TLV2342IPW Equivalent & Substitute Parts

Part Overview

The TLV2342IPW is a CMOS amplifier integrated circuit manufactured by Texas Instruments, featuring two independent circuits in an 8-TSSOP surface mount package. This device operates across a 2V to 8V supply voltage range and is designed for low-power applications requiring dual-channel amplification. The TLV2342IPW is designated as Last Time Buy, indicating that Texas Instruments has discontinued this product line. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure long-term component availability for new production runs and system updates.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2342IPW is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 8-TSSOP surface mount package to ensure mechanical and electrical compatibility with existing printed circuit board layouts.

Circuit Count: The substitute must provide two independent amplifier circuits to maintain functional equivalence in dual-channel applications.

Supply Voltage Range: The substitute must operate within or encompass the 2V to 8V supply voltage range of the original part. Substitutes with extended voltage ranges remain compatible.

Mounting Type: Surface mount technology must be preserved to ensure assembly process compatibility.

Compliance Standards: Both parts must maintain ROHS3 compliance and MSL Level 1 rating to satisfy regulatory and manufacturing requirements.

The TLV9102IPWR qualifies as a substitute based on these parameters: it provides two circuits in an 8-TSSOP package with surface mount configuration, operates across a 2.7V to 16V supply range (encompassing the original 2V to 8V requirement), and maintains identical compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TLV2342IPW is designated Last Time Buy, indicating end-of-life status. The TLV9102IPWR maintains Active product status, ensuring ongoing availability and manufacturing support from Texas Instruments.

Compliance and Certification: Both parts satisfy ROHS3 compliance requirements and maintain MSL Level 1 rating, confirming suitability for standard manufacturing and storage conditions without moisture sensitivity constraints.

Supply Voltage Compatibility: The TLV9102IPWR operates across a 2.7V to 16V supply range, which encompasses the original TLV2342IPW specification of 2V to 8V. Designs operating within the 2.7V to 8V window maintain direct compatibility. Designs requiring operation below 2.7V require circuit-level evaluation.

Package and Mounting Equivalence: Both parts utilize identical 8-TSSOP surface mount packaging, ensuring direct substitution at the board assembly level without layout modifications.

Functional Differences: The TLV9102IPWR provides rail-to-rail output capability and higher output current per channel (80 mA versus 30 mA), offering enhanced performance margins. The substitute exhibits lower input bias current (10 pA versus 0.6 pA) and improved input offset voltage (300 µV versus 1.1 mV), resulting in superior precision characteristics. These differences represent performance enhancements rather than limitations.

Frequently Asked Questions (FAQ)

Q: Can the TLV9102IPWR directly replace the TLV2342IPW in existing designs?

A: Direct substitution is possible for designs operating within the 2.7V to 8V supply voltage range. The identical 8-TSSOP package and dual-circuit configuration ensure mechanical and electrical compatibility. Designs requiring operation below 2.7V require circuit evaluation to confirm feasibility.

Q: What are the key differences between these two parts?

A: The TLV2342IPW is a CMOS amplifier with Last Time Buy status. The TLV9102IPWR is a general-purpose amplifier with Active status, offering rail-to-rail output, higher output current capability (80 mA versus 30 mA per channel), lower input bias current, and improved input offset voltage specifications. The substitute also supports extended operating temperature range (-40°C to 125°C versus -40°C to 85°C).

Q: Are there any supply voltage limitations when substituting?

A: The TLV9102IPWR minimum supply voltage is 2.7V, compared to 2V for the TLV2342IPW. Designs operating at 2V to 2.7V require verification that the substitute meets application requirements. The maximum supply voltage of the substitute (16V) exceeds the original specification (8V), providing additional design flexibility.

Q: Do both parts require identical PCB layout considerations?

A: Yes. Both parts use the 8-TSSOP surface mount package with identical pin configuration and spacing. Existing PCB layouts require no modification for component substitution.

Q: What is the significance of the Last Time Buy status for the TLV2342IPW?

A: Last Time Buy designation indicates that Texas Instruments has discontinued production of the TLV2342IPW. Existing inventory is available for a limited period, after which the part becomes unavailable. The TLV9102IPWR, with Active status, ensures long-term component availability for ongoing production requirements.

Q: Are compliance certifications identical between both parts?

A: Yes. Both the TLV2342IPW and TLV9102IPWR maintain ROHS3 compliance, MSL Level 1 rating, REACH Unaffected status, and identical ECCN and HTSUS classifications, confirming regulatory equivalence.

Q: How do the performance specifications compare?

A: The TLV9102IPWR provides superior performance in several areas: higher slew rate (4.5V/µs versus 3.6V/µs), lower input bias current (10 pA versus 0.6 pA), and better input offset voltage (300 µV versus 1.1 mV). The TLV2342IPW offers higher gain bandwidth product (1.7 MHz versus 1.1 MHz). The substitute provides higher output current per channel and extended temperature range, representing overall performance enhancement.
