TS1109 Bidirectional Current-Sense Amplifier with Buffered Bipolar Output

The TS1109 incorporates a bidirectional current-sense amplifier plus a buffered bipolar output with an adjustable bias. The internal configuration of the TS1109 high-side current-sense amplifier is a variation of the TS1101 bidirectional current-sense amplifier, consuming 0.68 μA(typ) and 1.2 μA(max). The current-sense amplifier’s buffered output consumes only 0.76 μ A(typ) and 1.3 μA(max) of supply current. With an input offset voltage of 150 μV(max) and a gain error of 1%(max), the TS1109 is optimized for high precision current measurements.
