3peak TP181A3-CR Current Sensing Amplifiers

　　The TP181 series of zero-drift,bi-directional current sense amplifier can sense voltage drops across shunts at commonmode voltages from–0.3V to 36V,independent of the supply voltage.Three fixed gains are available:50V/V,100V/V and 200V/V.The low offset of the zero-drift architecture enables current sensing with maximum drops across the shunt as low as 10mV full-scale.

　　TP181 devices operate from a single+2.7V to 30V power supply,with drawing a typical of 120uA of supply current.All versions are specified from–40°C+125°C,and offered in SC70-6 packages.
