• Supply voltage range: Minimum 2.7 V, maximum 5.5 V
• Operating temperature range: -40°C to 125°C
• RoHS3 compliance and MSL rating

Functional Compatibility Parameters:

• Slew rate: 7 V/µs or greater
• Gain bandwidth product: 10 MHz or greater
• Input bias current: 2 pA or lower
• Input offset voltage: 250 µV or lower
• Supply current per channel: 800 µA or lower

Input offset voltage is 3 mV, significantly higher than the 250 µV specification. Supply current is 1 mA per channel, exceeding the 800 µA specification. Output current per channel is 25 mA, below the 28 mA specification. Supply voltage minimum is 2.4 V, extending the lower operating range. Both variants are Active with RoHS3 compliance and MSL 1 rating.

Alternative Substitute: MCP6L94T-E/ST (Microchip Technology)

The MCP6L94T-E/ST provides enhanced input offset voltage performance at 1 mV while maintaining the 14-TSSOP package and four-circuit configuration. Slew rate is 7 V/µs, matching the original specification. Supply current is 850 µA per channel, closely aligned with the 800 µA specification. Output current per channel is 25 mA. MSL rating is 3 (168 Hours), requiring controlled storage conditions. Product status is Active with RoHS3 compliance.

Performance-Enhanced Substitute: TSV994AIYPT (STMicroelectronics)

The TSV994AIYPT offers enhanced performance characteristics including 10 V/µs slew rate and 20 MHz gain bandwidth product, both exceeding the original specifications. Input offset voltage is 100 µV, superior to the 250 µV specification. The 14-TSSOP package and four-circuit configuration are maintained. Supply current is 820 µA per channel, closely aligned with the 800 µA specification. Output current per channel is 35 mA, exceeding the 28 mA specification. Supply voltage range is 2.5 V to 5.5 V. This part includes automotive qualification (AEC-Q100) and is Active with RoHS3 compliance and MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can TLV2624IPW be used as a direct replacement for TLV2624IPWG4?

A: Yes. The TLV2624IPW is electrically and mechanically identical to the TLV2624IPWG4. Both parts share the same base product number (TLV2624), identical electrical specifications, and 14-TSSOP package footprint. The primary difference is packaging format. Direct PCB substitution is supported.

Q: What are the key differences between the TLV2624IPWG4 and AD8694 series?

A: The AD8694 series (AD8694ARUZ, AD8694ARUZ-REEL, AD8694WARUZ) maintains the 14-TSSOP package and four-circuit configuration. Electrical differences include: slew rate of 5 V/µs versus 7 V/µs, input offset voltage of 400 µV versus 250 µV, supply current of 950 µA versus 800 µA per channel, and output current of 80 mA versus 28 mA per channel. Supply voltage range extends to 6 V maximum. These differences may affect circuit performance in applications sensitive to slew rate or input offset voltage specifications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain RoHS3 compliance status, consistent with the original TLV2624IPWG4 specification.

Q: What is the significance of MSL rating differences?

A: Most substitute parts maintain MSL 1 (Unlimited) rating, identical to the original part. The MCP6L94T-E/ST has MSL 3 (168 Hours), requiring controlled storage and handling procedures. MSL 3 components must be baked before reflow soldering if storage time exceeds 168 hours at 30°C and 85% relative humidity.

Q: Can the TSV994AIYPT be used in all applications requiring TLV2624IPWG4?

A: The TSV994AIYPT maintains the 14-TSSOP package and four-circuit configuration with superior performance characteristics (higher slew rate, lower input offset voltage, higher output current). However, the supply voltage maximum is 5.5 V, matching the original specification. Applications requiring the exact electrical characteristics of the TLV2624IPWG4 should verify compatibility with the enhanced performance parameters before substitution.

Q: What is the difference between AD8694ARUZ and AD8694ARUZ-REEL?

A: Both parts are electrically identical. The primary difference is packaging format: AD8694ARUZ is supplied in tube packaging, while AD8694ARUZ-REEL is supplied in cut tape and Digi-Reel format. Inventory availability differs, with AD8694ARUZ-REEL having significantly higher stock (20,300 units versus 7,943 units).

Q: Are MCP6294-E/ST and MCP6294T-E/ST interchangeable?

A: Both parts are electrically identical with identical specifications. The primary difference is packaging format: MCP6294-E/ST is supplied in tube packaging, while MCP6294T-E/ST is supplied in cut tape and Digi-Reel format. Inventory availability differs, with MCP6294T-E/ST having higher stock (7,768 units versus 5,300 units).

Q: Which substitute part offers the best performance upgrade?

A: The TSV994AIYPT provides the most significant performance enhancement with 10 V/µs slew rate (versus 7 V/µs), 20 MHz gain bandwidth product (versus 11 MHz), and 100 µV input offset voltage (versus 250 µV). This part also includes automotive qualification (AEC-Q100). However, performance enhancement may not be necessary for all applications, and design verification is required to confirm compatibility with existing circuit topology.

Q: What is the product status significance for long-term supply planning?

A: The original TLV2624IPWG4 is discontinued at DiGi Electronics. The TLV2624IPW is Last Time Buy, indicating limited future availability. All other substitute parts (AD8694 series, MCP6294 series, MCP6L94T-E/ST, TSV994AIYPT) are Active products with ongoing manufacturing and supply availability. For new designs or long-term production requirements, Active products are recommended.
