TPA191 - Bi-Directional Current Sense Amplifier
The TPA191 series of zero-drift, bi-directional current sense amplifier can sense voltage drops across shunts at common-mode voltages from *0.3 V to 36 V, independent of the supply voltage.
Five fixed gains are available: 20 V/V, 50 V/V, 75 V/V, 100 V/V, and 200 V/V.
