1. LM2902KVQPWRG4Q1 Substitution Conclusion From the perspective of core parameters and specifications, the LM2902KVQPWRG4Q1 (TI) can serve as a substitute for the LM2902AQT14-13 (Diodes). However, several key differences must be noted: the gain bandwidth product (1.2 MHz vs. 700 kHz) and slew rate (0.5 V/µs vs. 0.3 V/µs) are higher in the TI part, giving it better dynamic response and high‑frequency signal handling capability; the output current capability (60 mA vs. 40 mA) is greater, improving drive strength for capacitive or low‑impedance loads; the supply current per channel (1.4 mA vs. 1 mA) is slightly higher, leading to a modest increase in overall power consumption; the input offset voltage (3 mV vs. 2 mV) is marginally larger, which could have a subtle impact on applications demanding very high DC accuracy; regarding supply range (3–32 V vs. 2–36 V), the TI device has a higher minimum start‑up voltage (3 V), while the Diodes part offers slightly better support for very low voltage (2 V) and a higher maximum voltage (36 V). If the application requires improved bandwidth, slew rate, or output drive capability, and the supply voltage lies within 3–32 V, the TI device can be used as a drop‑in replacement and may enhance system performance. If the system must operate at 2–3 V or demands extremely low power consumption or higher DC accuracy, the impact of these differences should be carefully evaluated.
