Description

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.
