Product Description
AD8418BRMZ Integrated Circuit Chip Bidirectional Zero-Drift Current Sense Amplifier MSOP-8
Product Overview
AD8418BRMZ is a high voltage, high resolution current shunt amplifier featuring an initial gain of 20 V/V with maximum ±0.15% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter.
This amplifier offers excellent input common-mode rejection from −2 V to +70 V and performs bidirectional current measurements across a shunt resistor in various automotive and industrial applications.
