描述 Description

The TP199 series of zero-drift, bi-directional current sense amplifier can sense voltage drops across shunts at common-mode voltages from –0.3V to 36V, independent of the supply voltage. Two fixed gains are available: 50V/V, and 100V/V. The low offset of the zero-drift architecture enables current sensing with maximum drops across the shunt as low as 10mV full-scale.

TP199 devices operate from a single +2.7V to 36V 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.
