ISL5761IAZ Equivalent & Substitute Parts

Part Overview

The ISL5761IAZ is a 10-bit digital-to-analog converter (DAC) manufactured by Renesas Electronics Corporation, housed in a 28-TSSOP surface mount package. This component features current-mode unbuffered output with differential capability, supporting both external and internal reference configurations. The device operates across analog and digital supply voltages of 2.7V to 3.6V with an operating temperature range of -40°C to 85°C.

The ISL5761IAZ is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications utilizing this DAC architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISL5761IAZ is determined by the following core parameters:

• Resolution: 10-bit conversion capability
• Output Architecture: Current-mode unbuffered with differential output
• Data Interface: Parallel input configuration
• Reference Configuration: Support for both external and internal references
• Package Compatibility: 28-TSSOP surface mount form factor
• Supply Voltage Range: Minimum coverage of 2.7V to 3.6V for both analog and digital supplies
• Temperature Range: -40°C to 85°C operating window
• Compliance: ROHS3 compliance and EAR99 classification

The DAC900E from Texas Instruments meets these substitution criteria. Both devices share identical resolution, output type, data interface, reference flexibility, package form factor, and temperature operating range. The DAC900E maintains ROHS3 compliance and EAR99 classification, ensuring regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The DAC900E qualifies as a direct substitute for the ISL5761IAZ based on functional equivalence and regulatory compliance. Both devices maintain ROHS3 compliance and EAR99 classification, ensuring consistency with supply chain and export requirements.

The DAC900E carries active product status from Texas Instruments, providing assured long-term availability and supply chain stability compared to the obsolete ISL5761IAZ. The expanded supply voltage range (2.7V to 5.5V) of the DAC900E provides design flexibility for applications operating within the ISL5761IAZ's original 2.7V to 3.6V specification window.

The INL/DNL specifications of the DAC900E (±0.5, ±0.3 LSB) are less stringent than the ISL5761IAZ (±0.1, ±0.1 LSB). Applications requiring the tighter linearity performance of the original device should evaluate this difference against system-level accuracy requirements.

Frequently Asked Questions (FAQ)

Q: Can the DAC900E directly replace the ISL5761IAZ in existing designs?

A: Yes, for applications operating within the 2.7V to 3.6V supply voltage range. Both devices share identical 10-bit resolution, current-mode unbuffered output architecture, differential output capability, parallel data interface, reference configuration flexibility, 28-TSSOP package form factor, and -40°C to 85°C operating temperature range. Pin-level compatibility and functional equivalence are established.

Q: What are the key differences between these devices?

A: The primary differences are product status (ISL5761IAZ is obsolete; DAC900E is active), supply voltage range (DAC900E extends to 5.5V), linearity specifications (DAC900E has ±0.5/±0.3 LSB INL/DNL versus ±0.1/±0.1 LSB), and settling time documentation (DAC900E specifies 30ns typical). The DAC900E also features a lower moisture sensitivity level (MSL 2 versus MSL 3).

Q: Are there any package or mounting considerations?

A: Both devices use the 28-TSSOP surface mount package with identical physical dimensions (0.173" width, 4.40mm). No PCB layout modifications are required for package compatibility.

Q: Do both devices support the same reference configurations?

A: Yes. Both the ISL5761IAZ and DAC900E support external and internal reference types, providing identical flexibility for reference circuit design.

Q: What compliance certifications apply to the DAC900E?

A: The DAC900E maintains ROHS3 compliance and EAR99 classification, matching the regulatory status of the ISL5761IAZ.
