TS1103: 2V to 25V, 1µa, 200µV VOS bidirectional Precision Current-Sense Amplifiers

The TS1103 is the latest addition to the TS1103 family of bi-directional current-sense amplifiers. Consuming a very low 1μA supply current, the TS1103 high-side current-sense amplifiers combine a 200-μV (max) VOS and a 0.6% (max) gain error for cost-sensitive applications. For all high-side bidirectional current-sensing applications, the TS1103s are self-powered and feature a wide input common-mode voltage range from 2V to 25V. A SIGN comparator digital output is also provided that indicates the direction of current flow depending on the external connections to the TS1103’s RS+ and RS- input terminals.

The SOT23 package makes the TS1103 an ideal choice for pcb-area-critical, supply-current-sensitive, high-accuracy current-sense applications in all battery-powered and portable instruments.

All TS1103s are specified for operation over the -40°C to +105°C extended temperature range.
