-SSOP to 24-TSSOP requires PCB footprint redesign. Pin-to-pin correspondence must be verified during layout migration.

Q: What is the primary reason for seeking a substitute for the ADC0804S040TS/C1'1?

A: The ADC0804S040TS/C1'1 is classified as obsolete. The TLC5540IPW is an active product with guaranteed availability and manufacturing support.

Q: Are there compliance differences between these parts?

A: Both components are ROHS3 compliant and carry identical REACH and ECCN classifications, ensuring regulatory equivalence for industrial and commercial applications.

Q: Does the package size difference affect performance?

A: Package size does not affect electrical performance. The 24-TSSOP package is physically smaller than the 28-SSOP, which may provide space advantages in compact designs but requires PCB layout reconfiguration.

Q: What parameters must remain constant for substitution validity?

A: Bit resolution (8-bit), sampling rate (40M), input configuration (single-ended), data interface (parallel), reference type (external), and supply voltages (5V analog and digital) must all remain unchanged for functional equivalence.
