TPA127(3PEAK)

The TPA127 is a high-side, unidirectional current-sensing amplifier with a current output. Although designed for current shunt measurement, the device is also well suited for measurement and level conversion in creative applications. The device converts the differential input voltage to a current output by its transconductance characteristic. The output current flows through the external load resistor and generates the output voltage. The gain between the output voltage and differential input voltage can be set from 1 to over 100 by the product of the external load resistor and transconductance. The supply and input voltages are independent and operate from 3 V to 60 V. The device is available in the SOT23-5 package. Its operating temperature range is from −40°C to +125°C.
