1. LM2902KAVQPWRG4Q1 Substitution Conclusion The LM2902KAVQPWRG4Q1 can serve as a direct replacement for the AS324GTR-G1 in terms of package compatibility (14-TSSOP) and core functionality (quad general-purpose op‑amp). However, the following key differences must be considered: - Lower supply voltage rating (32 V vs. 36 V), which may limit its use in higher‑voltage applications. - Higher quiescent current (1.4 mA/channel vs. 1 mA/channel), impacting low‑power designs. - Slightly higher input offset voltage (3 mV vs. 2 mV), potentially reducing DC accuracy. Advantages of the LM2902KAVQPWRG4Q1 include stronger output drive capability (60 mA vs. 40 mA), well‑specified dynamic performance (slew rate 0.5 V/µs, bandwidth 1.2 MHz), and AEC‑Q100 automotive qualification, making it suitable for high‑reliability environments. In summary, if the system operates at ≤32 V and can accommodate the slightly higher power consumption and offset voltage, this device can be used as a substitute—particularly where automotive or industrial robustness is required.
