The feasibility of substituting AD629ARZ-R7 with INA154U/2K5 is limited, primarily due to differences in amplifier type (current sense amplifier vs. general-purpose differential amplifier). The INA154U/2K5 may not be directly suitable for high-precision current sensing applications unless the external circuitry is redesigned to provide the required common-mode rejection and gain configuration. Additionally, the INA154U/2K5 has a minimum supply voltage of 8V, which is higher than the 5V requirement of the AD629ARZ-R7, restricting its direct replacement in low-voltage systems. While the INA154U/2K5 offers certain performance advantages—such as a higher slew rate (14V/µs vs. 2.1V/µs) and bandwidth (3.1 MHz vs. 500 kHz) for faster signal response and high-frequency signal handling, lower input offset voltage (100 µV vs. 200 µV) for potentially higher accuracy, and greater output current (60 mA vs. 25 mA) for stronger load drive capability—these improvements may be offset by its higher power consumption (2.4mA supply current vs. 900µA) and elevated supply voltage requirement. Therefore, substitution should be carefully evaluated based on application needs and system compatibility.
