The feasibility of substituting LM158DT for the original BA4580RF-E2 is relatively low, primarily due to key technical differences. First, the slew rate (0.6 V/µs) and gain bandwidth product (1.1 MHz) of the LM158DT are significantly lower than those of the BA4580RF-E2 (5 V/µs and 5 MHz). In high-speed signal processing applications, this could lead to sluggish response and insufficient bandwidth. Second, the input offset voltage of the LM158DT (5 mV) is much higher than that of the BA4580RF-E2 (300 µV), introducing greater DC error and compromising the accuracy of precision amplification circuits. Although the LM158DT offers lower input bias current (20 nA vs. 100 nA) and supply current (approximately 1.4 mA vs. 6 mA), which is advantageous for high-impedance and low-power designs, and its automotive-grade qualification (AEC-Q100) enhances environmental reliability, the slight difference in package width (3.90 mm vs. 4.40 mm) may cause mechanical compatibility issues. If the application does not demand high speed or precision, and prioritizes low power consumption or automotive environmental suitability, the LM158DT could serve as an alternative. Otherwise, direct substitution is not recommended.
