TSV625AIPT Equivalent & Substitute Parts

Part Overview

The TSV625AIPT is a CMOS amplifier integrated circuit manufactured by STMicroelectronics, configured as a 4-circuit rail-to-rail operational amplifier in a 16-TSSOP surface mount package. This device is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design requirements and production continuity. The TSV625AIPT operates across a wide supply voltage range of 1.5 V to 5.5 V and maintains performance across industrial temperature ranges from -40°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the TSV625AIPT are identified based on electrical and mechanical compatibility within the linear amplifier category. The primary substitution criteria are:

Electrical Parameters:

• Four-circuit configuration (quad amplifier)
• Rail-to-rail output capability
• CMOS amplifier topology
• Supply voltage range compatibility (minimum 1.5 V to 5.5 V operation)
• Slew rate and gain bandwidth product performance envelope
• Input bias current and input offset voltage characteristics
• Output current per channel capability

Mechanical Parameters:

• Surface mount technology
• 16-pin TSSOP package form factor (0.173" width, 4.40mm)
• Identical pin pitch and footprint compatibility

Compliance Parameters:

• ROHS3 compliance
• MSL Level 1 rating
• REACH unaffected status

Substitutes are grouped by their ability to meet these criteria while accounting for product status and availability.

Parameter Comparison

Engineering Selection Recommendations

TSV624AIPT (STMicroelectronics)

The TSV624AIPT is the primary substitute for the obsolete TSV625AIPT. Both devices share identical electrical specifications including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current per channel. Both operate across the full -40°C to 125°C temperature range and maintain the 1.5 V to 5.5 V supply voltage span. The TSV624AIPT is currently in active production status, ensuring long-term availability and supply chain continuity. The primary mechanical difference is the package configuration: TSV624AIPT uses a 14-TSSOP package versus the 16-TSSOP of the TSV625AIPT. This package difference requires PCB layout modification and is not a direct pin-for-pin replacement. Both devices maintain ROHS3 compliance and MSL Level 1 rating. The TSV624AIPT is available in higher inventory quantities (22,715 pieces) compared to the TSV625AIPT (919 pieces).

TLV2765IPWR (Texas Instruments)

The TLV2765IPWR is a general-purpose amplifier substitute that maintains the 16-TSSOP package form factor, enabling direct footprint compatibility with the TSV625AIPT. The TLV2765IPWR provides improved performance in slew rate (0.23 V/µs versus 0.14 V/µs) and gain bandwidth product (500 kHz versus 420 kHz). Input offset voltage is superior at 550 µV compared to 800 µV. However, the TLV2765IPWR has critical limitations: the maximum supply voltage is restricted to 3.6 V (versus 5.5 V for TSV625AIPT), the maximum operating temperature is limited to 85°C (versus 125°C), and output current per channel is significantly reduced to 10.2 mA (versus 74 mA). The TLV2765IPWR is classified as Last Time Buy, indicating limited future availability. This device is suitable only for applications operating within the constrained voltage and temperature ranges and not requiring high output current capability.

Frequently Asked Questions (FAQ)

Q: Can the TSV624AIPT be used as a direct pin-for-pin replacement for the TSV625AIPT?

A: No. While the TSV624AIPT and TSV625AIPT share identical electrical specifications, they use different package configurations. The TSV625AIPT uses a 16-pin TSSOP package, while the TSV624AIPT uses a 14-pin TSSOP package. PCB layout and routing modifications are required for substitution.

Q: What are the key electrical differences between the TSV625AIPT and TLV2765IPWR?

A: The TLV2765IPWR offers higher slew rate (0.23 V/µs versus 0.14 V/µs) and improved input offset voltage (550 µV versus 800 µV). However, it has a reduced maximum supply voltage of 3.6 V (versus 5.5 V), lower maximum operating temperature of 85°C (versus 125°C), and significantly lower output current per channel of 10.2 mA (versus 74 mA).

Q: Is the TLV2765IPWR suitable for applications requiring the full 5.5 V supply voltage range?

A: No. The TLV2765IPWR maximum supply voltage is 3.6 V. Applications requiring operation at 5.5 V must use the TSV625AIPT or TSV624AIPT.

Q: What is the inventory status of available substitutes?

A: The TSV624AIPT is in active production with 22,715 pieces in stock. The TLV2765IPWR is classified as Last Time Buy with 16,200 pieces in stock. The original TSV625AIPT is obsolete with 919 pieces remaining in inventory.

Q: Are both substitute parts ROHS3 compliant?

A: Yes. Both the TSV624AIPT and TLV2765IPWR are ROHS3 compliant with MSL Level 1 rating, matching the compliance profile of the TSV625AIPT.

Q: Which substitute is recommended for new designs?

A: The TSV624AIPT is recommended for new designs requiring electrical equivalence to the TSV625AIPT, provided PCB layout can accommodate the 14-pin TSSOP package. The TLV2765IPWR is suitable only for applications with supply voltages not exceeding 3.6 V and operating temperatures not exceeding 85°C.

Q: What is the operating temperature range difference between substitutes?

A: The TSV625AIPT and TSV624AIPT both operate from -40°C to 125°C. The TLV2765IPWR operates from -40°C to 85°C, limiting its use in high-temperature applications.

Q: Can the TSV624AIPT handle the same output current as the TSV625AIPT?

A: Yes. Both devices provide 74 mA output current per channel, maintaining identical current-sourcing capability.
