THS4500IDRG4 Equivalent & Substitute Parts

Part Overview

The THS4500IDRG4 is a differential amplifier integrated circuit manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device is classified as a linear amplifier with a single differential circuit configuration and differential output type. The THS4500IDRG4 is currently listed as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity. Active alternatives with identical or compatible electrical and mechanical specifications are available from Texas Instruments and Analog Devices Inc./Maxim Integrated.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete THS4500IDRG4 is determined by strict equivalence across electrical performance parameters and mechanical compatibility. The primary substitution criteria are:

Electrical Equivalence Parameters:

• Amplifier Type: Differential
• Number of Circuits: 1
• Output Type: Differential
• Slew Rate: 2800 V/µs
• Gain Bandwidth Product: 300 MHz
• -3dB Bandwidth: 370 MHz
• Current - Input Bias: 4 µA
• Voltage - Input Offset: 4 mV
• Current - Supply: 23 mA
• Voltage - Supply Span: 4.5 V to 15 V
• Operating Temperature Range: -40°C to 85°C

Mechanical Compatibility Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 8-SOIC

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are grouped into two categories: direct electrical equivalents from Texas Instruments (THS4501IDR and THS4500ID) and alternative amplifier topologies from other manufacturers (MAX4215ESA+). The THS4501IDR and THS4500ID maintain identical electrical specifications and package compatibility. The MAX4215ESA+ represents a functional alternative with different amplifier topology (buffer vs. differential) and modified electrical characteristics, suitable only for applications where buffer amplification meets design requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents):

The THS4501IDR and THS4500ID are direct electrical and mechanical equivalents of the THS4500IDRG4. Both devices are manufactured by Texas Instruments and maintain identical specifications across all critical parameters: differential amplifier topology, 2800 V/µs slew rate, 300 MHz gain bandwidth product, 370 MHz -3dB bandwidth, and 8-SOIC surface mount packaging. Both substitute parts carry Active product status, ensuring long-term availability and manufacturing support. The THS4501IDR is supplied in Tape & Reel packaging, while the THS4500ID is supplied in Tube packaging. Selection between these two should be based on procurement and assembly requirements. Both are ROHS3 compliant with MSL 1 rating, matching the compliance profile of the main part.

Secondary Substitute (Functional Alternative):

The MAX4215ESA+ from Analog Devices Inc./Maxim Integrated represents a functional alternative suitable only for applications where buffer amplifier topology is acceptable. This device differs significantly in amplifier type (buffer vs. differential), output type (rail-to-rail vs. differential), slew rate (600 V/µs vs. 2800 V/µs), and -3dB bandwidth (230 MHz vs. 370 MHz). The MAX4215ESA+ exhibits lower supply current (5.5 mA vs. 23 mA) and operates across a narrower supply voltage range (3.15 V to 11 V vs. 4.5 V to 15 V). This substitute is appropriate only for designs where differential output is not required and lower bandwidth performance is acceptable. The MAX4215ESA+ maintains identical 8-SOIC package compatibility, operating temperature range, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the THS4501IDR directly replace the THS4500IDRG4 in existing designs?

A: Yes. The THS4501IDR is a direct electrical and mechanical equivalent. All critical parameters—amplifier type, output type, slew rate, bandwidth, supply current, and supply voltage range—are identical. The 8-SOIC package dimensions and surface mount configuration are unchanged. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. original packaging).

Q: What is the difference between THS4501IDR and THS4500ID?

A: Both devices are electrically identical to the THS4500IDRG4. The difference is packaging format: THS4501IDR is supplied in Tape & Reel (TR) format, while THS4500ID is supplied in Tube format. Selection depends on assembly line requirements and procurement preferences. Both are Active products with identical electrical specifications.

Q: Is the MAX4215ESA+ a suitable replacement for the THS4500IDRG4?

A: The MAX4215ESA+ is not a direct replacement. While it shares the same 8-SOIC package and operating temperature range, it is a buffer amplifier rather than a differential amplifier. The MAX4215ESA+ has lower slew rate (600 V/µs vs. 2800 V/µs), lower bandwidth (230 MHz vs. 370 MHz), and lower supply current (5.5 mA vs. 23 mA). Use the MAX4215ESA+ only if your application requires buffer amplification and can tolerate reduced bandwidth and slew rate performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The THS4501IDR, THS4500ID, and MAX4215ESA+ are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the THS4500IDRG4.

Q: What is the inventory status of substitute parts?

A: THS4501IDR has 4093 pieces in stock, THS4500ID has 1258 pieces in stock, and MAX4215ESA+ has 1049 pieces in stock. All substitute parts are available as new original components.

Q: Can I use the THS4500ID in high-volume production?

A: Yes. The THS4500ID is an Active product from Texas Instruments with robust inventory levels (1258 pieces) and full manufacturing support. It is suitable for production applications requiring long-term component availability and supply chain stability.

Q: What are the key electrical differences between the THS4500IDRG4 and MAX4215ESA+?

A: The primary differences are amplifier topology (differential vs. buffer), output type (differential vs. rail-to-rail), slew rate (2800 V/µs vs. 600 V/µs), -3dB bandwidth (370 MHz vs. 230 MHz), supply current (23 mA vs. 5.5 mA), and supply voltage range (4.5–15 V vs. 3.15–11 V). These differences make the MAX4215ESA+ unsuitable for applications requiring differential amplification or high-speed signal processing.

Q: Are there any thermal or reliability differences between substitute parts?

A: All substitute parts operate across the identical temperature range (-40°C to 85°C) and share the same MSL 1 rating. No thermal or reliability differences are specified in the provided parameters.
