1. Substitution Conclusion for AZV358GTR-E1
The AZV358GTR-E1 is a highly compatible drop-in replacement for the original LMV358IPWRG4. Both parts are identical in all key electrical parameters, including supply voltage range (2.7V to 5.5V), gain bandwidth product (1MHz), slew rate (1V/µs), input offset voltage (1.7mV), and quiescent current (210µA per channel). This ensures direct performance interchangeability in the vast majority of general-purpose amplification, filtering, and signal conditioning applications.
The primary distinction is the AZV358GTR-E1's superior output drive capability (60mA vs. 40mA), which provides greater performance margin when driving heavier loads, such as multiple LEDs or capacitive loads, without introducing any performance degradation post-substitution. Furthermore, the packages are identical (8-TSSOP) and pin-compatible.
It is important to note the manufacturer has changed from Texas Instruments to Diodes Incorporated. There may be subtle differences in parameters not explicitly listed in the datasheets, such as behavior under extreme temperature conditions, long-term drift, or noise spectral density. However, for general commercial-grade applications, this substitution is both viable and reliable.
2. Substitution Conclusion for AZV358GTR-G1
The AZV358GTR-G1 is also a viable alternative for the LMV358IPWRG4. All its critical performance parameters—power supply voltage, bandwidth, slew rate, input bias characteristics, and power consumption—match the original part, guaranteeing a direct functional replacement.
Similar to the E1 variant, the key difference from the original part is its higher output current capability (60mA vs. 40mA), which constitutes a positive enhancement by providing additional margin for load driving. This part is electrically identical to the AZV358GTR-E1. The distinction typically lies in order packaging, environmental certifications, or production lot identification (the "G1" suffix may indicate different reel packaging or specific compliance versions such as halogen-free). There is no difference in electrical performance or package (8-TSSOP).
Regarding electrical substitution feasibility, the conclusion for the AZV358GTR-G1 is identical to that of the E1 version: it is a direct drop-in replacement. However, it is necessary to verify during procurement that the packaging or compliance requirements denoted by the "G1" suffix align with production needs.
