概述
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 across the shunt as low as 10 mV full-scale.
The TPA183 does not have a separate VCC supply voltage pin. The operating supply voltage is internally connected to IN+ pin, drawing a maximum of 220 μA quiescent current.
All versions are specified from –40°C +125°C and offered in the SOT23-5 package.
