概述
The TP181 series of zero-drift, bi-directional current sense amplifiers can sense voltage drops across shunts at commonmode voltages from –0.3 V to 36 V, independent of the supply voltage. Three fixed gains are available: 50 V/V, 100 ,V/V, and 200 V/V. The low offset of the zero-drift architecture enables current sensing with maximum drops across the shunt as low as 10 mV full-scale.
TP181 devices operate from a single +2.7-V to 30-V power supply, with drawing a typical of 120 uA of supply current. All versions are specified from –40°C +125°C, and offered in the SC70-6 package
