SA5534PS Equivalent & Substitute Parts Reference

Part Overview

The SA5534PS is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SO surface mount package. This device is classified as obsolete, which necessitates identification of active equivalent and substitute components for ongoing design support and procurement. The SA5534PS operates across a supply voltage range of 10V to 30V with a slew rate of 13V/µs and gain bandwidth product of 10 MHz, making it suitable for general-purpose amplification applications requiring moderate bandwidth performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SA5534PS is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier Type: General Purpose (single circuit configuration)
• Supply Voltage Range: Substitute must operate within or exceed the 10V to 30V span
• Input Offset Voltage: 500 µV (matching specification)
• Operating Temperature Range: -40°C to 85°C minimum
• Output Current Capability: Minimum 32 mA per channel

Mechanical Compatibility Criteria:

• Surface Mount package configuration
• 8-pin SOIC package footprint
• Pin-compatible layout

Compliance Requirements:

• ROHS3 Compliant
• Moisture Sensitivity Level 1 (Unlimited)

The substitute parts AD847ARZ and AD847ARZ-REEL meet these criteria. Both are manufactured by Analog Devices Inc. and are classified as active products. These substitutes provide enhanced electrical performance (higher slew rate of 300V/µs and gain bandwidth product of 50 MHz) while maintaining backward compatibility with the SA5534PS electrical specifications and package requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: AD847ARZ and AD847ARZ-REEL

Both AD847ARZ variants are classified as active products with full ROHS3 compliance and unlimited moisture sensitivity rating, matching the SA5534PS compliance profile. The electrical parameters of the AD847 series exceed the minimum requirements of the SA5534PS across all critical specifications:

• Supply voltage range is extended (9V to 36V versus 10V to 30V)
• Slew rate performance is significantly enhanced (300V/µs versus 13V/µs)
• Gain bandwidth product is increased (50 MHz versus 10 MHz)
• Input offset voltage specification is maintained at 500 µV
• Operating temperature range is identical (-40°C to 85°C)

Packaging Consideration:

The AD847ARZ is supplied in Tube packaging, while the AD847ARZ-REEL is supplied in Reel packaging. Both use the 8-SOIC package format with identical electrical specifications. The physical package width differs (0.154" versus 0.209"), which may require PCB layout evaluation for existing designs. Pin configuration and functional compatibility remain unchanged.

Both substitutes are available in quantities suitable for production deployment.

Frequently Asked Questions (FAQ)

Q1: Can AD847ARZ directly replace SA5534PS in existing designs?

A: The AD847ARZ and AD847ARZ-REEL are electrically compatible with the SA5534PS and share identical pin configuration in the 8-SOIC package. However, the physical package width differs (0.154" versus 0.209"), which may affect PCB layout compatibility. Electrical performance of the AD847 series exceeds SA5534PS specifications across all parameters, making it suitable for direct substitution in applications where the PCB footprint accommodates the narrower package width.

Q2: What are the key electrical advantages of AD847ARZ over SA5534PS?

A: The AD847ARZ provides superior performance in three critical areas: slew rate (300V/µs versus 13V/µs), gain bandwidth product (50 MHz versus 10 MHz), and extended supply voltage range (9V to 36V versus 10V to 30V). These enhancements enable the AD847 to support higher-frequency applications and provide greater design margin in power supply specifications.

Q3: Are there packaging differences between AD847ARZ and AD847ARZ-REEL?

A: Both parts are identical in electrical specifications and pin configuration. The primary difference is packaging format: AD847ARZ is supplied in Tube packaging, while AD847ARZ-REEL is supplied in Reel packaging. Selection depends on assembly process requirements and inventory management preferences.

Q4: Do the substitute parts meet the same compliance requirements as SA5534PS?

A: Yes. Both AD847ARZ and AD847ARZ-REEL are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the SA5534PS compliance profile. REACH status is unaffected for all three parts, and ECCN classification is identical (EAR99).

Q5: What is the operating temperature range for substitute parts?

A: Both AD847ARZ variants operate across the identical temperature range as the SA5534PS: -40°C to 85°C. This ensures thermal compatibility in applications with the same environmental specifications.

Q6: How do input bias current specifications compare?

A: The SA5534PS specifies 500 nA input bias current, while the AD847ARZ specifies 3.3 µA. This represents a higher input bias current in the substitute part. Applications with high-impedance input sources may require circuit design evaluation to ensure acceptable performance with the increased bias current specification.
