AD7730LBRU Equivalent & Substitute Parts

Part Overview

The AD7730LBRU is a 24-bit, single-channel analog front-end (AFE) integrated circuit manufactured by Analog Devices Inc., designed for precision data acquisition applications. It operates at 125 mW power consumption with dual supply voltages (5V analog, 2.7V–5.25V digital) and is housed in a 24-TSSOP surface-mount package.

The AD7730LBRU is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for legacy systems and new designs requiring this functional specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD7730LBRU is determined by strict equivalence across the following critical parameters:

• Resolution: 24-bit analog-to-digital conversion capability
• Channel Configuration: Single-channel input architecture
• Power Specification: 125 mW maximum power consumption
• Supply Voltages: 5V analog supply and 2.7V–5.25V digital supply compatibility
• Package Compatibility: 24-TSSOP surface-mount form factor with 0.173" (4.40mm) width
• Moisture Sensitivity: MSL 1 rating (unlimited floor life)

The AD7730LBRUZ qualifies as a direct substitute based on identical electrical specifications and package requirements. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The AD7730LBRUZ is the direct substitute for the AD7730LBRU. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility.

The AD7730LBRUZ is preferred for new designs and ongoing production due to its active product status. It carries ROHS3 compliance and REACH unaffected certification, meeting current regulatory requirements for electronic components in regulated markets.

The AD7730LBRU, classified as obsolete, should be replaced with the AD7730LBRUZ in legacy system redesigns and supply chain transitions. Inventory availability of the AD7730LBRUZ (3400 pcs) supports both immediate procurement and long-term supply security.

Frequently Asked Questions (FAQ)

Q: Can the AD7730LBRUZ directly replace the AD7730LBRU in existing designs?

A: Yes. The AD7730LBRUZ is electrically and mechanically identical to the AD7730LBRU. No circuit modifications, firmware changes, or PCB redesign are required. Both parts operate at 24-bit resolution, single-channel configuration, 125 mW power consumption, and use identical 24-TSSOP packaging.

Q: What is the difference between AD7730LBRU and AD7730LBRUZ?

A: The primary differences are product status and packaging format. The AD7730LBRU is obsolete; the AD7730LBRUZ is active. The AD7730LBRUZ is supplied in tube packaging and includes ROHS3 and REACH compliance certifications. Electrical specifications and package dimensions are identical.

Q: Are there any supply voltage or power consumption differences?

A: No. Both parts require 5V analog supply and 2.7V–5.25V digital supply. Both consume 125 mW maximum power. Substitution does not require power supply modifications.

Q: Is the 24-TSSOP package identical between both parts?

A: Yes. Both the AD7730LBRU and AD7730LBRUZ use the 24-TSSOP package with 0.173" (4.40mm) width. Pin assignments, spacing, and PCB footprint are identical. No layout changes are necessary.

Q: Does the AD7730LBRUZ meet current regulatory requirements?

A: Yes. The AD7730LBRUZ is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components in most regulated markets.
