Frequently Asked Questions (FAQ)

Q: Can the ISL28213FUZ-T7 directly replace the APX358M8G-13 in all applications?

A: The ISL28213FUZ-T7 maintains identical package (8-MSOP), mounting type (Surface Mount), number of circuits (2), and output type (Rail-to-Rail) specifications. The supply voltage range is compatible (1.8 V to 5.5 V encompasses the APX358M8G-13 range of 2.5 V to 5.5 V). The ISL28213FUZ-T7 offers improved input bias current (3 pA versus 10 nA) and input offset voltage (500 µV versus 1.7 mV). Extended operating temperature to 125°C provides additional capability. Direct substitution is valid from an electrical and mechanical standpoint.

Q: What is the difference between the LTC6084 CMOS variants and the original APX358M8G-13?

A: The LTC6084CMS8#PBF and LTC6084HMS8#PBF utilize CMOS technology, resulting in ultra-low input bias current (1 pA) compared to the APX358M8G-13 (10 nA). Input offset voltage is reduced to 300 µV. The slew rate is lower (0.5 V/µs versus 1 V/µs), and gain bandwidth product is 1.5 MHz versus 1 MHz. Both maintain 8-MSOP packaging and 2.5 V to 5.5 V supply range. The LTC6084HMS8#PBF extends operating temperature to 125°C, while the CMS8 variant operates 0°C to 70°C.

Q: Why are the LTC6247 parts marked as Last Time Buy?

A: Last Time Buy designation indicates these products are in the final phase of production and will be discontinued. While currently available, long-term supply cannot be guaranteed. These parts offer significantly higher performance (180 MHz gain bandwidth product, 90 V/µs slew rate) suitable for high-speed applications. Selection should consider future availability requirements and application performance needs.

Q: Are all substitute parts available in the same packaging options as the APX358M8G-13?

A: All listed substitute parts are available in 8-MSOP surface mount packaging. Packaging variants differ by supplier format: some are supplied in Tube, others in Cut Tape (CT) & Digi-Reel®, or Tape & Reel (TR). The physical package dimensions (0.118", 3.00mm Width) are identical across all parts, ensuring PCB layout compatibility.

Q: What is the significance of Moisture Sensitivity Level (MSL) differences?

A: MSL rating indicates the maximum time a component can be exposed to moisture at specified temperature and humidity conditions before soldering. The APX358M8G-13 has MSL 3 (168 hours), while most substitutes have MSL 1 (Unlimited). Lower MSL values provide greater handling flexibility and reduced risk of moisture-induced failures during storage and assembly. MSL 1 parts require no special moisture control measures.

Q: Which substitute offers the best low-power performance?

A: The ISL28213FUZ-T7 provides the lowest supply current at 90 µA (x2 Channels) compared to the APX358M8G-13 at 190 µA (x2 Channels). The LTC6084 variants consume 110 µA (x2 Channels). For applications prioritizing minimal power consumption, the ISL28213FUZ-T7 is the optimal selection while maintaining general purpose amplifier classification and active product status.

Q: Which substitute offers the highest output current capability?

A: The LTC6247 variants (LTC6247CMS8#PBF, LTC6247IMS8#PBF, and their tape & reel counterparts) provide 100 mA output current per channel, matching the APX358M8G-13. The ISL28213FUZ-T7 provides 22 mA, while LTC6084 variants provide 12.5 mA, and MCP6282/MCP6292 variants provide 25 mA per channel.

Q: Can the MCP6282 or MCP6292 be used in temperature-critical applications?

A: Both MCP6282-E/MS and MCP6292-E/MS support operating temperatures from -40°C to 125°C, exceeding the APX358M8G-13 range of -40°C to 85°C. These parts are suitable for extended temperature applications. The MCP6292-E/MS offers higher bandwidth (10 MHz) and slew rate (7 V/µs) compared to MCP6282 (5 MHz, 2.5 V/µs).
