数据: MAX49921: 0 to 70V, High-Precision Current-Sense Amplifier Data Sheet 数据手册
The MAX49921 is high-precision, unidirectional current-sense amplifier (CSA) with an operating input common-mode range from 0 to +70V, though the device is protected against input common-mode voltages down to -42V and up to +80V, thus providing protection against reverse-battery and high-voltage spikes.
