TPA183

概述

The TPA183 is a series of zero-drift, unidirectional current sense amplifiers that 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 the full-scale current sensing with maximum drops across the shunts to be as low as 10 mV.

The TPA183 series does not have a separate VCC supply voltage pin. The operating supply voltage is internally connected to the IN+ pin, drawing a maximum quiescent current of 220 μA.

The TPA183 series is specified from −40°C to +125°C, and offered in the SOT23-5 package.
