TLV2785IPWR Equivalent & Substitute Parts

Part Overview

The TLV2785IPWR is a general-purpose operational amplifier manufactured by Texas Instruments, featuring four independent amplifier circuits in a 16-TSSOP surface-mount package. This device is designated as Last Time Buy, indicating discontinued production with limited inventory availability. The TLV2785IPWR provides rail-to-rail output capability with low-power operation suitable for battery-powered and portable applications requiring multiple amplifier functions in a compact form factor.

Identification of equivalent and substitute parts is necessary due to the Last Time Buy status of the TLV2785IPWR. Alternative components with compatible electrical and mechanical specifications ensure design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2785IPWR is determined by strict equivalence of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Number of Circuits: 4 independent amplifier channels
• Amplifier Type: General Purpose operation
• Output Type: Rail-to-Rail capability
• Slew Rate: 5 V/µs
• Gain Bandwidth Product: 8 MHz
• Voltage Supply Range: 1.8 V to 3.6 V minimum
• Operating Temperature Range: -40°C to 125°C minimum
• Current - Input Bias: 2.5 pA
• Voltage - Input Offset: 250 µV
• Current - Supply: 650 µA (x4 Channels)
• Current - Output / Channel: 23 mA
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

Package Consideration: The TLV2785IPWR uses a 16-TSSOP package. Substitutes may use alternative TSSOP pin counts (such as 14-TSSOP) provided all electrical specifications remain equivalent and PCB layout accommodates the different package footprint.

Parameter Comparison

Engineering Selection Recommendations

TLV2784IPWR as Primary Substitute:

The TLV2784IPWR is the manufacturer-recommended substitute for the TLV2785IPWR. Both devices are manufactured by Texas Instruments and share identical electrical specifications across all critical parameters: four-channel general-purpose amplifier configuration, rail-to-rail output, 5 V/µs slew rate, 8 MHz gain bandwidth product, and identical supply voltage range (1.8 V to 3.6 V).

The primary difference is the package configuration: TLV2784IPWR uses a 14-TSSOP package compared to the 16-TSSOP of the TLV2785IPWR. Both packages maintain the same 0.173" width and 4.40 mm body width, allowing for straightforward PCB layout adaptation.

The TLV2784IPWR holds Active product status with higher inventory availability (1,900 pieces in stock versus 942 pieces for the TLV2785IPWR), providing superior supply chain continuity. Both devices maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring equivalent environmental and regulatory compliance.

Selection of the TLV2784IPWR requires verification that the 14-TSSOP footprint is compatible with the target PCB design. No electrical redesign is necessary.

Frequently Asked Questions (FAQ)

Q: Can the TLV2784IPWR directly replace the TLV2785IPWR without circuit modification?

A: The TLV2784IPWR provides electrical equivalence to the TLV2785IPWR across all specified parameters. However, the package change from 16-TSSOP to 14-TSSOP requires PCB layout modification. The pin assignments differ between these packages, necessitating footprint redesign. Electrical circuit operation remains unchanged.

Q: What is the significance of the Last Time Buy status for the TLV2785IPWR?

A: Last Time Buy designation indicates that Texas Instruments has discontinued production of the TLV2785IPWR. Current inventory (942 pieces) represents the final available stock. After depletion, the device will no longer be available from the manufacturer. Transition to the TLV2784IPWR or alternative substitutes is necessary for long-term design continuity.

Q: Are there electrical performance differences between the TLV2785IPWR and TLV2784IPWR?

A: No. Both devices share identical electrical specifications: 4-channel general-purpose amplifier configuration, 5 V/µs slew rate, 8 MHz gain bandwidth product, 2.5 pA input bias current, 250 µV input offset voltage, 650 µA total supply current, 23 mA output current per channel, and 1.8 V to 3.6 V supply voltage range. Operating temperature range is identical at -40°C to 125°C.

Q: What is the impact of the package change from 16-TSSOP to 14-TSSOP?

A: The 14-TSSOP package is physically smaller than the 16-TSSOP, reducing board space requirements. Both packages maintain the same 0.173" width and 4.40 mm body width. Pin count reduction from 16 to 14 reflects different pin assignments; however, all four amplifier circuits and required power/ground connections are preserved. PCB footprint redesign is mandatory.

Q: Do the TLV2785IPWR and TLV2784IPWR have identical compliance certifications?

A: Yes. Both devices are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity rating. ECCN classification (EAR99) and HTSUS code (8542.33.0001) are identical, ensuring equivalent regulatory and export compliance.

Q: What inventory considerations apply to substitution?

A: The TLV2784IPWR has significantly higher inventory availability (1,900 pieces in stock) compared to the TLV2785IPWR (942 pieces). This inventory advantage, combined with Active product status, makes the TLV2784IPWR the preferred long-term supply source for new designs and production continuity.
