Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX9693EEE is determined by the following critical parameters that must align across candidate parts:

Core Functional Requirements:

• Dual comparator architecture with integrated latch functionality
• Complementary output configuration
• 16-pin QSOP package with identical 0.154" (3.90mm) width
• Surface mount technology compatibility
• Operating temperature range: -40°C to 85°C minimum
• ECL or PECL output standard compatibility

Electrical Performance Criteria:

• Input offset voltage specification
• Input bias current specification
• Output current capability
• Propagation delay performance
• Common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR)

The identified substitute parts ADCMP561BRQZ and ADCMP563BRQZ meet these core requirements while offering active product status and improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both ADCMP561BRQZ and ADCMP563BRQZ are active products manufactured by Analog Devices Inc., providing long-term availability and supply chain stability compared to the obsolete MAX9693EEE. Both substitute parts maintain identical package geometry (16-SSOP), surface mount compatibility, and operating temperature specifications.

The ADCMP561BRQZ features PECL output architecture with open-emitter configuration, while the ADCMP563BRQZ provides ECL output with open-emitter configuration. Both deliver superior electrical performance including reduced input offset voltage (2mV versus 6.5mV), lower input bias current (3µA versus 20µA), and faster propagation delay (0.83ns versus 1.8ns).

Both substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing and environmental standards. The dual sourcing option between ADCMP561BRQZ and ADCMP563BRQZ provides design flexibility based on specific output standard requirements within the application circuit.

Frequently Asked Questions (FAQ)

Q: Why is substitution necessary for the MAX9693EEE? A: The MAX9693EEE is classified as obsolete, making new inventory procurement difficult. Active substitute parts ensure continued design support and component availability.

Q: Are the substitute parts pin-compatible with the MAX9693EEE? A: Both ADCMP561BRQZ and ADCMP563BRQZ use the identical 16-SSOP package with 0.154" (3.90mm) width, providing mechanical and electrical pin compatibility for direct board-level substitution.

Q: What is the difference between ADCMP561BRQZ and ADCMP563BRQZ? A: The primary difference is output standard: ADCMP561BRQZ implements PECL (Positive ECL) output, while ADCMP563BRQZ implements ECL output. Both share identical electrical performance specifications and package configuration.

Q: Do the substitute parts meet the same compliance standards? A: Yes. Both ADCMP561BRQZ and ADCMP563BRQZ are ROHS3 compliant with MSL Level 1 rating, matching the MAX9693EEE compliance profile.

Q: How do the electrical specifications compare? A: The substitute parts offer improved performance: input offset voltage reduced from 6.5mV to 2mV, input bias current reduced from 20µA to 3µA, and propagation delay improved from 1.8ns to 0.83ns. CMRR remains at 80dB while PSRR improves from 60dB to 85dB.

Q: What is the operating temperature range for the substitute parts? A: Both ADCMP561BRQZ and ADCMP563BRQZ operate across -40°C to 85°C, matching the MAX9693EEE specification.

Q: Are there inventory considerations for these substitute parts? A: ADCMP561BRQZ has 1961 pieces in stock and ADCMP563BRQZ has 1234 pieces in stock, compared to 780 pieces of the obsolete MAX9693EEE, providing improved availability.
