TLV2370IDR Equivalent & Substitute Parts
Part Overview
The TLV2370IDR is a general purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This rail-to-rail amplifier is designed for low-power applications requiring single-circuit amplification across a wide supply voltage range of 2.7 V to 16 V. The device is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when original inventory is unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications permit operation with different performance characteristics within defined electrical parameters.

Substitute Part Grouping Explanation
Substitution of the TLV2370IDR is determined by the following critical parameters: single-circuit configuration, rail-to-rail output capability, supply voltage range compatibility (minimum 2.7 V, maximum 16 V), operating temperature range (-40°C to 125°C), and surface mount technology. Substitute parts must maintain these core electrical and mechanical characteristics to ensure functional equivalence in circuit applications.
The substitute parts identified fall into two primary categories based on amplifier topology and performance characteristics:
Category 1: Voltage Feedback Amplifiers (AD8027 Series) These parts feature voltage feedback topology with significantly higher slew rate (100 V/µs) and bandwidth (190 MHz) compared to the TLV2370IDR. They are available in both 8-SOIC and SOT-23-6 packages with multiple packaging options (Tube, Tape & Reel, Cut Tape & Digi-Reel). Supply voltage range is 2.7 V to 12 V, which is compatible with the TLV2370IDR's lower operating range but does not extend to the full 16 V maximum.
Category 2: General Purpose Amplifiers (AD8029 Series) These parts maintain general purpose amplifier classification with rail-to-rail output, matching the TLV2370IDR's functional category. They offer higher slew rate (63 V/µs) and bandwidth (125 MHz) with supply voltage range of 2.7 V to 12 V. Available packages include 8-SOIC and SC-70-6 with multiple packaging formats.
All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity rating, and active product status.

Engineering Selection Recommendations
For 8-SOIC Package Compatibility: The AD8027ARZ and AD8027ARZ-REEL variants maintain identical 8-SOIC packaging to the TLV2370IDR, enabling direct footprint compatibility on printed circuit boards. These voltage feedback amplifiers provide enhanced performance with 100 V/µs slew rate and 190 MHz bandwidth. However, the maximum supply voltage is limited to 12 V, requiring circuit design verification if the original application utilizes the full 16 V supply range of the TLV2370IDR.
The AD8029ARZ and AD8029ARZ-REEL variants also provide 8-SOIC packaging with general purpose amplifier classification matching the TLV2370IDR's functional category. These devices offer 63 V/µs slew rate and 125 MHz bandwidth with 12 V maximum supply voltage.
For Alternative Packaging Formats: The AD8027ARTZ-R2 and AD8027ARTZ-REEL7 variants are available in SOT-23-6 package, suitable for space-constrained applications or automated assembly processes requiring smaller form factors. The AD8029AKSZ-REEL and AD8029AKSZ-REEL7 variants are available in SC-70-6 package for miniaturized designs.
Compliance and Regulatory Considerations: All identified substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and active product status, ensuring compatibility with current manufacturing standards and supply chain reliability.
Frequently Asked Questions (FAQ)
Q: Can AD8027 series parts directly replace TLV2370IDR in all applications?
A: AD8027 series parts are electrically compatible for applications operating within the 2.7 V to 12 V supply range. If your circuit requires the full 16 V maximum supply voltage of the TLV2370IDR, AD8027 substitution is not suitable. The AD8027 offers superior performance characteristics (100 V/µs slew rate, 190 MHz bandwidth) compared to TLV2370IDR (2.1 V/µs, 3 MHz), making it suitable for higher-speed applications.
Q: What is the difference between AD8027ARZ and AD8027ARZ-REEL packaging?
A: Both variants use identical 8-SOIC package and electrical specifications. AD8027ARZ is supplied in Tube packaging for manual handling and lower-volume applications. AD8027ARZ-REEL is supplied in Tape & Reel format for automated pick-and-place assembly processes. Selection depends on manufacturing process requirements.
Q: Why does AD8029 series have higher output current capability than TLV2370IDR?
A: AD8029 series provides 170 mA output current per channel compared to TLV2370IDR's 16 mA. This enhanced output drive capability is a characteristic of the AD8029 design and does not prevent substitution; applications requiring only 16 mA output current will operate within the AD8029's specifications.
Q: Are SOT-23-6 package variants (AD8027ARTZ-R2) footprint compatible with 8-SOIC designs?
A: No. SOT-23-6 and 8-SOIC packages have different pin counts, spacing, and physical dimensions. SOT-23-6 variants require circuit board redesign and cannot be used as direct substitutes in existing 8-SOIC footprints. Use 8-SOIC package variants (AD8027ARZ, AD8029ARZ) for footprint compatibility.
Q: What is the significance of the -REEL7 suffix in part numbers?
A: The -REEL7 suffix indicates Digi-Reel packaging format, a specific tape and reel configuration. Parts with -REEL suffix use standard Tape & Reel format. Both formats contain identical components; selection depends on supplier inventory and manufacturing equipment compatibility.
Q: Can I use AD8029 series as a substitute if my application requires 3 MHz bandwidth?
A: Yes. AD8029 series provides 125 MHz bandwidth (-3dB), which exceeds the 3 MHz gain-bandwidth product of TLV2370IDR. Applications designed for 3 MHz operation will function correctly with AD8029 series, which offers additional bandwidth margin.
Q: What supply voltage range should I verify before substituting?
A: Verify that your circuit operates within 2.7 V to 12 V range for AD8027 and AD8029 series substitutes. If your design requires operation at voltages above 12 V up to the TLV2370IDR's maximum of 16 V, these substitutes are not suitable. The TLV2370IDR's extended 16 V maximum rating is not matched by the identified substitute parts.
