The TPA183 series of zero-drift, unidirectional currentsense amplifiers can sense voltage drops acrossshunts at common-mode voltages from 2.7 V to 30 V.The TPA183 series supports a voltage output withoptions of four fixed gains: 25 V/V, 50 V/V, 100 V/V,and 200 V/V. The low offset of the zero-driftarchitecture enables current sensing with maximumdrops across the shunt as low as 10 mV full-scale.The TPA183 does not have a separate VCC supplyvoltage pin. The operating supply voltage is internallyconnected to IN+ pin, drawing a maximum of 220 μAquiescent current.All versions are specified from –40°C +125°C andoffered in the SOT23-5 package.
