TPA183 - 3PEAK

TPA183 Precision Current Sense Amplifier

The TPA183 series of zero-drift, unidirectional current sense amplifiers can sense voltage drops across shunts at common-mode voltages from 2.7 V to 30 V. The TPA183 series supports a voltage output with options of four fixed gains: 25 V/V, 50 V/V, 100 V/V, and 200 V/V. The low offset of the zero-drift architecture enables current sensing with maximum drops .
