THS4012IDRG4 Equivalent & Substitute Parts

Part Overview

The THS4012IDRG4 is a voltage feedback amplifier manufactured by Texas Instruments, configured as a dual-circuit operational amplifier in an 8-SOIC surface mount package. This device is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and production continuity. The THS4012IDRG4 delivers high-speed performance with a 310 V/µs slew rate and 290 MHz gain bandwidth product, suitable for applications requiring fast signal conditioning and amplification across a wide supply voltage range of 9 V to 32 V.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the THS4012IDRG4 is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 8-SOIC surface mount configuration
• Physical dimensions: 0.154" width, 3.90mm width specification
• Mounting method: Surface mount technology

Electrical Compatibility:

• Dual-circuit configuration (2 circuits per package)
• Operating temperature range: -40°C to 85°C minimum requirement
• Supply voltage range: Minimum 9 V to maximum 32 V capability
• Output current per channel: Minimum 110 mA capability

Regulatory & Compliance:

• RoHS3 compliance requirement
• MSL rating: 1 (Unlimited)
• REACH unaffected status

The LT1469 series from Analog Devices Inc. satisfies the mechanical package requirements and regulatory compliance standards. However, the LT1469 series exhibits reduced electrical performance specifications compared to the THS4012IDRG4, including lower slew rate (22 V/µs versus 310 V/µs), lower gain bandwidth product (90 MHz versus 290 MHz), and reduced supply voltage range (5 V to 9 V maximum versus 9 V to 32 V). Substitution is valid only for applications where the reduced performance parameters are acceptable.

Engineering Selection Recommendations

Product Status Consideration: The THS4012IDRG4 is classified as obsolete. All substitute parts from the LT1469 series are active products with ongoing manufacturer support and availability. Selection of an active substitute ensures long-term supply chain continuity and access to technical documentation.

Temperature Range Matching: For applications requiring the full -40°C to 85°C operating temperature range of the original THS4012IDRG4, the LT1469IS8#PBF and LT1469IS8#TRPBF variants are the appropriate selections. The LT1469CS8 variants operate only from 0°C to 70°C and are unsuitable for extended temperature applications.

Packaging Format Selection:

• LT1469CS8: Tube packaging for manual handling and small-quantity applications
• LT1469CS8#PBF: Tube packaging with lead-free plating
• LT1469CS8#TRPBF: Tape & Reel format with lead-free plating for automated assembly
• LT1469IS8#PBF: Tube packaging with extended temperature range and lead-free plating
• LT1469IS8#TRPBF: Tape & Reel format with extended temperature range and lead-free plating

Compliance Status: All substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) rating, and REACH unaffected status, matching the regulatory requirements of the original device.

Frequently Asked Questions (FAQ)

Q: Can the LT1469 series directly replace the THS4012IDRG4 in all applications?

A: Direct replacement is limited by electrical performance differences. The LT1469 series exhibits significantly lower slew rate (22 V/µs versus 310 V/µs) and lower gain bandwidth product (90 MHz versus 290 MHz). Substitution is valid only for applications where these reduced performance specifications are acceptable. Additionally, the LT1469 series maximum supply voltage is 9 V, compared to 32 V for the THS4012IDRG4, restricting use in high-voltage applications.

Q: What is the difference between LT1469CS8 and LT1469IS8 variants?

A: The primary difference is operating temperature range. LT1469CS8 variants operate from 0°C to 70°C, while LT1469IS8 variants operate from -40°C to 85°C. For applications requiring the full extended temperature range of the original THS4012IDRG4, the LT1469IS8 variants must be selected.

Q: What packaging options are available for the LT1469 substitute?

A: The LT1469 is available in three packaging configurations: standard tube (LT1469CS8 or LT1469IS8), tube with lead-free plating (#PBF suffix), and Tape & Reel with lead-free plating (#TRPBF suffix). Tube packaging is suitable for manual assembly and small quantities. Tape & Reel format is required for automated pick-and-place assembly operations.

Q: Are all LT1469 variants RoHS3 compliant?

A: Yes, all LT1469 variants listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status, matching the compliance profile of the original THS4012IDRG4.

Q: What supply voltage range does the LT1469 support?

A: The LT1469 series supports a supply voltage range of 5 V to 9 V maximum. This is narrower than the THS4012IDRG4 range of 9 V to 32 V. Applications requiring supply voltages above 9 V cannot use the LT1469 as a substitute.

Q: How does the output current capability compare?

A: The THS4012IDRG4 provides 110 mA output current per channel, while the LT1469 series provides 22 mA per channel. Applications requiring higher output current must evaluate alternative substitutes or implement external buffering stages.
