OPA211IDR Equivalent & Substitute Parts

Part Overview

The OPA211IDR is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. This rail-to-rail output amplifier is designed for applications requiring moderate bandwidth and low input offset voltage. The device is actively produced and maintains full RoHS3 compliance with REACH unaffected status.

Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical constraints of the application. The OPA211IDR operates across a wide supply voltage range (4.5V to 36V) and temperature range (-40°C to 125°C), making substitution analysis critical for applications with specific performance or availability requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPA211IDR is evaluated based on functional equivalence within the following critical parameters:

Mechanical Compatibility:

• Package type: 8-SOIC surface-mount form factor
• Pin count and pitch: 8-pin configuration with 0.154" (3.90mm) width

Electrical Compatibility:

• Output configuration: Rail-to-rail output capability
• Supply voltage range: Minimum 4.5V to maximum 36V operation
• Amplifier classification: General-purpose single-circuit topology
• Thermal operating range: -40°C to 125°C

Performance Characteristics:

• Slew rate: 27 V/µs
• Gain bandwidth product: 80 MHz
• Input bias current: 60 nA
• Input offset voltage: 30 µV
• Output current capability: 30 mA per channel
• Supply current: 3.6 mA

The LT6013CS8#PBF from Analog Devices Inc. is identified as a manufacturer-recommended substitute. However, this substitute exhibits significant deviations in performance specifications that must be evaluated against application requirements.

Engineering Selection Recommendations

OPA211IDR (Primary Selection)

The OPA211IDR is the specified component and remains the primary selection. It is actively produced with full product status confirmation. The device carries ROHS3 compliance and REACH unaffected designation, meeting regulatory requirements for industrial and commercial applications. Current inventory of 1252 pieces supports immediate procurement.

LT6013CS8#PBF (Manufacturer-Recommended Substitute)

The LT6013CS8#PBF is designated as a manufacturer-recommended substitute and maintains mechanical compatibility through identical 8-SOIC packaging. Both devices are actively produced with equivalent regulatory compliance (ROHS3, REACH unaffected).

Critical Specification Deviations:

The LT6013CS8#PBF exhibits the following performance differences from the OPA211IDR:

• Slew rate reduced to 0.2 V/µs (135× slower)
• Gain bandwidth product reduced to 1.4 MHz (57× lower)
• Operating temperature range limited to 0°C to 70°C (narrower than -40°C to 125°C)
• Output current capability reduced to 20 mA (33% lower than 30 mA)
• Supply current reduced to 0.2 mA (94% lower than 3.6 mA)
• Minimum supply voltage reduced to 2.7 V (lower than 4.5 V requirement)

These deviations indicate the LT6013CS8#PBF is suitable only for applications where the reduced bandwidth, slew rate, and temperature range do not conflict with system requirements. Applications requiring the full 80 MHz bandwidth, 27 V/µs slew rate, or extended temperature operation must retain the OPA211IDR.

Frequently Asked Questions (FAQ)

Q: Can the LT6013CS8#PBF directly replace the OPA211IDR in all applications?

A: No. While both devices share the same 8-SOIC package and rail-to-rail output configuration, the LT6013CS8#PBF has significantly reduced bandwidth (1.4 MHz vs. 80 MHz), slew rate (0.2 V/µs vs. 27 V/µs), and a narrower operating temperature range (0°C to 70°C vs. -40°C to 125°C). Substitution is valid only when application requirements fall within the LT6013CS8#PBF specifications.

Q: What is the primary mechanical compatibility factor?

A: Both the OPA211IDR and LT6013CS8#PBF use identical 8-SOIC surface-mount packaging with 0.154" (3.90mm) width. This ensures pin-for-pin compatibility at the PCB layout level. Packaging differences exist only in supplier format (Cut Tape/Digi-Reel for OPA211IDR vs. Tube for LT6013CS8#PBF).

Q: Are there temperature range restrictions with the substitute?

A: Yes. The LT6013CS8#PBF operates from 0°C to 70°C, while the OPA211IDR operates from -40°C to 125°C. Applications requiring operation below 0°C or above 70°C must use the OPA211IDR.

Q: How do the bandwidth specifications compare?

A: The OPA211IDR provides 80 MHz gain bandwidth product with 27 V/µs slew rate. The LT6013CS8#PBF provides 1.4 MHz gain bandwidth product with 0.2 V/µs slew rate. High-frequency applications and fast-settling requirements necessitate the OPA211IDR.

Q: What are the supply current implications?

A: The OPA211IDR draws 3.6 mA supply current, while the LT6013CS8#PBF draws 0.2 mA. The substitute offers significant power savings for battery-powered or low-power applications, provided bandwidth and temperature requirements are met.

Q: Are both devices RoHS and REACH compliant?

A: Yes. Both the OPA211IDR and LT6013CS8#PBF are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory standards for commercial and industrial deployment.

Q: What is the output current capability difference?

A: The OPA211IDR provides 30 mA output current per channel, while the LT6013CS8#PBF provides 20 mA. Applications requiring higher output drive capability must use the OPA211IDR.
