THS4504DR Equivalent & Substitute Parts

Part Overview

The THS4504DR is an active differential amplifier integrated circuit manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device functions as a single-channel differential amplifier with high-speed performance characteristics, including a slew rate of 1800V/µs and gain bandwidth product of 210 MHz. The THS4504DR maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent functional performance is required due to inventory constraints, design optimization, or application-specific requirements within the linear amplifier category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the THS4504DR is determined by compatibility across the following critical parameters: package type (8-SOIC surface mount), number of circuits (single channel), operating temperature range (-40°C to 85°C), supply voltage compatibility, and regulatory compliance (RoHS3, REACH Unaffected, EAR99 classification). The substitute parts identified—AD8031ARZ, AD8031ARZ-REEL7, and LT6200IS8#PBF—share identical package geometry, single-circuit configuration, and operating temperature specifications. All substitute parts maintain the same regulatory and environmental compliance status as the primary device. Substitution is valid when the application requirements permit operation within the electrical parameter ranges of the selected substitute, particularly regarding slew rate, bandwidth, input bias current, and supply voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and full RoHS3 compliance, ensuring regulatory continuity with the THS4504DR. The AD8031ARZ and AD8031ARZ-REEL7 are functionally identical devices differentiated only by packaging format (Tube versus Cut Tape & Digi-Reel). Selection between these two Analog Devices options depends on procurement and assembly workflow requirements. The LT6200IS8#PBF represents an alternative from the same manufacturer with comparable performance characteristics. Component selection should be based on application-specific electrical requirements, particularly where slew rate, bandwidth, and supply voltage specifications must be verified against circuit design parameters. All substitute parts are surface mount devices in 8-SOIC packages with identical footprints, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the AD8031ARZ directly replace the THS4504DR in existing designs?

A: Direct substitution is possible at the package level, as both devices use identical 8-SOIC surface mount packages. However, electrical parameter differences must be evaluated. The AD8031ARZ operates with lower slew rate (35V/µs versus 1800V/µs) and reduced bandwidth (80 MHz versus 260 MHz), which may impact high-frequency applications. Supply voltage compatibility exists within the overlapping range of 4.5V to 12V.

Q: What is the difference between AD8031ARZ and AD8031ARZ-REEL7?

A: Both parts are electrically identical with identical electrical specifications. The difference is packaging format: AD8031ARZ is supplied in Tube packaging, while AD8031ARZ-REEL7 is supplied in Cut Tape & Digi-Reel format. Selection depends on assembly line requirements and inventory management practices.

Q: Is the LT6200IS8#PBF suitable for high-speed differential applications?

A: The LT6200IS8#PBF is classified as a general-purpose amplifier with rail-to-rail output, offering a slew rate of 50V/µs and gain bandwidth product of 165 MHz. These specifications are lower than the THS4504DR. Suitability depends on specific application bandwidth and slew rate requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The THS4504DR and all identified substitute parts (AD8031ARZ, AD8031ARZ-REEL7, LT6200IS8#PBF) are RoHS3 compliant with REACH Unaffected status and EAR99 classification.

Q: What supply voltage range is compatible across all parts?

A: The overlapping supply voltage range compatible with all parts is 4.5V to 12V. The THS4504DR supports up to 15V, while the substitute parts maximum is 12V. Applications requiring supply voltages above 12V cannot use the identified substitutes.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. The THS4504DR and all substitute parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used interchangeably in production?

A: Interchangeability is limited to applications where electrical parameter differences do not affect circuit performance. Formal design verification is required when substituting between parts with different amplifier types (differential versus voltage feedback versus general purpose) or significantly different performance specifications.
