TS1100: +2.0V TO 25V, 1µA, 30µV VOS Precision Current-Sense Amplifiers

The voltage-output TS1100 current-sense amplifiers are form-factor identical and electrical improvements to the MAX9938 and the MAX9634 current-sense amplifiers. Consuming a very low 1μA supply current, the TS1100 high-side current-sense amplifiers exhibit a 100-μV (max) VOS and a 0.5% (max) gain error, both specifications optimized for any precision current
measurement. For all high-side current-sensing applications, the TS1100 features a wide input common-mode voltage range from 2V to 25V.

The SOT23 package makes the TS1100 an ideal choice for pcb-area-critical, low-current, highaccuracy current-sense applications in all batterypowered, remote or hand-held portable instruments.

All TS1100s are specified for operation over the -40°C to +105°C extended temperature range.
