2. AZV832MMTR‑G1 Substitution Conclusion The AZV832MMTR‑G1 is a highly feasible drop‑in replacement for the TS1872AIST in the same package, though key performance differences must be considered. Its CMOS architecture provides extremely low input bias current (1 pA vs. 70 nA) and low input offset voltage (500 µV vs. 1 mV), along with superior input impedance and precision, making it suitable for high‑sensitivity signal amplification. The slew rate (0.45 V/µs vs. 0.6 V/µs) and gain‑bandwidth product (1 MHz vs. 1.8 MHz) are slightly lower, which may degrade performance in high‑speed applications. On the positive side, its output current capability is significantly higher (185 mA vs. 80 mA), enabling it to drive heavier loads such as motors or LEDs. The total supply current is also lower (70 µA vs. an estimated 1000 µA for the original), contributing to power savings. However, the maximum supply voltage of 5.5 V (vs. 6 V) restricts use in 6 V systems, and differences between CMOS and the original standard amplifier architecture could affect noise or stability behavior. Overall, if the application does not require 6 V operation and can tolerate slightly lower speed, the AZV832 is an excellent substitute, particularly in scenarios demanding high output drive and low power consumption.
