TS1105/06 Data Sheet

TS1105 and TS1106 Unidirectional and Bidirectional Current-

Sense Amplifiers + Buffered Unipolar Output with Adjustable Bias

The TS1105 and TS1106 combine the TS1100 or TS1101 current-sense amplifiers with

a unipolar buffered output featuring adjustable bias.

The TS1105 and TS1106 high-side current-sense amplifiers consume 0.68 μA (typ) and

1.2 μA (max) of supply current while the buffered output consumes 0.76 μA (typ) and 1.3

μA (max) of supply current. With an input offset voltage of 100 μV (max) and a gain error

of 0.6% (max), the TS1105 and TS1106 are optimized for high-precision current meas-

urements.
