Zhongwei Aixin: Launches the AiP893XR—40V wide‑range supply, 7 MHz gain‑bandwidth product, and 22 V/µs slew rate, ensuring unwavering signal fidelity across the entire operating range.
The AiP893XR series is a high‑voltage, high‑slew‑rate, rail‑to‑rail output operational amplifier independently developed by Zhongwei Aixin. Its core performance matches that of comparable products in the same class, with all key parameters pushed to the limit: it supports a wide supply voltage range of 3 to 40 V, delivers a high slew rate of 22 V/µs and a gain–bandwidth product of 7 MHz, enabling fast, precise signal tracking and amplification. With a quiescent current of only 1 mA per channel and an open‑loop gain as high as 120 dB, it is ideally suited for high‑voltage, high‑speed amplification applications such as motor control, audio power amplification, and industrial signal chains, offering a highly stable and flexible solution for domestic substitution.
