概述
The TP182 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.
TP182 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.
