TLV2785AID Equivalent & Substitute Parts

Part Overview

The TLV2785AID is a general-purpose operational amplifier featuring four independent circuits in a 16-SOIC surface-mount package. This device delivers rail-to-rail output capability with a 5V/µs slew rate and 8 MHz gain bandwidth product, suitable for low-power analog signal processing applications across industrial, consumer, and portable equipment designs.

The TLV2785AID carries a Last Time Buy product status, indicating that Texas Instruments has discontinued this part number. Identifying equivalent substitute components is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements for existing applications.

Substitute Part Grouping Explanation

Substitution of the TLV2785AID is determined by strict equivalence across the following critical parameters:

Functional Equivalence Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 4 independent channels
• Output Type: Rail-to-Rail
• Slew Rate: 5 V/µs
• Gain Bandwidth Product: 8 MHz
• Input Bias Current: 2.5 pA
• Input Offset Voltage: 250 µV
• Supply Current: 650 µA (total, x4 channels)
• Output Current per Channel: 23 mA
• Supply Voltage Range: 1.8 V to 3.6 V
• Operating Temperature: -40°C to 125°C

Compliance & Regulatory Equivalence:

• RoHS3 Compliance
• Moisture Sensitivity Level 1
• REACH Unaffected status
• ECCN EAR99 classification

The TLV2784IPWR qualifies as a direct functional substitute based on identical electrical performance specifications. The primary distinction lies in packaging format: the TLV2784IPWR uses a 14-TSSOP surface-mount package instead of the 16-SOIC package of the TLV2785AID. Both devices maintain identical electrical characteristics and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TLV2784IPWR

The TLV2784IPWR is the manufacturer-recommended substitute for the TLV2785AID. Both devices are produced by Texas Instruments and deliver identical electrical performance across all specified parameters. The TLV2784IPWR maintains active product status, ensuring continued availability and long-term supply chain support.

Substitution Feasibility:

The TLV2784IPWR is electrically interchangeable with the TLV2785AID. All functional parameters—including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range—are identical. Both devices operate across the same temperature range (-40°C to 125°C) and maintain equivalent regulatory compliance (ROHS3, REACH Unaffected, EAR99).

Package Consideration:

The primary design consideration is the package format difference. The TLV2785AID uses a 16-SOIC package (0.154" width, 3.90mm), while the TLV2784IPWR uses a 14-TSSOP package (0.173" width, 4.40mm). PCB layout modifications are required to accommodate the different pin configuration and package footprint. The 14-TSSOP package is smaller in overall height and offers improved thermal characteristics compared to the 16-SOIC package.

Compliance & Regulatory Status:

Both parts maintain ROHS3 compliance, Moisture Sensitivity Level 1 (unlimited shelf life), and REACH Unaffected status. No regulatory or environmental restrictions apply to either device. The TLV2784IPWR's active product status provides assurance of continued manufacturing and technical support from Texas Instruments.

Frequently Asked Questions (FAQ)

Q: Can the TLV2784IPWR directly replace the TLV2785AID without circuit modifications?

A: The TLV2784IPWR is electrically equivalent to the TLV2785AID and requires no circuit modifications. However, PCB layout changes are necessary due to the different package format (14-TSSOP versus 16-SOIC). Pin assignments differ between the two packages, requiring schematic and layout redesign.

Q: What is the primary difference between the TLV2785AID and TLV2784IPWR?

A: The devices are functionally identical in electrical performance. The main difference is the package format: TLV2785AID uses 16-SOIC, while TLV2784IPWR uses 14-TSSOP. The TLV2784IPWR also ships in Tape & Reel format rather than Tube packaging.

Q: Why is the TLV2785AID marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued this part number. The TLV2784IPWR is the active replacement, offering identical electrical performance in a different package format.

Q: Are there any thermal or reliability differences between the two packages?

A: The 14-TSSOP package used in the TLV2784IPWR provides improved thermal performance compared to the 16-SOIC package. Both packages maintain identical electrical specifications and operating temperature ranges (-40°C to 125°C).

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the TLV2785AID and TLV2784IPWR are ROHS3 compliant, REACH Unaffected, and classified as EAR99. Both maintain Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What is the supply current difference between the two devices?

A: There is no difference. Both devices consume 650 µA total supply current across all four channels, with identical per-channel output current capability of 23 mA.

Q: Can I use the TLV2784IPWR in high-volume production?

A: Yes. The TLV2784IPWR carries active product status from Texas Instruments, ensuring continued manufacturing availability and technical support for high-volume applications.
