DESCRIPTION

The voltage-output TS1101 current-sense amplifiers are Touchstone Semiconductor’s first proprietary bidirectional current-sense amplifiers. Consuming a very low 1µA supply current, the TS1101 high-side current-sense amplifiers exhibit a 100-µV (max) VOS and a 0.6% (max) gain error, both specifications optimized for any precision current measurement. For all high-side bidirectional current-sensing applications, the TS1101s 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 TS1101’s RS+ and RS- input terminals.

The SOT23 package makes the TS1101 an ideal choice for pcb-area-critical, supply-current-conscious, high-accuracy current-sense applications
in all battery-powered and portable instruments.

All TS1101s are specified for operation over the -40°C to +105°C extended temperature range.
