TL5580AIPWR Equivalent & Substitute Parts

Part Overview

The TL5580AIPWR is a general-purpose operational amplifier manufactured by Texas Instruments, configured as a dual-circuit (2 circuit) device in an 8-TSSOP surface mount package. This component is classified as Last Time Buy, indicating discontinued production with limited inventory availability. The TL5580AIPWR operates across a wide supply voltage range of 4V to 32V and is suitable for general-purpose amplification applications requiring moderate bandwidth and low input bias current characteristics. Due to its Last Time Buy status, identifying functionally equivalent substitute components is essential for design continuity and long-term supply chain planning.

Substitute Part Grouping Explanation

Substitute components for the TL5580AIPWR are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is structured around the following parameters:

Mechanical Compatibility: All substitute parts must use the 8-TSSOP surface mount package with identical pin configuration and footprint dimensions (0.173", 4.40mm Width).

Electrical Compatibility: Substitute parts must support dual-circuit (2 circuit) configuration and operate within overlapping supply voltage ranges. The TL5580AIPWR operates from 4V to 32V; substitute parts must accommodate this range or provide extended coverage.

Functional Classification: The TL5580AIPWR is classified as a general-purpose amplifier. Substitute parts may include alternative amplifier topologies (such as J-FET input stages) provided they maintain dual-circuit configuration and surface mount 8-TSSOP packaging.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and MSL Level 1 rating to ensure environmental and handling compatibility.

The substitute parts identified are grouped into two categories:

Direct Manufacturer Equivalent (TL5580IPWR): Identical electrical specifications and amplifier type, differing only in product status (Active vs. Last Time Buy).
Functional Alternatives (TL082CPT, TL082IPT): Different amplifier topology (J-FET input) with modified electrical characteristics but identical package and dual-circuit configuration.

Engineering Selection Recommendations

TL5580IPWR (Primary Substitute): This component is the direct manufacturer equivalent of the TL5580AIPWR, manufactured by Texas Instruments with identical electrical specifications and performance characteristics. The TL5580IPWR maintains Active product status with significantly higher inventory availability (4100 pcs vs. 914 pcs). This substitute is recommended as the primary replacement for new designs and ongoing production due to supply continuity and specification equivalence. Both components share identical operating temperature range (-40°C to 85°C), supply voltage range (4V to 32V), and all critical electrical parameters.

TL082CPT and TL082IPT (Functional Alternatives): These STMicroelectronics components represent functional alternatives with different amplifier topology (J-FET input stage). Selection of TL082 variants requires circuit-level evaluation due to modified electrical characteristics:

TL082CPT operates within 0°C to 70°C temperature range, which is narrower than the TL5580AIPWR specification.
TL082IPT extends the operating temperature range to -40°C to 105°C, providing broader temperature coverage.
Both TL082 variants feature significantly lower input bias current (20 pA vs. 100 nA) and higher slew rate (16 V/µs vs. 5 V/µs).
TL082 variants require minimum supply voltage of 6V (vs. 4V for TL5580AIPWR), restricting use in low-voltage applications.

TL082 variants are suitable only for applications where the modified electrical characteristics and higher minimum supply voltage do not conflict with circuit requirements. Both TL082 variants carry AEC-Q100 automotive qualification and active product status.

Frequently Asked Questions (FAQ)

Q: Can TL5580IPWR be used as a direct replacement for TL5580AIPWR?

A: Yes. The TL5580IPWR is electrically and mechanically identical to the TL5580AIPWR. Both components share the same base product number (TL5580), identical electrical specifications, 8-TSSOP package, and compliance certifications. The only difference is product status (Active vs. Last Time Buy). Pin-for-pin substitution is valid without circuit modification.

Q: What are the key differences between TL5580AIPWR and TL082 variants?

A: The primary differences are amplifier topology and electrical characteristics. TL5580AIPWR uses a general-purpose input stage with 100 nA input bias current and 5 V/µs slew rate. TL082 variants use J-FET input stages with 20 pA input bias current and 16 V/µs slew rate. Additionally, TL082 variants require minimum 6V supply voltage compared to 4V for TL5580AIPWR. These differences may affect circuit performance in low-voltage or precision applications.

Q: Are all substitute parts compatible with the 8-TSSOP package footprint?

A: Yes. All substitute parts (TL5580IPWR, TL082CPT, TL082IPT) use the 8-TSSOP surface mount package with identical dimensions (0.173", 4.40mm Width). PCB footprints and land patterns are mechanically compatible across all listed components.

Q: Which substitute part has the best inventory availability?

A: TL082IPT has the highest inventory availability at 5350 pcs, followed by TL082CPT at 2200 pcs and TL5580IPWR at 4100 pcs. The original TL5580AIPWR has limited inventory at 914 pcs due to Last Time Buy status.

Q: Can TL082CPT be used in applications requiring -40°C operation?

A: No. TL082CPT operates within 0°C to 70°C temperature range and does not support -40°C minimum temperature. TL082IPT extends the operating range to -40°C to 105°C and is suitable for extended temperature applications. Verify application temperature requirements before selecting between TL082 variants.

Q: Do all substitute parts maintain ROHS3 compliance?

A: Yes. All substitute parts (TL5580IPWR, TL082CPT, TL082IPT) are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance profile of the TL5580AIPWR.

Q: What is the minimum supply voltage requirement for each component?

A: TL5580AIPWR and TL5580IPWR operate from 4V minimum supply voltage. TL082CPT and TL082IPT require 6V minimum supply voltage. Applications using supply voltages between 4V and 6V are restricted to TL5580 variants only.
