Silicon Labs TS1105-20DB, Current Sensing Amplifier Demonstration Board for TS1105-20

Demonstration boards for the Silicon Labs TS1105 Unidirectional Current Sense Ampliter with buffered unipolar output and adjustable bias. The TS1105 high-side current-sense amplifier uses 0.68 μA (typical) and buffered output 0.76 μA (typical).

Available with two gain options;
20 V/V - TS1105-20 (RS 894-7083)
200 V/V - TS1105-200 (RS 894-7089)

These boards are fully assembled and tested.

The TS1105 has a wide input voltage range from 2 to 25 Volts and are available in 8-pin TDFN packages.

Current Sensing Amplifiers have a voltage output that is proportional to the volt drop across a very low value resistor, usually in a high-current power rail. Hence they measure the current flowing in that power rail.
